Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

In the AR/VR technology, three-dimensional GUI (Graphical User Interface ) elements are indispensable elements in an interactive interface, for example, three-dimensional buttons, three-dimensional windows, and the like. In order to adapt to different scenes, it is generally necessary to stretch or compress a three-dimensional GUI element, and since the three-dimensional GUI element is a model constructed by a plurality of points and triangular surfaces, the model of the three-dimensional GUI element needs to be reconstructed because the three-dimensional GUI element is easily deformed when adjustment such as stretching or compression is performed.

Through researches, the inventor provides a three-dimensional model adjustment method, a device, terminal equipment and a storage medium in the embodiment of the application, so that the complexity of adjusting three-dimensional GUI elements can be reduced.

The application scenario of the three-dimensional model adjustment method provided in the embodiment of the present application is described below.

Referring to fig. 1, a display system provided in an embodiment of the present application includes a terminal device 100 and an interaction device 200.

In some embodiments, the terminal device 100 may be a head-mounted display device, a mobile phone, a tablet computer, a personal computer, or the like, where the head-mounted display device may be an integral head-mounted display device, or may be a head-mounted display device connected to an external electronic device. The terminal device 100 may also be an intelligent terminal such as a mobile phone connected to an external/access type head-mounted display device, that is, the terminal device 100 may be used as a processing and storage device of the head-mounted display device, and the external type head-mounted display device may be inserted or accessed, so that the virtual object 300 may be displayed through the head-mounted display device, where the virtual object 300 may include three-dimensional GUI elements such as icons, tables, options, and the like.

In some embodiments, the user may interact with the virtual object 300 displayed by the terminal device 100 through the interaction device 200, where the interaction device 200 may be an electronic device such as a keyboard, a tablet computer, a mouse, a handle, and the like, but is not limited thereto. As one way, at least one interaction region may be provided on the interaction device 200, through which a user may perform related control and interaction with the virtual object 300. The interaction area may include at least one of a key, a roller, a touch screen, etc., and the specific shape, structure and size of the interaction device in the embodiment of the present application are not limited, and may be various shapes, such as square, round, or various shapes. As another embodiment, the user may interact with the virtual object 300 through a gesture, and at this time, the terminal device 100 may receive a gesture instruction of the user, and perform corresponding control on the virtual object 300 according to the gesture instruction.

In some embodiments, the terminal device 100 and the interaction device 200 may be connected through Wireless communication modes such as bluetooth, wiFi (Wireless-Fidelity), zigBEE (ultraviolet technology), and the like, or may be connected through wired communication through a data line, etc., and of course, the connection mode of the terminal device 100 and the interaction device is not limited in the embodiments of the present application.

Referring to fig. 2, an embodiment of the present application provides a three-dimensional model adjustment method, which is applied to a terminal device, and the method may include:

step S110: and acquiring cutting parameters of the GUI elements of the three-dimensional graphical user interface to be adjusted.

In one embodiment, the terminal device may obtain a cutting parameter of the three-dimensional GUI element to be adjusted, where the cutting parameter may be a parameter input by the user based on the three-dimensional GUI element to be adjusted, may also be a history parameter, or may also be a parameter preset in the terminal device. The GUI elements may be used to implement interaction between the user and the terminal device, and may be graphical objects in the interface, for example, the GUI elements may include a prompt box, a pop-up box, a warning box, a dialog box, a pull-up menu, a simple menu, an active view, a confirmation pop-up box, a full screen pop-up box, a modal view, and the like, where a plurality of sub-GUI elements may be included under the GUI elements. For example, the pull-up menu may include not only a cancel sub-GUI element but also a delete sub-GUI element, etc., and the GUI element specifically refers to which of these are not explicitly limited.

In one embodiment, the GUI elements may be divided into two-dimensional GUI elements and three-dimensional GUI elements, wherein the three-dimensional GUI elements may be generated by acquiring the dimensions of the user interface to be generated in the X-axis direction and the Y-axis direction of the three-dimensional space and the scaling coefficients corresponding to the layers distributed in the Z-axis direction. The three-dimensional GUI element to be adjusted refers to the three-dimensional GUI element whose size or dimension needs to be adjusted in the terminal device, so that before acquiring the cutting parameter of the three-dimensional GUI element to be adjusted, it may be determined which three-dimensional GUI element to be adjusted is, that is, the three-dimensional GUI element to be adjusted may be specified by the user or may be defaulted by the terminal device. For example, the three-dimensional GUI element dialog box may be used as a default three-dimensional GUI element to be adjusted, mainly because the aspect ratio of the three-dimensional GUI element may be changed continuously with the continuous input of the session content. And the cutting parameters mainly include a horizontal cutting line and a vertical cutting line for cutting the three-dimensional GUI element to be adjusted into a plurality of areas, such as 9 areas, 27 areas, or the like, by which the three-dimensional GUI element to be adjusted can be cut into a plurality of areas, for example, but not limited thereto.

Step S120: and cutting the three-dimensional GUI element to be adjusted into a plurality of areas according to the cutting parameters, and determining an adjustment area and a fixed area in the plurality of areas, wherein the fixed area is a corner area of the three-dimensional GUI element to be adjusted.

In one embodiment, the terminal device acquires the cutting parameters to cut the three-dimensional GUI element to be adjusted into a plurality of areas, and then determines which areas of the plurality of areas are adjustable in aspect ratio, which areas are not adjustable in aspect ratio, and refers to the adjustable areas as adjustment areas, and the non-adjustable areas as fixed areas. The fixed area in the embodiment of the present application may be a corner area of the three-dimensional GUI element to be adjusted, where the corner area refers to an area including corners of the GUI element, for example, the GUI element is a three-dimensional model of a rectangle, and the corner area may be an area including corners of the rectangle. If the cutting parameters are different, the number of the areas cut by the three-dimensional GUI element to be adjusted is also different, for example, when the cutting parameters include information of two horizontal cutting lines and two vertical cutting lines, the three-dimensional GUI element to be adjusted may be cut into 9 areas, and when the cutting parameters are two transverse lines and eight longitudinal lines, the three-dimensional GUI element to be adjusted may be cut into 27 areas, and specifically, how many areas the three-dimensional GUI element to be adjusted is cut into is not limited explicitly here, and may be cut according to practical situations.

For a clearer illustration of the region division of the three-dimensional GUI element to be adjusted, taking the box diagram shown in fig. 3 as an example, the 9 regions given in fig. 3 may be respectively numbered, i.e. the nine regions are the 1 st region, the 2 nd region, the 3 rd region, the 4 th region, the 5 th region, the 6 th region, the 7 th region, the 8 th region and the 9 th region, respectively. The 1 st, 3 rd, 7 th and 9 th regions in fig. 3 are corner regions of the three-dimensional GUI element to be adjusted, that is, the shapes of the regions corresponding to the four numbers are not changed when the stretching or compressing operation is performed on the three-dimensional GUI element to be adjusted, so the four regions may be referred to as fixed regions. The 2 nd, 4 th, 5 th, 6 th and 8 th regions may be referred to as adjustment regions since the aspect ratio thereof may be changed according to the execution of the stretching or compressing operation. In addition, the 2 nd, 4 th, 5 th, 6 th and 8 th regions may be further divided according to different positions of each region, and specifically, the 2 nd and 8 th regions may be referred to as horizontal adjustment regions, i.e., the aspect ratio of the 2 nd and 8 th regions may be changed when performing a horizontal stretching or compressing operation; the 4 th and 6 th regions are referred to as vertical adjustment regions, i.e., the aspect ratio of the 4 th and 6 th regions can be changed when performing a vertical stretching or compressing operation; the 5 th region may be referred to as a full adjustment region, i.e., the aspect ratio of the 5 th region may be simultaneously horizontally and vertically pulled up or compressed when the three-dimensional GUI element to be adjusted is adjusted.

In one embodiment, the determination of the adjustment area and the fixed area may be dependent on the shape characteristics of the three-dimensional GUI element to be adjusted. For example, the portion of the three-dimensional GUI element to be adjusted, which is deformed or distorted after being stretched, may be cut in a fixed area (e.g., a corner area) according to need, and the cutting parameters may be determined according to the shape and size of the corner area of the three-dimensional GUI element to be adjusted. For example, in practical applications, the three-dimensional GUI element to be adjusted often has rounded corners, and therefore, the position coordinates of the cutting line may be determined according to the diameter of the rounded corners, so that in the three-dimensional GUI element to be adjusted after cutting, the rounded corners are included in a fixed area that is not stretched, and thus, problems of deformation distortion may be prevented from occurring. In addition, it should be understood by those skilled in the art that references to "stretching" in this disclosure refer to increasing the height and/or width of the three-dimensional GUI element to be adjusted, while references to "compressing" refer to decreasing the height and/or width of the three-dimensional GUI element to be adjusted.

Step S130: adjustment parameters input for the three-dimensional GUI element to be adjusted are acquired.

In some embodiments, the adjustment parameters input for the three-dimensional GUI element to be adjusted may be input by the user according to the actual situation of the three-dimensional GUI element to be adjusted, or may be preset by the terminal device, or may be historical adjustment parameters. The user can adjust the three-dimensional GUI element to be adjusted according to the self requirement, namely, the user can input adjustment parameters aiming at the three-dimensional GUI element to be adjusted, and the adjustment parameters can be input through interaction devices such as a mouse, a keyboard, a touch pad and the like or gestures.

In a specific embodiment, the user may press or move the interaction device to input the adjustment parameter, so as to implement adjustment of the three-dimensional GUI element to be adjusted, in this process, the terminal device may perform real-time detection on the three-dimensional GUI element to be adjusted and the virtual indication cursor, that is, whether the boundary coordinates of the virtual indication cursor and the three-dimensional GUI element to be adjusted intersect, if the boundary coordinates of the three-dimensional GUI element to be adjusted intersect with the virtual indication cursor, the adjustment parameter input operation is triggered, and if the boundary coordinates of the three-dimensional GUI element to be adjusted and the virtual indication cursor do not intersect, the adjustment parameter cannot be successfully input, as a way, the position of the virtual indication cursor may be moved by the interaction device. When the adjustment parameter input operation is successfully triggered, the adjustment of the three-dimensional GUI element to be adjusted can be achieved by pressing or moving the interactive device.

The adjustment parameters in the embodiment of the present application may be divided into a horizontal adjustment parameter, a vertical adjustment parameter and a diagonal adjustment parameter, when a user adjusts a three-dimensional GUI element to be adjusted through a horizontal movement operation, the generated adjustment parameter is the horizontal adjustment parameter, specifically, the three-dimensional GUI element to be adjusted may be adjusted by moving a horizontal cutting line through an interaction device, or a boundary of the GUI element may also be directly dragged to move in a horizontal direction, or the like; when a user adjusts the three-dimensional GUI element to be adjusted through vertical movement operation, the generated adjustment parameters are vertical adjustment parameters, and the user can adjust the three-dimensional GUI element to be adjusted through moving a vertical cutting line, or the user can directly drag the boundary of the GUI element to move vertically, and the like; when the user adjusts the three-dimensional GUI element to be adjusted through the diagonal movement operation, the generated adjustment parameters are diagonal adjustment parameters, and meanwhile, the user can adjust the three-dimensional GUI element to be adjusted through moving the diagonal cutting line, or the user can directly drag the boundary of the GUI element to move in the diagonal direction, and the like. Optionally, the adjustment parameters may be input in combination with a pressing operation and a moving operation, that is, when it is determined that the virtual pointing cursor intersects with coordinates of the three-dimensional GUI element to be adjusted, the pressing operation may be acquired first, whether there is a moving operation input is determined based on the pressing operation, and if there is a moving operation input, the three-dimensional GUI element to be adjusted may be adjusted according to the moving operation.

As can be seen from the above description, the adjustment parameters may include a horizontal adjustment parameter, a vertical adjustment parameter, or a diagonal adjustment parameter, etc., and the terminal device may detect whether the adjustment parameter acquired by the terminal device is a horizontal adjustment parameter after acquiring the adjustment parameter input for adjusting the three-dimensional GUI element, if the adjustment parameter acquired by the terminal device is a horizontal adjustment parameter, the terminal device may further determine whether the horizontal adjustment parameter is less than or equal to a first preset threshold, if the horizontal adjustment parameter is less than or equal to the first preset threshold, it indicates that the adjustment parameter is successfully input, and then step S140 is entered. If the horizontal adjustment parameter is larger than the first preset threshold, the failure of the adjustment parameter input is indicated, and at the moment, the terminal equipment can prompt a user that the adjustment parameter input fails in a mode of images, texts or voices and the like. For example, the terminal device may prompt the user in a text manner in the virtual environment, where the text content may be "the level adjustment parameter input by the host is too large to perform the adjustment operation, please re-perform the adjustment parameter input operation, or forgo performing the current operation-! ".

In addition, if the adjustment parameter acquired by the terminal device is not the horizontal adjustment parameter, it is determined whether the adjustment parameter is a vertical adjustment parameter, if the adjustment parameter acquired by the terminal device is the vertical adjustment parameter, the terminal device may further determine whether the vertical adjustment parameter is less than or equal to a second preset threshold, if the vertical adjustment parameter is less than or equal to the second preset threshold, it indicates that the adjustment parameter is successfully input, and step S140 is performed at this time. If the vertical adjustment parameter is larger than the second preset threshold, the failure of the adjustment parameter input is indicated, and at the moment, the terminal equipment can prompt the user that the failure of the adjustment parameter input is indicated through the modes of images, texts or voices. For example, the terminal device may prompt the user in a voice manner that "the vertical adjustment parameter input is too large to adjust the three-dimensional GUI element to be adjusted according to your requirements, which is troublesome for the host to re-perform the adjustment parameter input operation".

In other embodiments, if the adjustment parameter acquired by the terminal device is not the vertical adjustment parameter, it indicates that the acquired adjustment parameter is a diagonal adjustment parameter, and at this time, the terminal device may further determine whether the diagonal adjustment parameter is less than or equal to a third preset threshold, and if the diagonal adjustment parameter is less than or equal to the third preset threshold, it indicates that the adjustment parameter is successfully input, and at this time, step S140 is entered. If the diagonal adjustment parameter is larger than a third preset threshold, the adjustment parameter input failure is indicated, and at the moment, the terminal equipment can prompt a user that the adjustment parameter input fails in an image, text or voice mode. For example, the terminal device may graphically prompt the user, i.e., a red error icon may be displayed in the virtual environment to prompt the user that the adjustment parameter input failed.

It should be noted that, the user may input the adjustment parameter value terminal device through a gesture or a keyboard, and when the adjustment parameter is input by using the gesture, it may be determined which type the input adjustment parameter belongs to by detecting the motion track of the gesture. For example, when the terminal device detects that the gesture of the user is a horizontal movement to the right, it may determine that the inputted adjustment parameter is a horizontal adjustment parameter. When the keyboard is used for inputting the adjustment parameters, the keyboard can be used for selecting the direction to be adjusted, and the adjustment parameters of the direction can be input on the basis. For example, the mode of first inputting the data to be adjusted through the keyboard is horizontal to the right relative to the terminal equipment, and then inputting the data to be adjusted through the keyboard is amplified by 2 times, and the adjustment parameter at the moment is amplified by 2 times horizontally to the right.

Step S140: and adjusting the grid information of the adjustment area according to the adjustment parameters to obtain the adjusted three-dimensional GUI element.

After the terminal equipment acquires the adjustment parameters, the grid information of the adjustment area can be adjusted according to the adjustment parameters, and then the adjusted three-dimensional GUI element is obtained. The mesh information may also be called mesh information, and the mesh is a component in Unity, which refers to a mesh of a model, and main attribute contents of the mesh include vertex coordinates (vertex), normal (normal), texture coordinates (uv), triangle drawing sequences (triangle), and other useful attributes and functions. Vertex coordinates (vertex) are mainly used for storing the space coordinates of each vertex of a mesh, and if n vertexes exist in a mesh, the size of vertex is n; the normal (normal) is mainly used for storing the normal of each vertex of the mesh, and the size of the normal corresponds to the vertex coordinates, for example, normal [ i ] is the normal of vertex [ i ]; texture coordinates (uv), which are information defining the location of each point on the picture and which determine the location of the surface texture map, are the surfaces of the three-dimensional GUI elements to which each point on the image corresponds with accuracy, and uv [ i ] corresponds with vertex [ i ]; a triangle sequence (triangle) consists of several triangles, and the three points of the triangle are points in the vertex coordinates, and the size of the triangle array=the number of triangles is 3. For example, four vertices in the mesh information are respectively 0,1,2, and 3, wherein the vertex coordinates are respectively: v0 (1, 0), V1 (-1, 0), V2 (1, -1, 0), V3 (-1, 0), these vertices may form a mesh as shown in FIG. 4.

In some embodiments, the adjustment of the three-dimensional GUI element to be adjusted is to adjust the grid information corresponding to the three-dimensional GUI element, and it can be known from the above description that the adjustment area may include a plurality of grids, so that the adjustment area is adjusted, and mainly, the grid information corresponding to the adjustment area is adjusted. As a way, the adjustment of the three-dimensional GUI element to be adjusted is mainly to adjust the spatial coordinates of the vertices included in the mesh information by adjusting parameters, so that the aspect ratio of the adjustment area of the three-dimensional GUI element to be adjusted can be changed. In this embodiment of the present application, the grid information may be centrally stored in a Meta file, where the Meta file is a file for assisting in managing model resources, different resources may be distinguished according to GUID (Global unique identifier, globally unique identifier) recorded in Meta, and Meta is also used to record some important resource information, such as information about an instructor of each resource, where the Meta file is essentially a text document, which is mainly generated using the format of YAML.

Step S150: and displaying the adjusted three-dimensional GUI element.

The terminal device adjusts grid information of the adjustment area according to the adjustment parameters, and can display the adjusted three-dimensional GUI element after obtaining the adjusted three-dimensional GUI element, wherein the position of the adjusted three-dimensional GUI element can be correspondingly adjusted along with the size of the three-dimensional GUI element after stretching or compressing operation.

According to the three-dimensional model adjustment method, the three-dimensional GUI element to be adjusted is adjusted by acquiring the cutting parameters and the adjustment parameters of the three-dimensional GUI element to be adjusted, and when the adjustment operation is executed, the embodiment of the application can ensure that only the adjustment area in the three-dimensional GUI element to be adjusted is adjusted, and the fixed area in the three-dimensional GUI element to be adjusted is not changed, so that the accuracy of three-dimensional GUI element adjustment can be improved, repeated modeling of the GUI element can be avoided, meanwhile, the efficiency of building the three-dimensional model can be improved, and the memory consumption of terminal equipment can be reduced to a certain extent.

Referring to fig. 5, another embodiment of the present application provides a three-dimensional model adjustment method, which is applied to a terminal device, and the method may include:

step S210: and acquiring cutting parameters of the GUI elements of the three-dimensional graphical user interface to be adjusted.

In some embodiments, the terminal device may acquire a cutting parameter input by a user for the three-dimensional GUI element to be adjusted, and use the cutting parameter as a cutting parameter corresponding to the three-dimensional GUI element to be adjusted. In other embodiments, the terminal device may also obtain a historical cutting parameter corresponding to the three-dimensional GUI element to be adjusted, and may use the historical cutting parameter as the cutting parameter corresponding to the three-dimensional GUI element to be adjusted.

Step S220: and cutting the three-dimensional GUI element to be adjusted into a plurality of areas according to the cutting parameters, and determining an adjustment area and a fixed area in the plurality of areas, wherein the fixed area is a corner area of the three-dimensional GUI element to be adjusted.

It can be appreciated from the above description that a plurality of cutting parameters may be input for the three-dimensional GUI element to be adjusted, and the cutting parameters may include a transverse cutting line, a longitudinal cutting line, an oblique cutting line, and the like, and the number of the cutting parameters may be different, as in fig. 3, the cutting parameters may include two transverse cutting lines and two longitudinal cutting lines. Since the acquisition of the transverse cutting line or the oblique cutting line is similar to the acquisition of the longitudinal cutting line, the embodiment of the present application only gives a case of how to acquire the longitudinal cutting line and how to treat the three-dimensional GUI element to be adjusted by the longitudinal cutting line, and the present application does not limit the number of the longitudinal cutting lines.

Step S220 may include steps S221 to S222 as shown in fig. 6.

Step S221: and when the first cutting line and the second cutting line are intersected with the three-dimensional GUI element to be adjusted, acquiring the intersection positions of the first cutting line and the second cutting line with the three-dimensional GUI element to be adjusted.

In some embodiments, the cutting parameters may include a first cutting line and a second cutting line, and when the terminal device obtains the cutting parameters of the three-dimensional GUI element to be adjusted, it may detect whether the first cutting line and the second cutting line in the cutting parameters intersect the three-dimensional GUI element to be adjusted, and if the first cutting line and the second cutting line intersect the three-dimensional GUI element to be adjusted, obtain positions where the first cutting line and the second cutting line intersect the three-dimensional GUI element to be adjusted. If the first cutting line and the second cutting line are not intersected with the three-dimensional GUI element to be adjusted, the terminal equipment indicates that the acquisition of the cutting parameters of the three-dimensional GUI element to be adjusted fails, as a way, the terminal equipment can prompt the user to input the cutting parameters again, if the terminal equipment still does not receive the cutting parameters input by the user within a preset time period, the terminal equipment can send out prompt information for inputting the cutting parameters again, in the process, the terminal equipment can record the prompt times, and when the prompt times are larger than the preset times, the terminal equipment indicates that the acquisition of the cutting parameters by the terminal equipment fails, and the terminal equipment ends the three-dimensional model adjustment operation.

In some embodiments, when detecting whether the first cutting line and the second cutting line intersect with the three-dimensional GUI element to be adjusted, the terminal device may first acquire the first cutting line and determine whether the first cutting line intersects with the three-dimensional GUI element to be adjusted, if the first cutting line intersects with the three-dimensional GUI element to be adjusted, the terminal device acquires the second cutting line and determine whether the second cutting line intersects with the three-dimensional GUI element to be adjusted, and if the second cutting line intersects with the three-dimensional GUI element to be adjusted, it indicates that the first cutting line and the second cutting line intersect with the three-dimensional GUI element to be adjusted. In other embodiments, the terminal device may also obtain the first cutting line and the second cutting line at the same time, and determine whether the first cutting line and the second cutting line are coincident, if the first cutting line is coincident with the second cutting line, then obtain one cutting line from any of the first cutting line and the second cutting line, and determine whether the cutting line intersects with the three-dimensional GUI element to be adjusted, if the cutting line intersects with the three-dimensional GUI element to be adjusted, then indicate that the first cutting line and the second cutting line intersect with the three-dimensional GUI element to be adjusted.
