Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In addition, it should be noted that, in the process of traditional hand-drawing style material mapping, the SP fills the layer first, and then controls the display range of the layer through masking, or performs drawing in cooperation with a brush pen in an empty layer to obtain the mapping.
Specifically, the SP first establishes a basic volume relationship of the virtual model in a form of superimposing a plurality of monochromatic image layers and a mask, for example, in the image layer diagram of the SP shown in fig. 1, the SP superimposes 5 image layers to obtain the volume relationship of the virtual model. Then, the SP superimposes the three layers shown in fig. 2 to realize the edge wear effect of the virtual model, and superimposes the two layers shown in fig. 3 to realize the texture of the virtual model and the production of random color patches to enrich the colors of the virtual model. Finally, the hand-drawn feeling and the rich detail expression are increased by the multiple hand-drawn layers shown in fig. 4.
However, the above method for making a map has the following disadvantages:
(1) the manufacturing efficiency is low. The method for making the chartlet needs to use a large number of masks and generators, and because the material has writing property and the masks have randomness, the method is often applied to writing items and is not suitable for the style of hand-drawing effect between cartoon and writing. At present, the style of the hand-drawing effect is realized by using a manual drawing mode, the manufacturing efficiency of materials with the hand-drawing style is reduced, and the programming advantage of the SP cannot be well utilized.
(2) The document is bloated. In the process of using SP to make a map, a large number of layers are usually used, for example, each layer controls a color, and the purpose of enriching the material performance is achieved by controlling the superposition between the mask under each layer and each layer. The programmed mask of the SP cannot directly meet the requirements of the hand-drawing style material, so that the hand-drawing style of the material is usually realized by a pure hand-drawing mode in practical application. With the increase of the number of layers and the increase of the hand-drawn mask, the map file becomes more and more bloated, so that the map file is too large, the whole process of map making becomes unsmooth, and the efficiency of map making is further influenced.
(3) The normalization is poor. Different art workers have different ways of making the pictures, so that the layers used in the process of making the pictures are different, and the standardization of the material files is poor.
(4) The modification is troublesome. Due to the increase of the number of layers and the use of a large amount of hand-drawn masks, the standardization of the whole material manufacturing is poor, and therefore the modification efficiency of the material is reduced.
(5) The overwrap management is inconvenient. The existing method for manufacturing the paste chart has the problems, so that the cost for communication and cooperation between the art personnel and the outside is inevitably increased, and the external packing management is unchanged.
To solve the above problems of the prior art, according to the embodiment of the present invention, a method for generating a texture map is provided, it should be noted that the steps shown in the flowchart of the figure can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from the order shown.
In addition, it should be further noted that an electronic device may be used as an execution subject of the method provided in this embodiment, where the electronic device may be, but is not limited to, a handheld device (e.g., a smartphone, a smart tablet, etc.), a non-handheld device (e.g., a computer device, etc.). Optionally, an application or program for creating the map is installed in the electronic device, for example, sd (substance designer) software and sp (substance designer) software.
FIG. 5 is a flowchart of a method for generating a texture map according to an embodiment of the present invention, as shown in FIG. 5, the method includes the following steps:
step S502, a parameter file corresponding to a material file of a preset material type is obtained.
In step S502, the preset material types may be, but are not limited to, a hand-drawing material type, a realistic material type, and a cartoon material type. The hand-painted material type is a hand-painted material, and the hand-painted material is an artistic expression, which is derived from the processing manner of painting, for example, the hand-painted pen touch in oil painting is an important component in painting with impression. The hand-drawing expression effect can be obtained by performing hand processing on the aspects of the outer contour, the virtual-real contrast, the color, the random brush stroke and the like.
In an alternative embodiment, material files of different material types correspond to different parameter files. The user can determine the material file for performing model rendering on the model to be rendered according to actual requirements, and further determine the parameter file required for generating the material map according to the material type to which the material file belongs. Optionally, the model to be rendered may be a game character in a game, or may also be a virtual model in the game, for example, a mountain, a tree, a house, or the like.
Optionally, the SD software may generate parameter files corresponding to material files of different material types, and the local memory of the electronic device may store an association relationship between the material types and the material files, so that when a user generates a material map through the SP software, the electronic device may call the parameter files corresponding to the material types according to the material types of the material files, for example, in the graphical user interface shown in fig. 6, the user may select the material types, so that the SP software may call the parameter files corresponding to the material types selected by the user, and further, the initial material map may be generated according to the initial parameters of the parameter files.
In the process, the parameter file contains the material parameters for generating the material file, and the user can adjust the material map corresponding to the model to be rendered only by adjusting the material parameters corresponding to the parameter file without modifying the mask or the generator, so that the modification efficiency of the material map is improved.
It should be noted that, as shown in step S502, the application can implement the making and modifying of the material file of the hand-drawn material type by adjusting the parameter file of the material file, and does not need to use a large number of layers and hand-drawn masks, thereby improving the generation efficiency and modification efficiency of the material file of the hand-drawn material type.
In addition, the material parameters corresponding to the parameter file may include, but are not limited to, color information, lighting angle, color block contrast, color block freehand drawing stylized intensity, and the like. Namely, the user can adjust the material quality parameter of the parameter file to achieve the adjustment of the material quality mapping corresponding to the model to be rendered.
Step S504, receiving an adjustment instruction, and adjusting the material parameter corresponding to the parameter file to obtain the adjusted material parameter.
In an alternative embodiment, the user may adjust the material parameters of the parameter file through the SP software in the electronic device. For example, the graphic user interface of the electronic device shown in fig. 7 shows layers corresponding to the parameter file, where "highlight" corresponds to a highlight layer, and "base _ fabric" corresponds to a base layer.
It should be noted that, the electronic device can adjust the material parameters in the parameter file according to the adjustment instruction initiated by the user, which is convenient and fast.
In step S506, a material map is generated based on the adjusted material parameters.
Based on the solutions defined in the foregoing steps S502 to S506, it can be known that, in the embodiment of the present invention, a manner of generating a material map based on the material parameters in the parameter file is adopted, and after the parameter file corresponding to the material file of the preset material type is obtained, an adjustment instruction is received to adjust the material parameters corresponding to the parameter file, so as to obtain the adjusted material parameters, and then the material map is generated based on the adjusted material parameters. The parameter file comprises material parameters for generating the material file.
It is easy to notice that in the above process, no mask and generator are needed in the process of generating the material map, so that the generation of the maps of the hand-drawn stylized material types with different stylization degrees can be met, the types of the material map are not limited to the cartoon type and the realistic writing type, the material map can be the hand-drawn type between the cartoon type and the realistic writing type, and the material types of the material map are enriched. In addition, because the parameter file contains the material parameters for generating the material file, the user only needs to adjust the material parameters to perfect the material map, thereby not only improving the manufacturing efficiency of the material map, but also improving the modification efficiency of the material map.
Therefore, the scheme provided by the application achieves the purpose of improving the manufacturing efficiency of the material map, the technical effect of improving the generation efficiency of the material map is achieved, and the technical problem of low manufacturing efficiency of the material map in the related technology is solved.
In an optional embodiment, before receiving the adjustment instruction and adjusting the material parameters corresponding to the parameter file to obtain the adjusted material parameters, the electronic device first obtains the initial material parameters corresponding to the parameter file, and generates the initial material map based on the initial material parameters.
Optionally, after the user selects the parameter file corresponding to the material map through the electronic device, the SP software in the electronic device generates the initial material map according to the parameter value corresponding to the initial material parameter in the parameter file. It should be noted that the initial material map generated by the initial material parameters in the parameter file may not meet the user requirements, that is, the rendering effect obtained by rendering the model to be rendered by using the initial material map cannot meet the user requirements, and in this scenario, the user may adjust the material parameters in the parameter file by using the electronic device, so that the material map generated by the adjusted material parameters can meet the user requirements.
Specifically, the electronic device determines a material parameter to be adjusted corresponding to the parameter file and a parameter value corresponding to the material parameter to be adjusted according to the model to be rendered, and adjusts the material parameter to be adjusted based on the parameter value to obtain an adjusted material parameter.
Optionally, the user may determine whether to adjust the material parameter corresponding to the material file according to the color information and the illumination information of the model to be rendered. If the color information, the light and shadow information, the illumination information and the like of the model to be rendered meet the requirements of the user, the user does not need to adjust the material parameters; if the color information, the light and shadow information, the illumination information and the like of the model to be rendered do not meet the requirements of the user, the user can adjust the material parameters corresponding to the material file through the SP software. For example, the user may adjust the material parameters shown in fig. 8 through SP software in the electronic device, where in fig. 8, base, grunge01, grunge02, shadow, top, light, reflection, ao, deepine, and the like represent different charts, and each chart is expanded to obtain the corresponding material parameters under each chart, and for example, when the user clicks the shadow chart in fig. 8, the electronic device may display the material parameters (e.g., color block color, color block range, and the like) included in the shadow chart shown in fig. 9.
It should be noted that the parameter file provides the user with the material parameters capable of adjusting the material mapping, and provides the user with the freedom of operation, thereby meeting the requirements of different virtual models on the material mapping to the maximum extent. Moreover, the user can freely adjust the light angle of the virtual model through the parameter file so as to meet the light and shadow expression of different shapes of the virtual model.
In an optional embodiment, before adjusting the material parameter corresponding to the parameter file, the electronic device first needs to obtain the parameter file corresponding to the material file of the preset material type. The electronic device can make the parameter file through SD software. Specifically, the electronic device determines the volume relationship of the model to be rendered according to the space coordinate information of the model to be rendered to obtain a volume parameter, determines the color information of the model to be rendered to obtain a color parameter, then determines the structure information and the light and shadow information of the model to be rendered, and finally generates a parameter file based on the volume parameter, the color parameter, the structure information and the light and shadow information. Wherein the light and shadow information at least comprises: the structure information of the illumination parameter of the model to be rendered at least comprises one of the following information: the model rendering method comprises the steps of obtaining light and shade information of a model to be rendered, three-dimensional hierarchical information of the model to be rendered and target highlight information of the model to be rendered.
In the process of determining the volume relation of the model to be rendered according to the model structure information corresponding to the model to be rendered and obtaining the volume parameter, the electronic equipment obtains a position map corresponding to the model to be rendered and obtains an environment mask map corresponding to the model to be rendered, and then the position map and the environment mask map are mixed to obtain the volume parameter. The position map at least comprises data information of color gradient gradual change of the model to be rendered according to a preset direction; the environment mask map at least comprises illumination information corresponding to the distance between the preset light source and the model to be rendered.
It should be noted that the position map corresponding to the model to be rendered represents the overall gradient relationship from bottom to top in the map corresponding to the model to be rendered. The environment mask map (a 0 map for short) can simulate shadows generated by a model to be rendered, and the volume of the model to be rendered can be increased by using the environment mask map when no light is applied, that is, light is not considered at all, and the environment mask map can simulate the effect of real illumination based on the phenomenon that the closer the light source is to the model to be rendered, the weaker the illumination of reflected light is.
In addition, it should be noted that after the world normal and the environmental mask map corresponding to the model to be rendered are obtained, the electronic device may perform a blending process on the position map and the environmental mask map, so as to obtain a black-white-gray relationship (i.e., the above-mentioned volume relationship) corresponding to the material map. The SD software is opened with three levels of black, white and gray colors, so that a user can adjust the basic color of the texture map in the SP software.
Optionally, in the basic volume parameter interface shown in fig. 10, the overall volume relationship and the color relationship corresponding to the model to be rendered may be made by setting a color, where color01 corresponds to a dark portion color, color02 corresponds to a gray scale color, and color03 corresponds to a bright portion color. Fig. 11 is a mapping effect obtained after rendering the model to be rendered based on the volume parameter.
In an optional embodiment, in the process of determining the color information of the model to be rendered and obtaining the color parameter, the electronic device first determines first color information of the model to be rendered, performs superposition processing on the color information corresponding to the volume parameter and the first color information to obtain second color information, then determines a normal direction of a surface normal of the model to be rendered from the normal map, and determines third color information of the model to be rendered according to the normal direction.

It should be noted that, in practical applications, the electronic device may select different color block materials from the SP software to meet practical requirements, for example, a user may select a color block style actually required from the color block materials shown in fig. 12 by the SP software to perform color superposition processing. Fig. 13 is a diagram of the random color patch effect obtained based on the above functional operations.

In contrast, the height map is off-block and the curvature map is linear. The part is divided into three switchable levels for the user to select, namely AO level (based on AO picture), concave shape 01 (based on height picture) and concave shape 02 (based on curvature picture). Fig. 21 shows a mapping effect obtained after rendering the model to be rendered based on the above-mentioned concave modeling parameters.
Optionally, the electronic device may combine the normal rotation height map with the curvature map to generate a thicker and heavier wear effect map that conforms to the hand-drawn style. Fig. 22 shows a mapping effect obtained after rendering the model to be rendered based on the edge wear parameters.

In the process of generating the parameter file, the SD software opens a range parameter, an edge hardness parameter, a deformation strength parameter and the like for a user to adjust in the SP software so as to adjust the surface height information of the model to be rendered. Fig. 23 shows a mapping effect obtained after rendering a model to be rendered based on the above-mentioned surface highlight information.
Optionally, the electronic device may add a light node to the world normal to generate punctate highlight information corresponding to the model to be rendered. Fig. 24 shows a mapping effect obtained after rendering the model to be rendered based on the dotted highlight information.
