Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a flowchart of steps of a method for scene switching according to an embodiment of the present invention, which may be executed by an electronic device such as a terminal device or a server, as shown in fig. 1, where the method may include:
The current scene may be a different application scene, such as a scene in a current room when the room is viewed in a panoramic manner. The screen origin generally refers to the top left corner vertex of the screen.
An object with a roaming point exists in the current scene, and a user can click the roaming point to switch the roaming effect. In a display interface of a current scene, when a user clicks a screen, acquiring a click coordinate of the user on the screen, and taking a vector from an origin of the screen to the click coordinate as a first vector.
After the click coordinate of the user on the screen is acquired and the first vector is determined, the roaming point in the current scene can be traversed according to the click coordinate and the first vector to determine a roaming point which has the minimum distance from the click coordinate and meets the preset condition as the optimal roaming point. Before traversing the roaming points in the current scene, firstly defining a roaming point variable, using the roaming point variable to record the optimal roaming point in the currently traversed roaming points, and initializing the value of the roaming point variable to be 0.
A roaming point may be randomly determined from all roaming points in the current scene, or a roaming point may be determined from all roaming points in the current scene according to the order of the roaming points, and the determined roaming point is used as the current roaming point. Since the roaming point is an object in the three-dimensional space of the current scene, the roaming point has a space coordinate in the three-dimensional space, and for convenience of calculation, the space coordinate of the current roaming point may be converted into a screen coordinate, and a vector from the screen origin to the screen coordinate of the current roaming point may be used as the second vector.
In an embodiment of the present invention, the converting the spatial coordinates of the current roaming point into the screen coordinates includes:
and taking the screen as a projection plane, and projecting the space coordinate of the current roaming point to the projection plane to obtain the screen coordinate of the current roaming point.
And determining the spatial coordinates of the current roaming point in the current scene. The method comprises the steps that a current scene is a virtual three-dimensional space, in a display interface of the three-dimensional space, a user can view images of the three-dimensional space at different angles by rotating a virtual camera, so that the display interface of the current scene corresponds to one rotation angle of the virtual camera, a screen is used as a projection plane according to the relation between the space coordinate of the three-dimensional space and the rotation angle of the virtual camera, the space coordinate of a current roaming point is projected and contracted to the projection plane, and the screen coordinate of the current roaming point is obtained. The screen coordinate is obtained by performing projection conversion on the space coordinate of the current roaming point, and the obtained screen coordinate is more accurate.
And 104, calculating an included angle between the first vector and the second vector, and calculating a distance between a click point corresponding to the click coordinate and a screen point corresponding to the screen coordinate.
The point multiplication calculation can be performed on the first vector and the second vector to obtain a cosine value of an included angle between the first vector and the second vector, and the cosine value is subjected to the inverse cosine calculation to obtain an included angle between the first vector and the second vector. Of course, other included angle calculation methods may be used to calculate the included angle between the first vector and the second vector.
And calculating the distance between the click point corresponding to the click coordinate and the screen point corresponding to the screen coordinate according to the click coordinate and the screen coordinate. For example, the click coordinate is (x)1,y1) Screen coordinates of (x)2,y2) Then the distance between the click point and the screen point is
And the screen point is a point corresponding to the current free-tour point on the screen.
And 105, judging whether the included angle and the distance meet preset conditions, if so, executing step 106, and if not, executing step 108.
The preset conditions simultaneously specify conditions required to be met by the included angle and conditions required to be met by the distance so as to determine roaming points within a certain range from the click coordinates.
In an embodiment of the present invention, the determining whether the included angle and the distance satisfy a preset condition includes: and judging whether the included angle is smaller than a preset included angle threshold value or not and the distance is smaller than a preset distance threshold value.
The preset included angle threshold value is equal to an included angle between a tangent line from a screen origin point to a circle and a second vector, the circle center of the circle is a screen point corresponding to the current roaming point, and the radius is the preset distance threshold value.
The preset included angle threshold value and the preset distance threshold value have a certain relation, namely, a circle which takes a screen point corresponding to the current roaming point as a circle center and takes the preset distance threshold value as a radius is determined, a tangent line from the original point of the screen to the circle is determined, the included angle between the tangent line and the second vector is calculated, and the obtained included angle is the preset included angle threshold value. When the determination is made, it is first determined whether the included angle is smaller than or equal to the preset included angle threshold, and if the included angle is smaller than or equal to the preset included angle threshold, it is further determined whether the distance is smaller than or equal to the preset distance threshold, if the distance is smaller than or equal to the preset distance threshold, step 106 may be executed, and if the distance is greater than the preset distance threshold or the included angle is greater than the preset included angle threshold, step 108 may be executed.
For example, fig. 2 is a schematic diagram of distribution of the screen points and the click points corresponding to the roaming points on the screen in the embodiment of the present invention, as shown in fig. 2, width is the screen width, height is the screen height, and point B (x) is1,y1) For the screen point corresponding to the current roaming point, the click point is A (x, y), the first vector is obtained as (x, y), and the second vector is obtained as (x, y)1,y1) The angle between the first vector and the second vector is an angle 2, and the screen point B (x) corresponding to the current roaming point is firstly used1,y1) Determining a circle by taking a preset distance threshold value as a radius, determining a tangent line from the original point (0,0) of the screen to the circle, calculating an included angle between the tangent line and a second vector, taking the obtained included angle as a preset included angle threshold value, taking the preset included angle threshold value as an angle 1, judging whether the angle 2 is less than or equal to the angle 1, obtaining that the angle 2 is less than the angle 1, and further judging a click point A (x, y) and a screen point B (x, y)1,y1) Whether the distance between the click point A and the screen point B is less than or equal to a preset distance threshold value is judged, and the click point A (x, y) and the screen point B (x) are clicked1,y1) The distance between them is less than a preset distance threshold.
And step 106, judging whether the distance is smaller than the distance between the value of the roaming point variable and the click point corresponding to the click coordinate, if so, executing step 107, and if not, executing step 108.
And when the included angle between the first vector and the second vector and the distance between the click point and the screen point meet preset conditions, further judging whether the distance is smaller than the distance between the value of the roaming point variable and the click point corresponding to the click coordinate to determine whether to update the value of the roaming point variable. When the distance is larger than the distance between the value of the roaming point variable and the click point corresponding to the click coordinate, the value of the roaming point variable does not need to be updated, and when the distance is smaller than the distance between the value of the roaming point variable and the click point corresponding to the click coordinate, the value of the roaming point variable is updated.
And 107, assigning the current roaming point to a roaming point variable.
And if the distance between the click point corresponding to the click coordinate and the screen point corresponding to the screen coordinate is less than the distance between the value of the roaming point variable and the click point corresponding to the click coordinate, indicating that the screen point corresponding to the current roaming point is closer to the click point, and assigning the current roaming point to the roaming point variable.
And 108, judging whether all the roaming points in the current scene are judged to be finished, if so, executing step 109, and if not, executing step 103.
After the judgment of the current roaming point is completed, whether all the roaming points in the current scene are judged to be completed or not is judged currently, if all the roaming points are judged to be completed, the circulating judgment is stopped, and if the roaming points which are not judged to be completed exist, the steps 103 to 108 are executed circularly until all the roaming points are judged to be completed.
For the judgment of this step, a loop variable may be set to record the number of currently traversed roaming points, and if the loop variable is initialized, the value of the loop variable is initialized to 0, after the judgment of the current roaming point is completed, it is judged whether the value of the loop variable is smaller than the total number of all roaming points in the current scene, if so, the value of the loop variable is added by 1, and step 103 is executed, if not, the loop is ended, and step 109 is executed.
And step 109, taking the value of the roaming point variable as an optimal roaming point, and switching the current scene to the scene corresponding to the optimal roaming point.
After all the roaming points in the current scene are judged, the obtained value of the roaming point variable records a roaming point closest to the click point, the roaming point is used as the optimal roaming point, the scene corresponding to the optimal roaming point is obtained, and the current scene is switched to the scene corresponding to the optimal roaming point.
In the method for switching scenes provided by this embodiment, after the click coordinate of the user on the screen is obtained, the vector from the screen origin to the click coordinate is used as a first vector, the spatial coordinate of the wandering point in the current scene is converted into the screen coordinate, the vector from the screen origin to the screen coordinate is used as a second vector, the roaming point where the included angle between the second vector and the first vector and the distance between the click coordinate and the screen coordinate satisfy the preset condition is selected as the optimal roaming point, and the switching of scenes is performed, that is, the switching of scenes can be performed when the click point is within a certain range of the roaming point without the click point being overlapped with the wandering point, so that the interactivity with the user is enhanced.
