Fig. 4 is a schematic flow chart of a model detection method according to an embodiment of the present invention, and as shown in fig. 4, the step of detecting the virtual object model by using at least one preset constraint condition in S101 to obtain a detection result may include:
s401, determining the normal direction of each triangle according to the drawing sequence of the vertexes of each triangle in the virtual object model by adopting a normal overturning constraint condition.
If the vertex drawing orders of all the triangles are all anticlockwise or clockwise, the normal directions of all the triangles are the same direction.
In some embodiments, the terminal may adopt a normal inversion constraint condition, calculate a cross product result of two adjacent edges of each triangle according to a vertex drawing sequence of the triangle, and determine a normal direction of each triangle according to the cross product result; if the two triangles are triangles with a common side, the terminal can determine the drawing sequence of the common side according to the drawing sequence of the vertexes of the triangles, and then determine the normal direction of each triangle.
It should be noted that there may be points with very close distances in the virtual object model making process, and such points may split two adjacent triangles into two non-adjacent triangles, which may cause skipping of detection of the two triangles during detection, resulting in an error in the result. Therefore, the vertexes need to be combined into the same vertex initially, and the accuracy of the result is guaranteed.

In the embodiment of the application, if the normal directions of the triangles are not consistent, the problem of die penetration can occur, when the normal directions of some triangles face outwards, correct blocking can be realized, and when the normal directions of some triangles face inwards, correct blocking cannot be realized, so that the die penetration is caused. Also, the normal orientation of the triangle is illumination dependent. Triangles with the normal lines facing the right directions can be normally illuminated by light, and triangle rows with the normal lines facing the wrong directions cannot be illuminated by light, so that display errors occur, and the situation of threading exists.
Optionally, the at least one constraint includes: an overlap constraint. Fig. 5 is a schematic flow chart of a model detection method according to an embodiment of the present invention, and as shown in fig. 5, the step of detecting the virtual object model by using at least one preset constraint condition in S101 to obtain a detection result may include:

It should be noted that the time complexity of the algorithm of the above-mentioned processes from S501 to S504 is O (n ^2), and the implementation process of the algorithm also adopts c + +.
Optionally, the at least one constraint includes: same plane constraint conditions; fig. 6 is a schematic flow chart of a model detection method according to an embodiment of the present invention, and as shown in fig. 6, the step of detecting the virtual object model by using at least one preset constraint condition in S101 to obtain a detection result may include:
s601, determining triangles corresponding to all planes in the virtual object model by adopting the same plane constraint condition.

And S603, if the target plane is not the preset threshold, indicating that the triangles in the target plane in the virtual object model are not in the same plane by the indicating information.
In practical application, the model is constructed in 3DS MAX, and more modes of polygons are used, so that in the manufacturing process, under the condition of some misoperation of polygons, split triangles are not in the same plane, and therefore whether triangles of each plane are in the same plane needs to be separately detected, and when the triangles of each plane are not in the same plane, the situation of mode crossing occurs with probability.
In some embodiments, the terminal calculates normal data of each triangle in the same target plane, performs normalization processing on the normal data to obtain normalized normal data, calculates a dot product of the normalized normal data of the triangles in the same target plane, and determines whether the dot product is a preset threshold, and if not, the indication information indicates that the triangles in the target plane in the virtual object model are not in the same plane.

s701, determining the area of a first surrounding box of a rendering model of the virtual object model and the area of a second surrounding box of a collision body model of the virtual object model by adopting the virtual object model and the collision body constraint conditions.
S702, judging whether the ratio of the area of the first surrounding box to the area of the second surrounding box is within a preset range.
S703, if not, indicating that the sizes of the rendering model and the collision body model have errors by the indication information.
The virtual object model can be split into a rendering model and a collision body model, the number of the faces of the collision body model is far smaller than that of the rendering model, the collision body model is an invisible object in a game, and the movement of a virtual character is blocked and limited, so that the sizes of the virtual object model and the collision body model are required to be ensured, and the shapes of the virtual object model and the collision body model are almost consistent.
In some embodiments, the terminal may calculate the first enclosure box area and the second enclosure box area for the three views, respectively, that is, calculate the first enclosure box area and the second enclosure box area for the front view, the top view, and the side view, respectively, calculate a first ratio of the first enclosure box area and the second enclosure box area of the front view, a second ratio of the first enclosure box area and the second enclosure box area of the top view, and a third ratio of the first enclosure box area and the second enclosure box area of the side view; if the first ratio, the second ratio and the third ratio are all within a preset range, the indication information indicates that no error exists in the sizes of the rendering model and the collision body model; if any ratio of the first ratio, the second ratio and the third ratio is not in a preset range, the indication information indicates that errors exist in sizes of the rendering model and the collision body model.
