The invention provides a scene model surface texture superposition method and device based on collision detection, and the method comprises the steps: transmitting a ray to a scene model, and generating a projection body capable of covering the surface of the scene model through collision detection; respectively calculating the position of a camera and the direction of a ray in the model space, and transmitting the positions and the directions into a fragment shader; in the fragment shader, texture superposition is carried out on the surface of the module according to the depth value, the coordinate value of the camera position and the ray direction, the calculation amount is reduced, the texture superposition effect is good, and the authenticity is high.
Description
technical field [0001] The invention relates to the field of computer graphics, in particular to a method and device for superimposing surface textures of a scene model based on collision detection. Background technique [0002] In the process of superimposing the surface texture of the existing scene model, not only a large amount of calculation is required, but also the complexity is high, and the display effect after the texture is superimposed is poor. [0003] Therefore, there is a need for a method and device for superimposing the surface texture of a scene model based on collision detection, which can reduce the amount of calculation and has high authenticity. SUMMARY OF THE INVENTION [0004] (1) Technical problems to be solved [0005] In order to solve the above problems of the prior art, the present invention provides a method and device for superimposing surface textures of a scene model based on collision detection, which can reduce the amount of calculation ...
