Embodiment Construction
[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] The shadow rendering method in the virtual home improvement interior scene design of the present invention first determines the depth values of all visible pixels in the home improvement interior scene under the camera position angle of view and stores them in the texture cache, builds and generates shadow maps on this basis, and then searches for textures Cache, find all pixels closer to the light source than the current pixel in the neighborhood of the current pixel, and calculate their average depth distance, and then determine the blocking area of the current pixel according to the average depth distance and the size of the light source , and then estimate the penumbra measurement width, and then perform Poisson disk sampling on the shadow map, and perform percentage progressive filtering on each pixel obtained from the sa...
