Abstract

The invention discloses a physical method based on environment mapping for simulating human skin subsurface scattering. The method comprises steps that, a legendre formula is utilized to project and disintegrate an illumination integration equation in a to-be-simulated scene to acquire a luminance value of each pixel; the luminance value of each pixel is multiplied with an overflow color value to acquire a scattering value of each pixel at a back light face. The physical method based on environment mapping for simulating human skin subsurface scattering solves problems of large data processing workload, large occupation storage space and low processing efficiency existing in the prior art and has advantages of small data processing workload, small occupation storage space and high processing efficiency.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a physical method for simulating subsurface scattering of human skin based on environment maps. Background technique [0002] With the expansion of computer graphics and programmable technology, people have a stronger sense of cognition of the virtual three-dimensional world, and the rendering technology that requires picture quality is applied to the game. For the virtual scene, all creatures will be affected by the surrounding environment according to different materials. Direct or indirect lighting, resulting in different lighting effects. [0003] Subsurface Scattering (3S for short) mainly simulates a real light and shadow effect in the interior of not completely transparent materials, such as: candles, jade, marble, etc., which are most obvious. This kind of transparency has characteristics from the edge of the model to the model The trend of decreasing center, which also ...
