Problems solved by technology

At present, in order to obtain this kind of rendering effect, Blinn-Phong and BRDF are generally used to process the light and shade rendering effect of the model, so the rendered effect has poor drawing accuracy and the picture effect is unreal
[0004] In the process of realizing the present invention, the inventor found that there are at least defects in the prior art such as difficult rendering, poor drawing precision and unreal picture effects

Embodiment Construction

[0047] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0048] In order to solve the problems existing in the prior art, according to the embodiment of the present invention, such as Figure 1-Figure 4 As shown, a method of simulating the real skin of a person based on subsurface scattering in screen space is provided, that is, a SSSSS (Screen Space Sub Surface Scattering) is proposed based on subsurface scattering, and the rendering effect is better than the current rendering effect. Significant improvements, especially in the rendering of skin objects.

[0049] In 3D graphics, it is necessary to map the real 3D model from the texture space to the screen space, such as: decorative patterns on the walls of buildings, woo...

Abstract

The invention discloses a screen-space-based method for simulating the real skin of a figure through sub-surface scattering. The method mainly includes the steps of conducting filtration and screening on a finger skin object to be rendered and other objects in a scene; rendering the skin of the figure first time to obtain Alpha mixing to obtain a mixed image; rendering the scene second time to obtain a semi-transparent effect image for a thinner part of the skin; stacking the semi-transparent image with the mixed image to obtain a final rendering effect image. By means of the screen-space-based method for simulating the real skin of the figure through sub-surface scattering, the shortcomings that in the prior art, the rendering difficulty is large, the drawing accuracy is poor and the image effect is untruthful can be overcome; the screen-space-based method has the advantages of being small in rendering difficulty, good in drawing accuracy and real in image effect.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method for simulating real skin of a person based on subsurface scattering in screen space. Background technique [0002] With the development of computer graphics, people's cognition of the virtual three-dimensional world is enhanced, and the rendering technology of higher and higher picture quality is applied to the game. The rendering technology of real character skin has always been the researcher's requirement To solve the difficult problem, the present invention utilizes a subsurface scattering method implemented by DX9 application program to solve the above problem and achieve good rendering effect. [0003] Sub Surface Scattering (SSS for short) is a phenomenon in which light is scattered internally after entering a non-metallic material, and finally exits the object and enters the field of view. This kind of scattering makes the overall effect of lighting sof...
