Problems solved by technology

[0003] In related technologies, when using textures to render characters, especially faces, usually only the reflection and shadow of light are considered, and the light changes caused by subsurface scattering of light are not considered, so the face is relatively rigid and rigid. Therefore, the related technology 3D image simulation technology has the defect of low fidelity
[0004] For the above-mentioned problems existing in related technologies, no effective solution has been found yet

Abstract

The invention provides a character skin rendering method and device, a storage medium and an electronic device. The method comprises the steps that first mapping data of a face map of a virtual character on a pre-integration skin model and material information of the virtual character are acquired, and the material information is used for representing the sub-surface scattering state of the virtual character; second mapping data is generated according to the material information and the first mapping data; the facial map is rendered on a sub-surface scattering skin model using the second map data. The technical problem that the face of the virtual character is stiff and stiff in the prior art is solved, so that the face of the virtual character is more vivid, natural, flexible and real.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a rendering method and device, a storage medium, and an electronic device for a character's skin. Background technique [0002] In related technologies, with the development of computer graphics, people's pursuit of image fidelity is getting higher and higher. More and more real images can be described by using the technology of iconography, and the method of normal map can improve the fidelity of 3D image description. In the case of limited computer processing power or when rendering animation is limited by time, normal maps are also a better solution. Normal maps are mostly used in the rendering of CG animations and the production of game screens. Models with high details are mapped Bake the normal map, and then assign it to the normal map channel of the low-end model, so that the surface has the rendering effect of light and shadow distribution, which can greatly re...
