Title:
HIGHLIGHT RENDERING METHOD AND APPARATUS, MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/197860
Kind Code:
A1
Abstract:
The present invention relates to a highlight rendering method and apparatus, a medium, and an electronic device. The method comprises: obtaining a highlight image to be rendered, and drawing, in the highlight image, a highlight shape to be rendered; according to a light source direction in a world space, determining a light source vector in a target coordinate space corresponding to a hair model; for each pixel point to be rendered in the hair model, according to a sight line direction in the world space, determining a sight line vector corresponding to the pixel point in the target coordinate space; for each pixel point, according to the light source vector and the sight line vector corresponding to the pixel point, determining a texture offset of the pixel point in a vertical direction corresponding to a horizontal direction in the highlight image; and sampling from the highlight image according to the texture offset corresponding to each pixel point so as to render the pixel points to obtain a rendered highlight rendered image. Therefore, a rendering effect of anisotropic highlight can be achieved while the highlight shape of rendering is ensured.
