Document Type and Number:
WIPO Patent Application WO/2023/098344
Kind Code:
A1
Abstract:
The present disclosure provides a graphic processing method and apparatus, a computer device, and a storage medium. The method comprises: obtaining a texture map used for rendering a target three-dimensional model, the texture map comprising a color map, a normal map reflecting a normal direction, and a brush map reflecting brush drawing characteristics; performing illumination processing on the normal map on the basis of preset illumination direction information to obtain a normal map subjected to illumination processing; performing first sampling processing on the normal map subjected to illumination processing, the color map and the brush map to obtain a first sampling layer; in response to input contour line information of the target three-dimensional model, performing contour stroke processing on the first sampling layer on the basis of the contour line information to obtain a second sampling layer; and rendering the target three-dimensional model on the basis of the second sampling layer to obtain a rendered target three-dimensional model. According to the embodiments of the present disclosure, the rendered target three-dimensional model is more vivid and closer to the watercolor drawing effect.
