Title:
HAIR RENDERING METHOD, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/019788
Kind Code:
A1
Abstract:
Disclosed in the present invention are a hair rendering method, and a device and a storage medium. In a preprocessing stage of rendering, multi-layer hair models can be obtained by copying a model of a target object to be subjected to hair brushing, the multi-layer hair models are merged, and then rendering is performed. In order to achieve the layering of hairs by performing rendering on a merged model, vertex colors can be set for the multi-layer hair models, and the vertex colors are in a positive correlation with offsets of the multi-layer hair models. In a rendering stage, a rendering engine can execute a rendering operation on vertexes in the merged model according to the vertex colors of the multi-layer hair models, and execute an offset operation in a normal direction on vertexes at the same location in a target model according to the offsets associated with the vertex colors of the multi-layer hair models. In this embodiment, a rendering operation and an offset operation are performed on a merged model, such that the effect of performing rendering on multi-layer hair models can be achieved, thereby greatly reducing the requirements on computing resources in a rendering process, and improving the rendering efficiency.
