Abstract

The present application relates to a hair rendering method, device, electronic device and storage medium, and belongs to the technical field of computer graphics. The method includes: acquiring a plurality of initial sections, the plurality of initial sections being used for simulating the cross sections of hair growth; according to the rule that the hair distribution density decreases in turn, determining the hair on each initial section in the plurality of initial sections Distributing points to obtain a plurality of hair sections; through the preset lighting model, the multiple hair sections are sequentially rendered on the three-dimensional model of the hair to be drawn to obtain a target three-dimensional model, and the preset lighting model is used to simulate the lighting effect of the hair . The present application can provide a simple and efficient hair rendering method, which improves the efficiency of hair rendering and has lower performance requirements for rendering devices.

Description

technical field [0001] The present application relates to the technical field of computer graphics, and in particular to a hair rendering method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of computer graphics technology, more and more virtual objects are used in the production of movies, games and animations. In order to realize the realism of virtual objects, some key technologies are needed, such as skeletal animation, facial expression and hair simulation, etc., and hair simulation has always been a very challenging and important problem in the field of graphics. Hair rendering refers to drawing hair for virtual objects and realizing the simulation of hair, which plays an important role in improving the realism of virtual objects. [0003] In the related art, a hair rendering method is provided, which includes: for a 3D model of hair to be drawn, performing refined geometric modeling for each hair of the 3D ...
