Abstract

The invention relates to the field of image rendering, and provides a virtual hair processing method and device, terminal equipment and a readable storage medium. The method comprises the following steps: acquiring world position coordinates of a coloring point on virtual hair, a light source position and a sight line position; determining an illumination direction vector and a line-of-sight direction vector of the coloring point; calculating a half-angle direction vector of an included angle between the illumination direction and the sight line direction; calculating the differential of the world position coordinate of the coloring point in the V direction in the UV coordinate system to obtain a similar tangent direction vector of the coloring point; according to a dot product operation result of the tangent-like direction vector and the half-angle direction vector, the highlight brightness of the coloring point is determined; and rendering the virtual hair according to the highlight brightness. According to the method, the differential of the world position coordinate of the coloring point in the V direction in the UV coordinate system is used for replacing the tangential direction vector of the coloring point, so that the highlight brightness is simply and quickly obtained, and a better highlight effect can be obtained by processing virtual hair.

Description

technical field [0001] The invention relates to the field of image rendering, in particular to a virtual hair processing method. The present invention also relates to a virtual hair processing device, a terminal device and a computer-readable storage medium. Background technique [0002] When making the hair of game characters, usually such as figure 1 geometry hair as shown instead of figure 2 Realistic hair strands shown, this improves the rendering speed of the game. [0003] At present, some common offline renderers, such as Arnold renderer, its default shader can only produce effects for real hair, which is very unfriendly to geometric hair, and it is almost impossible to match the highlight effect of hair in the game, while using other materials The hair highlight effect produced by the ball is also not ideal. Contents of the invention [0004] The present invention provides a virtual hair processing method, device, terminal equipment and readable storage medium...
