RENDERING HAIR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18605513 titled 'RENDERING HAIR
In a method described in the patent application, various characteristics of a pixel in a hair area of a virtual image are analyzed to determine the scattering amounts corresponding to different optical paths of a virtual main light source. These scattering amounts are then used to calculate the coloring information of the pixel under the influence of the virtual main light source.
- Longitudinal angle, azimuthal angle, illumination information, and color information of a pixel in a hair area of a virtual image are obtained.
- Scattering amounts are determined based on the longitudinal and azimuthal angles, illumination information, and color information of the pixel.
- The scattering amounts corresponding to different optical paths of the virtual main light source are fused to obtain the final coloring information of the pixel.
Potential Applications: - Virtual reality and augmented reality applications - Computer graphics and animation software - Lighting design and simulation tools
Problems Solved: - Accurately simulating the interaction of light with hair in virtual environments - Enhancing the realism of virtual images and animations

Original Abstract Submitted
In a method, a longitudinal angle, an azimuthal angle, illumination information, and color information of a pixel in a hair area of a virtual image corresponding to each optical path of a virtual main light source are obtained. For each optical path of the virtual main light source, a respective longitudinal scattering amount is determined based on the longitudinal angle and the illumination information of the pixel, a respective azimuthal scattering amount is determined based on the azimuthal angle of the pixel, and a respective scattering amount of the pixel corresponding to the respective optical path is determined according to the longitudinal scattering amount, the azimuthal scattering amount, and the color information of the pixel. Scattering amounts of the pixel corresponding to the optical paths of the virtual main light source are fused to obtain first coloring information of the pixel corresponding to the virtual main light source.
