Ishair: Importance Sampling For Hair Scattering

View page
US Patent:
20130215139, Aug 22, 2013
Filed:
Jan 17, 2013
Appl. No.:
13/743775
Inventors:
Pacific Data Images LLC - , US
Jiawei OU - Hanover NH, US
Assignee:
Pacific Data Images LLC - Redwood City CA
International Classification:
G06T 11/00
US Classification:
345595
Abstract:
A technique for rendering an image of hair in a computer-generated scene is described. The scene includes a virtual light source and a hair virtual object comprising a material model. A hair shading function partly defining the material model is accessed. A set of random values is generated. The hair shading function is importance sampled by converting the set of random values into a set of light direction samples based on a Cauchy distribution. The probability density function of each converted light direction sample uses a Cauchy distribution. A light color value and a hair color value are computed for each light direction sample of the set of light direction samples. The light color values and the hair color values are weighted to determine a set of weighted values. A characteristic of a pixel representing part of the virtual object is determined based on the set of weighted values.
