  • Method for simulating hair using particle emissions
    Patent number: 5777619
    Abstract: A method for simulating and rendering hair. A simulator calculates the motion dynamics of a hair. The simulator includes a particle system that emits particles from a surface and a normalization module that normalizes the trajectory of each of the particles to a fixed length to form a set of normalized segments. The simulator outputs a list of normalized segments that are passed to a renderer. The renderer performs a variety of tasks, including fuzzy segment generation and self-shadowing, that results in an image being displayed on a display device. That is, the renderer takes three-dimensional spacial information, applies a light to this information and renders this information as a two-dimensional image.
