Abstract
Methods are disclosed for the computer generation of data for images that include hair, fur, or other strand-like material. A volume for the hair is specified, having a plurality of surfaces. A fluid flow simulation is performed within the volume, with a first surface of the volume being a source area through which fluid is simulated to enter the volume, and a second surface being an exit surface through which fluid is simulated as exiting the volume. The fluid flow simulation may be used to produce fluid flow lines, such as from a velocity vector field for the fluid. Fluid flow lines are selected, and image data of hairs that follow the fluid flow lines are generated. Other embodiments include generating animation sequences by generating images wherein the volume and surfaces vary between frames.
