Abstract
In various embodiments, a cloth weave structure is built from curves over the surface of a subdivision mesh at rendertime. A coherent woven or knitted surface is generated from interwoven curve geometry and a subdivision (or polygon) mesh. In one aspect, this is done at render-time. Accordingly, in one embodiment, a geometry generation process takes an ST map as input to control the direction of flow of curves (yarns) over the surface. Since each face is calculated independently, general global coordinates in ST space are predefined (at the beginning of the render) to make sure that each face transitions smoothly to the next.
