Texture mapping using a plane normal to a selected triangle and using a (U,V) origin thereof to preserve texture size upon surface scaling

摘要

A method, apparatus and article of manufacture for (U,V) texture mapping of object surfaces in a 3D graphics system in such a way that the size of the texture is preserved, and the texture wraps around curved surfaces, even when the surface is scaled. One or more triangles are selected from an arbitrary mesh of triangles. A plane normal and a (U, V) origin of the plane normal is determined for each selected triangle. The surface of the selected triangle is texture mapped using the plane normal and the (U,V) origin.
