Ptex is a texture mapping system developed by Walt Disney Animation Studios for
production-quality rendering:
- No UV assignment is required! Ptex applies a separate texture to each face
of a subdivision or polygon mesh.
- The Ptex file format can efficiently store hundreds of thousands of texture
images in a single file.
- The Ptex API provides cached file I/O and high-quality filtering, everything
that is needed to easily add Ptex support to a production-quality renderer
or texture authoring application.
