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.")
