  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.
