We are happy to announce that the Disney Ptex library has been released as open source under the BSD license. The Ptex library is the same production-proven code used at Disney and included with Pixar’s PRMan, and includes full support for reading, writing, caching, and filtering Ptex texture files.

We have set up a discussion group at http://groups.google.com/group/ptex
along with a related http://groups.google.com/group/ptex-announce group.
We encourage your comments and questions.

We expect to follow Ptex with other open source projects that we hope
the community will find beneficial. We will soon be launching a new
Walt Disney Animation Studios Technology page under
http://disneyanimation.com. It will include links to our open source
projects as will as a library of recent publications.

An additional announcement will be sent when the Technology site goes
live. All further announcements will be made to the ptexannounce
group.

Thanks for your interest!

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. <LI class=pad>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.
