Official Announcement as posted on Monophyl.com.
“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.
The Ptex home page is located at http://ptex.us, and the source code is hosted at http://github.com/wdas/ptex/.
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!
