Disney releases Ptex API as open source

[Ted Gocek]

On Jan 15 Walt Disney Animation Studios released their Ptex API as
open source. The first announcment was made here - http://monophyl.com/?p=640.

==========================================================
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.

===========================================================
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!

WOW I would love to get my hands on that!!
I'm a little unclear as to how it's implemented however? It would have
to supported by the renderer and modelling environment correct, but
what packages supports this and how is it represented in RIB?
