  • WDAS' Ptex library released

    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
    along with a related 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 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

    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.
    Jan 15, 2010 Ptex released as free open source.
    Sep 30, 2009 Ptex integrated into Pixar's RenderMan Pro Server 15.0.
    Nov 21, 2008 Disney's Bolt released; first feature film to use Ptex.
    Jun 24, 2008 Ptex presented at Eurographics Symposium on Rendering.
    Jun 10, 2008 Glago's Guest premiered at Annecy; first production to use Ptex.
