PTex released as open source
|
 Ptex became an open source project. Ptex is a texture mapping system developed by Walt Disney Animation Studios for production-quality rendering.
Ptex was used on virtually every surface in the feature film Bolt, and is now the primary texture mapping method for all productions at Walt Disney Animation Studios.
Ptex features:
- 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.
- Supports Catmull-Clark subdivision surfaces (including quad and non-quad faces), Loop subdivision surfaces, and polymeshes (either all-quad or all-triangle).
- Several data types are supported including 8 or 16-bit integer, float, and half-precision float.
- An arbitrary number of channels can be stored in a Ptex file.
- Arbitrary meta data can be stored in the Ptex file and accessed through the memory-managed cache.
