Model with 2694 faces rendered with Ptex. No explicit UV assignment was used. The largest texture layer, the fine-scale displacements, has 836 million texels stored in a single Ptex file with individual face resolutions ranging from 64 x 64 to 2048 x 2048 texels. No seams are visible across faces, even under close magnification.

Motivation

There were many drawbacks to traditional texture mapping methods that led to the development of Ptex: Ptex addresses all these issues by eliminating UV assignment, providing seamless filtering, and allowing any number of textures to be stored in a single file.

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.
