About:
Ptex is a high-performance texture mapping system that eliminates the need for complex UV mapping by applying textures directly to mesh faces. It provides a seamless, per-face texture mapping solution that scales efficiently for complex geometry. This system is widely used in feature film production for its ability to handle massive datasets with consistent memory usage.
Key Features:
  • Per-face texture mapping without UV coordinates
  • Efficient memory usage with texture caching
  • Support for both face-varying and face-varying textures
  • Robust filtering and interpolation algorithms
  • File format for storing Ptex data
Use Cases:
  • Feature film production for complex character and environment texturing
  • Scientific visualization requiring precise texture mapping on arbitrary meshes
  • CAD/CAM applications needing accurate material assignment
Alternatives:
  • UV mapping – Traditional UV mapping requires manual unwrapping and can introduce seams, while Ptex is automatic and seamless
  • Mari – Mari is a painting application that supports Ptex, but Ptex itself is the underlying texture mapping technology
