Polynomial Texture Maps (PTMs) are a simple representation for images of functions instead of just images of color values. PTMs can be used as light-dependent texture maps for 3D rendering, but typically are just viewed as ‘adjustable images’.[1][2][3]
[edit] File Information
PTM files are binary files with the ASCII header PTM_1.2
PTM_FORMAT[4]
[edit] Software & Samples
- Relight - a library to create and view (on the web) relightable images (RTI)
- RTIBuilder
- Sample PTM Images
