The RTI Viewer allows you to load and examine images created with relectance transformation techniques. The tool supports these formats, collectively called RTI files: X Polynomial Texture Maps (PTM files) X Hemispherical Harmonics Maps (HSH files) X Universal Reflectance Transformation Imaging (URTI files) The viewer can display both single-view and multi-view images; a mulit-view RTI is a collection of single-view images together with optical flow data that generates intermediate views.
