Many projection environments require images that are not simple perspective projections that are the norm for flat screen displays. Examples include geometry correction for cylindrical displays and some new methods of projecting into planetarium domes or upright domes intended for VR. The standard approach is to create the image in a format that contains all the required visual information and dis
Also known as the Stanford Triangle Format Source code examples: ply.h, plytest.c, plyfile.c, plydocs.txt Example of an ascii ply file Introduction This document presents the PLY polygon file format, a format for storing graphical objects that are described as a collection of polygons.

Note: Not all of these textures tile (at least not automatically). By clicking on any texture you will be given a page with the texture as a tiled background image where you can visually inspect the result of a straightforward tiling. Mirror tiling will need to be arranged by yourselves, ie: WWW browsers don't yet support it. Recent contributions have been made by Hasina Bee, John Young, James Car
