.file extension YDL - Powerflip YAODL 3D image file
File extension YDL description:
YAODL stands for 'Yet Another Object Description Language', and is a format for three-dimensional models that supports NURBS, polygons, and quad-meshes, and object properties such as facet or vertex normals, texture coordinates, and object, facet and vertex colors. It also supports hierarchical models, coordinate transformations (rotations, scales, translations), and instancing (using the same data more than once).
It is not an official data format of Silicon Graphics, it is just a data format created for the powerflip demo program.
