// AC3D loader for models generated by the AC3D modeller (www.ac3d.org)
// part of this source code were supplied by the AC3D project (Andy Colebourne)
// eg the basic parsing of an AC3D file, values of constants in this include file..
// Conversion from AC3D scenegraph to OSG by GW Michel.
//  == Opinion: ac3d is a valuable, very easy to use 3D modeller.
//   use can be picked up in hours rather than weeks.
//  Other loaders and modellers are available for OSG.
