//
// The scene created in this example is a textured cube, a pyramid
// with materials mapped on it's faces and triangle deformed by vertex cache.
// An animation stack displays 6 different angles of all models.
//
// The example illustrates how to:
//        1) create a cube in mesh
//        2) map textures on diffuse, ambient and emissive channel of the cube
//        3) create an UV set for each channel with a texture for the cube
//        4) create a pyramid in mesh
//        5) create and map materials on the diffuse channel for each faces of the pyramid
//        6) create a cube with our custom mesh type
//        7) create and map materials on the diffuse channel for our custom mesh cube
//        8) create and add to our custom meshed cube a User Data Layer
//        9) create vertex cache deformer (by default maya caches are created in 64bits (mcx extension))
//       10) create an animation stack
//       11) animate vertex
//       12) export a scene in a .FBX file
//
//
// 1. To test vertex (3 doubles) cache (default) :
//
// ./ExportScene03 cacheFileName
//
// 2. To test int32 cache :
//
// ./ExportScene03 cacheFileName 1
