The Bin Mesh plugin holds an optimized representation of the model topology. Triangles are grouped together into Meshes by their Material and stored as triangle strips when the rpGEOMETRYTRISTRIP flag (0x1) is set in the Geometry, otherwise as triangle lists. In pre-instanced files, the chunk looks different according to platform.
Structure
uint32 flags (0 = tri list, 1 = tri strip)
uint32 number of Meshes (numMeshes)
uint32 total number of indices
#repeat for numMeshes
uint32 number of indices (numIndices)
uint32 material index (into the Geometry's material list)
#if pre-instanced
#if platform == OpenGL
uint16 indices[numIndices]
#endif
#else
uint32 indices[numIndices]
#endif
#endrepeat
To decide if the file is an OpenGL file when reading, check the platform of the Native Data chunk. When no vertex indices are stored here, the pre-instanced geometry uses no indices or they are stored in the Native Data.
