// Contains data purposely formatted for a dma copy into a D3D Vertex Buffer. |
|
// The file is divided into two partitions, the foremost contains the static |
|
// portion (header), the latter contains the streamable compliant portion. |
|
// The streamable component starts and ends on a sector (512) aligned boundary. |
|
// The header identifies the vertex format of the data and the atomic sizes of each component. |
|
// The hierarchial mesh is flattened for dma but the vertex counts are available |
|
// per mesh to transfer each mesh individually. |
