D3DXMESHOPT

Specifies the type of mesh optimization to be performed.

enum _D3DXMESHOPT {
    D3DXMESHOPT_COMPACT       = 0x01000000,
    D3DXMESHOPT_ATTRSORT      = 0x02000000,

};

Constants

D3DXMESHOPT_COMPACT

Reorders faces to remove unused vertices and faces.

D3DXMESHOPT_ATTRSORT

Reorders faces to optimize for fewer attribute bundle state changes and enhanced ID3DXBaseMesh::DrawSubset performance.

D3DXMESHOPT_VERTEXCACHE

Reorders faces to increase the cache hit rate of vertex caches.

D3DXMESHOPT_STRIPREORDER

Reorders faces to maximize length of adjacent triangles.

D3DXMESHOPT_IGNOREVERTS

Optimize the faces only; do not optimize the vertices.

D3DXMESHOPT_SHAREVB

Share vertex buffers.

Notes

The D3DXMESHOPT_STRIPREORDER and D3DXMESHOPT_VERTEXCACHE optimization flags are mutually exclusive.
