Specifies the type of mesh optimization to be performed.
Syntax
typedef enum {
D3DXMESHOPT_COMPACT = 0x01000000,
D3DXMESHOPT_ATTRSORT = 0x02000000,
D3DXMESHOPT_VERTEXCACHE = 0x04000000,
D3DXMESHOPT_STRIPREORDER = 0x08000000,
D3DXMESHOPT_IGNOREVERTS = 0x10000000,
D3DXMESHOPT_DONOTSPLIT = 0x20000000,
D3DXMESHOPT_DEVICEINDEPENDENT = 0x40000000
} D3DXMESHOPT;
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_DONOTSPLIT
While attribute sorting, do not split vertices that are shared between attribute groups.
- D3DXMESHOPT_DEVICEINDEPENDENT
Affects the vertex cache size. Using this flag specifies a default vertex cache size that works well on legacy hardware.
Remarks
The D3DXMESHOPT_STRIPREORDER and D3DXMESHOPT_VERTEXCACHE optimization flags are mutually exclusive.
The D3DXMESHOPT_SHAREVB flag has been removed from this enumeration. Use D3DXMESH_VB_SHARE instead, in D3DXMESH.
