ID3DXSPMesh::ReduceVertices Method

Reduces the number of vertices in a simplification mesh.

Syntax

HRESULT ReduceVertices(      

    DWORD Vertices
);

Parameters

Vertices

[in] Number of vertices to which to reduce the primitive count.

Return Value

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be D3DERR_INVALIDCALL.

Remarks

This method performs edge collapses to reduce the number of primitives to the value specified in Vertices. It is not always possible to reduce a mesh to the requested value due to certain restrictions.
