ID3DXPatchMesh::Tessellate method
Performs uniform tessellation based on the tessellation level.
Syntax
HRESULT Tessellate(
[in] FLOAT fTessLevel,
[in] LPD3DXMESH pMesh
);
Parameters
-
fTessLevel [in]
-
Type: FLOAT
Tessellation level. This is the number of vertices introduced between existing vertices. The range of this float parameter is 0 < fTessLevel <= 32.
-
pMesh [in]
-
Type: LPD3DXMESH
Resulting tessellated mesh. See ID3DXMesh.
Return value
Type: HRESULT
If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be one of the following: D3DERR_INVALIDCALL, E_OUTOFMEMORY.
Remarks
