D3DXComputeBoundingSphere

Computes a bounding sphere.

HRESULT D3DXComputeBoundingSphere(
  PVOID pvPointsFVF,
  DWORD NumVertices,
  DWORD FVF,
  D3DXVECTOR3* pCenter,
  FLOAT* pRadius
);

Parameters

pvPointsFVF

[in] Pointer to a buffer containing the vertex data around which to calculate the bounding sphere.

NumVertices

[in] Number of vertices.

FVF

[in] Combination of Flexible Vertex Format Flags that describes the vertex format.

pCenter

[out] D3DXVECTOR3 structure, defining the coordinate center of the returned bounding sphere.

pRadius

[out] Radius of the returned bounding sphere.

Return Values

If the function succeeds, the return value is D3D_OK.

If the function fails, the return value can be one D3DERR_INVALIDCALL.
