D3DXComputeBoundingBox

Computes a coordinate-axis oriented bounding box.

HRESULT D3DXComputeBoundingBox(
  CONST D3DXVECTOR3 * pFirstPosition,
  DWORD NumVertices,
  DWORD dwStride,
  D3DXVECTOR3 * pMin,
  D3DXVECTOR3 * pMax
);

Parameters

pFirstPosition

[in] Pointer to the first position.

NumVertices

[in] Number of vertices.

dwStride

[in] Count or number of bytes between vertices.

pMin

[out] Pointer to a D3DXVECTOR3 structure, describing the returned lower-left corner of the bounding box. See Remarks.

pMax

[out] Pointer to a D3DXVECTOR3 structure, describing the returned upper-right corner of the bounding box. See Remarks.

Return Values

If the function succeeds, the return value is D3D_OK. If the function fails, the return value can be one of the following: D3DERR_INVALIDCALL.
