D3DXComputeBoundingBox Function

Computes a coordinate-axis oriented bounding box.

Syntax

HRESULT D3DXComputeBoundingBox(      

    LPD3DXVECTOR3 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 Value

If the function succeeds, the return value is D3D_OK.

If the function fails, the return value can be

D3DERR_INVALIDCALL

The method call is invalid. For example, a method's parameter may have an invalid value.
