Transforms an array (x, y, z, 1) by a given matrix, and projects the result back into w = 1.
D3DXVECTOR3 *WINAPI D3DXVec3TransformCoordArray( D3DXVECTOR3* pOut,
UINT OutStride,
CONST D3DXVECTOR3* pV,
UINT VStride,
CONST D3DXMATRIX* pM,
UINT n
);
pOut: [in, out] Pointer to the D3DXVECTOR3 structure that is the result of the operation.
OutStride: [in] Stride between vectors in the output data stream.
pV: [in] Pointer to the source D3DXVECTOR3 array.
VStride: [in] Stride between vectors in the input data stream.
pM: [in] Pointer to the source D3DXMATRIX structure.
n: [in] Number of elements in the array.
stride翻译成中文是什么意思?
谁给解释下OutStride和VStride是什么意思?
这个函数和D3DXVec3TransformCoord有什么区别? |
