Project

Projects a 3D vector or array of vectors to the screen.

Syntax

IppStatus ippmProject_m4v3_32f (const Ipp32f* pWorld, const Ipp32f* pView, const Ipp32f* pProj, const Ipp32f* pSrc, Ipp32f vpWidth, Ipp32f vpHeight, Ipp32f vpZnear, Ipp32f vpZfar, Ipp32f* pDst);

IppStatus ippmProject_m4v3a_32f (const Ipp32f* pWorld, const Ipp32f* pView, const Ipp32f* pProj, const Ipp32f* pSrc, int srcStride0, Ipp32f vpWidth, Ipp32f vpHeight, Ipp32f vpZnear, Ipp32f vpZfar, Ipp32f* pDst, int dstStride0, int count);

Parameters

pWorld: Pointer to the world matrix.
pView: Pointer to the viewport matrix.
pProj: Pointer to the projection matrix.
pSrc: Pointer to the source vector or array of vectors.
srcStride0: Stride between the vectors in the source array.
vpWidth: Width of the viewport.
vpHeight: Height of the viewport.
vpZnear: Minimum depth of the viewport.
vpZfar: Maximum depth of the viewport.
pDst: Pointer to the destination vector or array of vectors.
dstStride0: Stride between the vectors in the destination array.
count: The number of vectors in the arrays.
