D3DXMatrixMultiplyTranspose

Determines the product of two matrices, followed by a transpose.

D3DXMATRIX* D3DXMatrixMultiplyTranspose(
  D3DXMATRIX* pOut,
  CONST D3DXMATRIX* pM1,
  CONST D3DXMATRIX* pM2
); 

Parameters

pOut

[in, out] Pointer to the D3DXMATRIX structure that is the result of the operation.

pM1

[in] Pointer to a source D3DXMATRIX structure.

pM2

[in] Pointer to a source D3DXMATRIX structure.

Return Values

Pointer to a D3DXMATRIX structure that is the product of two matrices.

Remarks

The result represents the transformation M2, followed by the transformation M1, tranposed by T (Out = T(M1 * M2)).

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixMultiplyTranspose function can be used as a parameter for another function.

This function is useful to set matrices as constants for vertex and pixel shaders.

Requirements

Header: Declared in D3dx8math.h.
Import Library: Use D3dx8.lib.
