D3DXVEC3TRANSFORMNORMAL function
Use matrix transform 3-D vector standard form.
definition:
D3DXVECTOR3 * WINAPI D3DXVEC3TRANSFORMNORMAL (D3DXVector3 * Pout,
Const D3DxVector3 * PV,
Const D3DXMatrix * PM
);
Parameters
pout
[IN, OUT] points to the results of the D3DXVECTOR3 results.
PV
[in] Pointing vector of D3DXVector3 structure.
pm
[in] points to the matrix of the D3DXMatrix structure.
return value:
Refers to the conversion of the D3DXVector3 structure.
Description:
This function is converted with a matrix PM transform vector PV standard form (x, y, z, 0), not a homogeneous coordinate form.
If a non-affine matrix transform, then this matrix should be reverse after the operation is transferred to this function.
The function return value is the same as the POUT parameter. This allows the function D3DXVEC3TRANSFORMNORMAL to use parameters of other functions.
