The D3DXMatrixPerspective function builds a right-handed perspective projection matrix
D3DXMATRIX* D3DXMatrixPerspective( D3DXMATRIX* pOut, float w, float h, float zn, float zf );
A pointer to a D3DXMATRIX structure that is a right-handed perspective projection matrix.
All of the parameters of the D3DXMatrixPerspective function are distances in camera-space. The parameters describe the dimensions of the view-volume.
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixPerspective function can be used as a parameter for another function.
The default projection matrix setup by the D3DXCreateContext and D3DXCreateContextEx functions is a left-handed perspective projection with a field-of-view (fov) of pi/2 radians.
