ID3DXMATRIXStack::RotateYawPitchRoll method (D3dx9math.h)
Rotates (relative to world coordinate space) around an arbitrary axis.
HRESULT RotateYawPitchRoll( [in] FLOAT Yaw, [in] FLOAT Pitch, [in] FLOAT Roll );
The yaw around the y-axis in radians.
The pitch around the x-axis in radians.
The roll around the z-axis in radians.
If the method succeeds, the return value is D3D_OK.
This method adds the rotation to the matrix stack with the computed rotation matrix similar to the following:
D3DXMATRIX tmp; D3DXMatrixRotationYawPitchRoll( &tmp, yaw, pitch, roll ); m_stack[m_currentPos] = m_stack[m_currentPos] * tmp;
Because the rotation is right-multiplied to the matrix stack, the rotation is relative to world coordinate space.
