Seems like font rendered on DX window using D3DXFont, the coordinates are passed as Window Coordinates... So i am just wondering how to specify and 3D Coordinate in the scene and then get D3DXFont to render on that 3D Point. Is there any easy way to handle this.. or do i have to do it manually by multiplying the 3D point with WorldView and Projection matrics and then doing the scaling and etc. Also i need to handle Viewports.
