Hello guys!! 
I’m searching for some material that show the implementation using the OpenGL selection, all the documentation that I have is informing that this mode is too slow. Is it true ? If yes, does anyone know another way to make it ?
PS.: If anyone can send me some source code, I’m developing my application using the Win32 SDK. Just to inform you, I want to make something that will allow the user to selection some control points and then move it, does anyone have some source code to show this ?
Best regards
Kurt
