Hello,
Now that hardware has got fast enough to light a terrain in real time,
I'm giving it a go.
How do I configure an OpenGL light to be directional, but without any
position? For example, suppose I wanted to simulate a distant sun. I
don't want attenuation with distance and light 'beams' are all parallel
to each other?
GL_SPOT_DIRECTION seems to do something else.
Thanks
