Hi all, I''m trying to create some lensflares. I want to find the place my light is at. I could use gluProject, but i don''t have a (x,y,z) location, because my light is directional. How do I find out where my light is on screen? thanx, Marty

Directional lights have no position by definition. You can create a fake light position using something like:

fake_light_pos = player_pos - light_direction * some_huge_value; 

Then use this fake position with gluProject or do screen projection yourself.


You should never let your fears become the boundaries of your dreams.
