I there,

When im rendering me scene, i want to add flars on the point where a light is. The flare needs to be visible only when the light point is visible.
I could do a collision check on the geometry beteen the camera point and the light point, but i think it will be slow with a complex scene and a lot of lights...

Mayby I could get a point in the backbuffer end with that information draw the flare ??
