For real-time uses, these are often simulated as a sphere for "point" lights or a disc for directional lights. There are also techniques that can utilize constrained planes; the 3D equivalent of what you're looking for, I think. Unfortunately, I know very little about these other than their existence so I can't really provide a decent answer to your question. | |

| Dec 22, 2015 at 17:20 | comment | added | flotothemoon | @Draco18s Alright, thanks for the reply. I find it kind of hard to believe that there are no lights like this at all - not every single light in every 2D game every can be punctual right? That link is great, looks like the fellow uses a similar approach to the one I proposed; intersecting with a light "line", as far as I understand that is. | |
| Dec 22, 2015 at 16:51 | comment | added | Draco18s no longer trusts SE | The last time I saw lights that worked like this, it was in a 3D modeling stuidio (3D Max?). I've never seen them anywhere else. A little searching shows that OpenGL does not have them, but this fellow managed an approximation. Maybe that will help you. Post is old enough that the demo images are missing, however. | |
