So I was experimenting a bit with the look of the lasers and I realized they look a lot better if one fuzz the edges a bit. Have a look for comparison (click for larger):

Old style lasers (fuzziness = 0)

Lasers with fuzziness = 0.5

Lasers with fuzziness = 0.75

Lasers with fuzziness = 1

Take especial note to the intersections of lasers and the softness of the rainbow.

In my opinion, the fuzzy lasers look a lot better than the old style – but opinion was split at the office, and so now I’m asking for yours. Which do you prefer? And what level of fuzziness? Should old scenes be automatically updated with the new look? Or should this be a per-scene setting, so that old scenes keep the old look and new scenes get the fuzzy look (by default)?

(PS: Fuzziness only changes the look of the laser – nothing more, nothing less. Also, fuzziness will only be available with shaders/anti-aliasing turned on)

Edit: scratch that – fuzzy lasers will work, and look almost as good, even without shaders!
