...probably nobody, but looks cool laugh

I experimented around with the basic idea of the Light pre-pass [ENGEL] and got this awesome rendering technique
wich allows you to render a huge amount of dynamic lightsource depending on the light-ranges and the viewers position.

The following scene was rendert with 60fps on my GTX285 (30-40fps on Slins 8800GS)
and contains 700 low-range light sources. Every particle is a lightsource:





Thanks to ChrisB who gave me an essential hint wink

I uploaded two demos here. One with 700 lights and the other with 350.
Let me know how fast it runs on your hardware (fps are limited to 50, use the console to change this).

I do not take any responsibility for hardware damage caused by running this demo.

PS: Before people start asking: to make use of this stuff you have to adapt your whole rendering pipeline
so I couldnīt easily contribute this without building a complete rendering system.
But you can always hire me for payed jobs wink

Wow, this is amazing!
2006 Notebook, XPS M1710, Dual Core 2.0, 512MB 7900 GTX:
350 lights: 20fps but it feels and looks like ~40fps, how come?
700 lights: 13fps.

If I take the startposition of the camera
350: 30fps
700: 20fps

If I scroll out to have all lights rendered to the screen at once, the fps are much higher Oo
