Project 2 – Lightning
So, I initially set out to make an awesome procedurally-generated 3D landscape. Eventually, I sat in front of this kinda dull, circa 2002 CG world and, thanks to another pair of eyes, realized it needed more to bring it to life. So, I decided to try to generate some lightning for the environment. In the end, the lightning turned out decent, but didn’t spruce up my environment enough to make it much better though it seemed to look good on nighttime landscape photos. Built with Processing.
The following papers helped provide some insight into visualizing lightning:
Visual Simulation of Lightning by Reed & Wyvill
Fast Animation of Lightning Using an Adaptive Mesh by Kim & Lin
Hi Rich – here are the comments from the class crit.

That is pretty cool, lightning seems a bit too jagged

Sound Effects Please!!
I actually really liked the 3D landscape you showed. Something about that low-poly old school 3d game look…
Noice.
Is the lightning actually seeking the high points in the photo?
very cool final form of your exploration
Nice explanation of process. The shading/halo really adds something. A shame it doesn’t look as good on the projector. Does it actually have some understanding of the shape of the skyline in your photo, or does the lightning just strike at some arbitrary y coordinate? Neat project. The discussion of perceived simulation versus real simulation this has sparked is also very cool. -SB
Another cool effect would be to create a flashing glow in the clounds to create the illusion of internal/far away lightning
Look at Robert Hodgin’s meteorties: http://www.barbariangroup.com/posts/1842-augmenting_a_webcam
Nice process. how about a hand cursor, pointing upside down? 🙂
Have the lighting relate to the space — falling between layers, hitting pointy things.

Wow!
