Explosions and VR simulation
I know this goes beyond an AE scope, but I thought I’d look for suggestions…
I’ve been asked by a client to come up with a small, enclosed booth (max. 8′ x 10′) for a trade show that has an explosion simulator in it. It’s trying to simulate an industrial electrical explosion along with heat, light, explosion sounds, and shockwaves. I figured I do the compositing in AE, along with clips from Artbeats etc…, but the heat and shockwaves have got me a bit stumped – along with setting up a trigger for them to go along with my footage…
Any ideas?
THANKS!

FOr heat, you can create a solid layer and use the fractal noise effect, animated. Precomp it (this won’t work otherwise) and using that precomped fractal animation as a displacement map for you BG footage. This creates a heat shimmer effect.
Not sure what to tell you about a shock wave. It depends on what you mean by that. Usually it;s a sphere that eminates out from the center of the explosion, and not that rediculous death star explosion ring that everyone is using since Lucas re-released Star Wars…
Personally, for all of my explosion needs i use the program called particleIllusion. It pays for itself the first time you use it professionally and has a really low learning curve. We have a forum here for pIllusion, where you can find out more:

The company website is https://www.wondertouch.com/
It is supposed to be out as a plugin for AE soon, BTW.

Thanks Aharon. I have and use Particle Illusion 3.0 – should have mentioned it in my post!
When I was talking about heat and pressure, I meant literally making users feel heat and pressure to go along with the video simulation. Since this will be at a trade show, I can’t get too far fetched, otherwise the show’s management will have safety concerns.

Do you mean physical heat and pressure?
A blast of warm air, along with some deep tones on a sub-woofer should do it.

Yes, that’s what I mean. It’s the timing issue that’s eluding me… I figure I can get some sort of rapid heat generator, but how do I time it to the video and sound. A pressure generator would be nice too, but that REALLY eludes me – even Google is having trouble with that one!

Sounds like you could do with a program to trigger a hair dryer, or perhaps, a fan heater. Or perhaps just a shunt to switch said fan heater to blow into the booth.
I’d go to your local university and suggest it to the electronics department as a project. The Electronics students in my dorm were always building this sort of thing.
As for synching it up to video, you’d probably be best looking at flash video. Make the movie in After effects, export it into Flash and use actions to trigger this other program (that the electronics students would have put together). It’ll still take some guess work for the timing, but all should be possible.
Alternatively, you could pay a kid to stand there all day and switch on the heater on cue 🙂
Actually, just found this: https://www.pontech.com/products/sv200/
It’s a PC controlled servo. So you could have your fan heater running, have Flash activate the program, which throws the switch, which redirects the air flow into the booth and then switches the air back.
