Vertual Movie Theater
Ok i would like to create a vertual movie theater. Now i can create the 3d space and everything but would like this effect.
You know when you are in a smokey theater, you can see the image coming from the projector to the screen? In streams of light that match the image playing of course.
Does anyone out there have a concept of how to recreate this in AFTER EFFECTS CS3 or am i barking up the wrong software?

PS. Aharon i am counting you for this one Broa!

Just in case Aharon’s busy changing diapers, you’ll want to look at Trapcode’s Shine plugin. If you don’t have that then try CC Light Burst.

I was able to somewhat sloppily create this effect (assuming a 640×480 image):
1. Create a comp @ 10×480 with the projected movie inside.
2. Rotated the comp 90°Y in 3D space and used Corner Pin to distort the image into the triangular shape of a projector beam.
3. Duplicated the process across the entire image.
4. Changed transparency mode of “light beam” comps to add and adjusted transparency.My result using only 3 light comps (left edge, right edge, center) should be attached. If this looks like what you’re looking for, let me know and I can see if I can get you a better description.
Also, keep in mind that this is just approximating volumetric light. There will be glitches, namely that using 10 pixel wide chunks like this will leave 10 pixel wide gaps along the screen in 3D space. But now I think I’m just not making sense any more.

Very cool! I’m curious with Step 1 on the size of the comp and what does Step 3 actually entail?
Perhaps an AEP will be good for us?

The reason for the size of the comp was to grab just a small slice of the image and turn it on its side & stretch it so it looks like streaks of light/dark going from the projector to the screen.
Step 3 would entail making one comp for each section we want to stretch. In my example, there’s three. One for the left edge, one for the center, and one for the right edge. If we wanted to cover an entire 640×480 image, you would need 64 comps, one for each of the 10 pixel sections of the screen.I’ve attached the project file & assets (AE CS3) for anyone to take a look at.

Take a look above. I just posted an AE project file, which would probably help more than my rambling ever would.

that is it! i just did not completely follow your instrux. Can you assist any more?
thanks so much!

Yar, nice work, Paul, thanks for your contribution.
Historicla note: when AE added 3d and light transmission, Brian Maffitt created a projection system using three copies of a color movie clip, each reduced to a single color channelgrayscale image. He positioned three spotlights in a triangle and shined them through the individual movies using them as gobos. Each of the three lights was red, green, or blue. He had a layer he called SCREEN and all three lights landed on the screen. The resulting projected image was curiously super-realistic. Someone added CC Light Burst or Radial Glow to give the projectors some volumetric lighting and we all got a chance to animate the camera moving around the scene. Card Dance was used to create an appreciative audience in the movie theater.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

David-
You don’t happen to have the link to that thread around, would you? I’d be curious to see it.

This oldie is the coolest 3D movie projector with AE I can remember. Click on Filip’s embedded movie about halfway down:

Here is another thread by Filip explaining more, but to my eye the still pics don’t do the final product justice (as the above movie does):
