simulating projection onto walls in flat panoramic map
How’s it goin guys? Alright, so I’m doin’ a music video and the basic visual thing going on is a 180 degree pan of a backyard. The camera is following a projection moving along the walls back and forth. So what I’ve done is take a 360 degree panoramic with a 7 megapixel camera and after stitching it, turned it into a 3d environment using trapcode Horizon. I’ve done test renders of the camera movements and it looks great. Here’s the problem: How do I take the footage of the singer and have it deform in perspective as if it were being projected onto the walls in this flat pano map? Already tried using Pshop vanishing point but since the perspective is kinda wonky (which I like) all I get is junk when I export to After Effects. Any advice would be greatly appreciated.
Thanks guys
Gilbert

As far as I under stand it, any 3D layer in AEFX will move with the Horizon plugin. To put it another way, the Horizon panorama is “Camera Aware”, so anywhere you point the AE Camera the Horzon background will respond.
So just put a video clip in your comp, click the 3D Layer button so you can move it around in 3D, then to a key/garbage mask to see if moving the camera will work they way you want.
VPE from photoshop will give you and additional camera which won’t work. But it will give you textured planes which you could place in your “scene”.
Also don’t try and do anything with video in Photoshop…please. Just stay here in AE where it’s safe.

Wow, that was quick man! I’ll give it a shot.

okay so I dropped the clip into the comp and made it a 3d layer.
Now when I move the camera it floats around like a hologram. Doesn’t look like it’s being projected onto the wall.
Previously I had corner pinned the clip to fake the perspective and then animated it sliding (keyframing the pins) over the corner.
I duplicated the clip, and changed the pins to correspond with the adjecent corner.
The problem was that the two images (masked off to look like halves of one whole) were out of sync or stretched too much or, I dunno. Picture a clip of a circle being projected onto a wall and at the corner the image splits and the ball looks like a double image.
Is there some plugin that I can use to animate the distortion so that it looks as though its crawling long the wall in perspective, or rather pinned to faux perspective?
Here’s a picture of what the distortion should look like (to be animated sliding left of course).

Please let us know how that works out, and if you could provide a link to the finished video that would be awesome. Thanks.
