Activity Forums Adobe After Effects A decent 3D floor

  • A decent 3D floor

    Posted by Rob Wolf on June 16, 2007 at 8:05 am

    I’m beginning to venture into the mysterious 3rd dimension in After Effects and have been running into a problem doing something that seems like it should be easy:

    How do I get a decent looking 3D floor?

    I’ve played around with solids, and they work, but often have an abrupt edge, to matter how big I make it. I’ve tried playing around with depth of field, but that doesn’t seem to do enough to blur the background as it heads off into the horizon.

    I’ve also tried faking it with some 2D gradients, but those aren’t all that convincing, nor do they keep up once I start moving the camera.

    Any suggestions?

    Thanks,
    Rob

    You mean an infinite ground plane?

    It’s not something AE does naturally. You could consider applying Motion Tile to the floor, but if the layer gets too big, you could crash. The only option I’ve found (so far) is Aurora Sky, which may allow you to tile an image infinitely. I’ve never used the plug, so you’re on your own. 🙂

    But I’d also consider rejigging the comp so an infinite ground plane isn’t necessary.

    You can do it but it isn’t easy. I made a desert floor for a 3 minute 5-screen project for a museum. The screens represented the view from inside a 1920 railroad car (thus the sepia tone). The floor was constructed from a 16,000 pixel panorama. I cut the panorama into 130 layers–each one placed further back in 2D space with the loop speed adjusted and then soft masked to hide the seam. The most foreground loop plays in 8-seconds and each subsequent layer moves slower until finally the furthest layer barely moves at all.

    I’ve uploaded an example at https://virlt.com/floor.mov

    At this resolution (25%) you can’t really notice the detail in the furthest layers but they definitely show up in the final render–which, btw, took 8-computers 44 hours to render on AE7.

    Sorry, but I noticed that the link won’t work from within this forum. Can someone explain to me why that’s the case? In the meantime, you can just copy the link to a new browser window and it should work.

    You have not set the permissions on the FTP’d file to allow the “public” to read it.

    That is why your audience is getting the “forbidden” notice.

    Best,

    Hi Ron, I don’t want to turn this thread into a discussion of links and ftp, but briefly, the file’s permission are correct and in 10 years, all clients have been able to access my site. Not sure what’s up but I do notice that you can paste the link manually in another window and it works.

    I suspect that your permissions do not allow your files to be “3rd partied” in their display — meaning that because they are being viewed inside our wrapper (instead of directly as when you open a new window and view the link there) they will not display.

    This disallows sites from sucking your files into them and highjacking your content. Unfortunately, it also disallows you from making a direct post to it such as here at the COW.

    That is what I suspect.

    Just to be nitpicky, that’s not so much a floor as a series of walls 😉

    But in answer to the original question, you will probably need to use some sort of ‘wall’ to fake the horizon. If you look out at the real world, for example, there is rarely… no, I’m going to say it… never an infinite plane =)

    I never promised a rose garden. There’s no question that this IS a series of walls. Every other approach I utilized just plain wouldn’t work in AE’s 3D space. I tried to use HD footage but since the “train” had to come to a slow stop at the station, there was no way to time remap without severe stuttering.

    Hey Jim….I just added a www at the front of the link and it worked fine.

    Always a way…
