What’s the best way to work with a large 3D scene?
Hi there
Basically ive got a shot of a close up of a water bottle, this then zooms out pretty far to reveal it is in a vending machine and then zooms out further to reveal a whole room. im working in HD, and so it means each bottles has to be around 3000 pixels high to have the quality good enough on the close up, but when i zoom out it’s taking a crazy long time.
Can anyone recommend anyways of helping with something like this?Cheers

I think you would be best served by breaking up the project in Max into the tight shot, the medium shot, then the wide shot. This will give you the option to adjust the resolution of your models to look best in the scene without wasting bandwidth on models which don’t need high resolution. Then you can stitch the 3 scenes together in After Effects, or whatever compositing software you’re using, and have even more options to do blurred zooms, camera moves, etc.. Good luck with it.

I assumed when you said 3D that you were working in a 3D package, such as Max. That may not be the case, but at any rate, I would still break up the project into the 3 scenes, and scale your resolution to the minimum rez at which it looks really good.Joe

Hey Joe
Yeah im doing it all in After Effects. So, what would you recommend is the best thing to do? Have a composition for each close, mid, and wide shot? but then so when you are zooming out of the close shot, do you switch to the mid shot and continue zooming out? but how do u get the speed of the zoom the same in each composition?
thanks for your help!

There was once a great tutorial called “Falling from Heaven” at AEFreemart that used google earth images to simulate falling from the sky to the ground but everything was always in perfect focus and you had full control over th speed in which you zoomed to street level. I went to AEFreeMart but it was down at the moment. If you can find it I think it will be a great help.
Good luck

You could just lay the low-res shot over the high-res shot (same X-Y position), then set its mode to Difference, then move it in Z-space until it turns all black, and therefore matches the apparent size of the high-res shot.
Difference mode is a good trick for matching one thing over another identical thing.

Check out Andrew Kramers Earth Zoom tutorial, it has some easy tips for using multiple images at large resolution that may be applied to your project. By using scale and masks you could easily stitch the different res images.
