Stereoscopic 3D - Is it possible? If so how?

#1

Greetings,

I am using Combustion 3 and possibly upgrading to 4.

Is there a way that I can render out images in stereoscopic 3D?

Perhaps pulling layers our in the Z axis and applying a plugin? Is there a plugin out there for this? Where can I find it and how can I use it?

What type of 3D glasses would be required for this?

Please help,

Thank you,

Chris

I’ve done a few stereo shows. It’s really simple. Just put 2 3d cameras both pointing to the same poing in space. Then cut out objects from your 2d shot and put them at different depths.

To make the red and blue anaglyph, grab the luminance from the left eye and put it in the red channel and grab the green and blue from the right eye.

deke,

What does the render look like? Is there a split screen? Is there two separate renderfiles that have to come togethor somehow?

Please let me know what to do after I do your previous instructions.

Thanks!

The way I gave above results in a red/blue anaglyph (cheap red blue glasses). That results in 1 image. If your delivering for something that uses polarized glasses or shutter glasses, just output separate L&R eye images. The output device should mix the two, but it depends the output device. Find out the requirements for that first. Some systems will vary on what they require.

Thanks beaker,

It wont be the red/blue glasses type, it will be the polarized or shutter glasses type.

  1. Just wondering, how far apart do I put the two cameras from eachother? Does it matter?

  2. Just out of curiousity, if I wanted to go for the 1 cheap red blue image, how are the two images mixed togethor to make the one? Is it just an opacity thing over eachother?

Yea it does matter otherwise your eyes might bug out. If the 3d scene is to scale, then you want them about as far apart as your real eyes are, which is about 2.5".

Here are a few links that will help:

The place where the two targets of the cameras meet is where everything is going to be flat and then everything placed in front and back of those points in Z are going to be in 3d.

No, it is made like I mentioned in my first post:

awesome! thanks a lot!

Hi Beaker,

Thanks for all the help, I still have a couple (possibly stupid) questions.

  1. In combustion 4, I can’t seem to get 2 camera’s into the my workspace at once without creating a new composite. Is it possible? Or should I render out sequence 1 first, move the camera and render out sequence 2 next?

  2. Also in combustion4, how can I set it up so that it is an accurate 2.5" of space between each camera position and make sure that the are pointed at the same focal point? - I am usually a 3D animation user, the cameras in this software dont seem to have an “interest” that can be controlled.

Thanks again,

Chris
