Question 2D render Images with "red-green"-3d-information???

Hi!

Is there any way to produce with Maya or Photoshop 2D-Images with red-green depth information to view these pictures in 3D with these red-green(sometimes also red-blue) glasses? I hope you know what I am talking about and you can help me ..

Best Regards

Markuz

These images are called anaglyphs

Yes the can be done in Maya, although they have to be composited.

If you want to try you hands at it, might want to to do this.

Create your object, and then create two cameras separated by about 5 or 7 cms (the distance from the eye´s pupils really) and render both passes. Then in Photoshop fiddle with the colors to composite the image. You might want to play a bit with the settings to get better results.

You also might want to render another pass just between these two cameras (which would be the gray one you see in lot´s of these images)

Here are some resources that might help you:
Creating Stereograms
Anaglyphic 3D Images
Anaglyph Printing

Hope it helps!

YOU ARE A GOD! ..

One thing: How do I know when these two careas are 7 cm away from each other? Perhaps I'll find something at your links, but they'll surely be not extra for maya.

Thank you very much!

Regards

Ah, I think the less I seperate both cameras, the more far away the object appears, right?

You´re welcome! always glad to help a bit!

Well, you could try to guesstimate it a bit by going into preferences and changing your units to cms. Then each division in the grid would be 1 cm, count them and then grid snap the cameras.

The other way would be using a special node in Maya (distanceBetween) but I certainly don´t feel like I´m the best guy around here to talk about that node.

Hope it helps ...

I think you are right ... since that would be governed by basic ray perspective laws.

It shouldn't matter how far they are away, since my abstract object can be small or big

..indeed, yes ...

BTW: I took two cameras, seperated them a bit, but made them look at ONE single point. That is right, isn't it? They do not look parallel, doesn't they?

I suppose so since the eyes always have to fix around a point. That´s how the brain recolects 3d information.
