Blender 3D 2.50 and stereoscopic render in interactive applications

A lot of companies developing 3d applications like games and interactive displays are using stereoscopic render to allow users a better experience, by viewing all environments with a greater sense of depth. A few weeks ago I have already talked about stereoscopic render for architectural visualization, using even a pool to ask if you consider this type of technology for your visualization projects. The results of the poll show that artists are considering this technology as an interesting item for architectural visualization projects. Almost 40% of all answers point that we will have to learn how to use this feature.

I’m in the process of learning Blender 2.50 and preparing a lot of material that I have to migrate from 2.49 to 2.50 and this involves a lot of research and investigation. This week I found something quite useful for artists willing to use stereoscopic render in interactive applications. At the game engine we will be able to use several types of stereo render without the need for plugins or scripts.

Here is how it works!

Before we can see any of the stereo rendering options we must change the render output of Blender to be Blender Game.

When the Blender Game is set, the render menu will change and the will be a Stereo menu available. Press the Stereo button and pick one type of stereo rendering from the list.

If we press the P button to start a real time render with the Game Engine, we will see a stereo render in action.

Of course, by this hour it will be necessary to put your 3d glasses to see the differences on the visualization. I just found the feature and didn’t have the time to make serious tests with it, but it’s a great feature to have this already integrated to the game engine in Blender. I knew that I should keep 3d glasses in nearby to make tests with that kind of feature.

For stereoscopic render in animation and still images, you can try this script developed by Sebastian Schneider. It creates a stereo camera for Blender 3d.

    This is a great addition to the game engine. Do you know who developped it ?

    And I’m convinced it could be very nice for real-time architectural walkthrough.

    Is this any different than the stereoscopic options (under game-framing options in the render panel) in 2.49? Also, do the 3d glasses really work (I have always been curious, but don’t have 3d glasses to try it for myself).

    Thanks,
    Alex

    Hi Alex,

    Well, it`s only placed in a different menu. :)

    And yes, it works. I have a pair of 3d glasses here and it works just fine.

    Regards

    That’s what I though :-)
    I guess, then, I should get a pair. Seems like a cool technique.

    I think it doesnt work very well, but i think they’ll improve it once they add the focal lengh and eye separation menus, coz my scenes doesnt look very 3d to me with this…
    if you can send a scene that works for you so i can test it too t would be awesome!

    Hi,

    I’m making myself 3d glasses. I’m looking for the right lens colors, because someone says red-green and others red-cyan.

    What’s the right combination?

    Thx!

    Your output has no actual perspective, it’s just two of the exact same image, slightly offset.
    I’m still searching for a way to control the separation (how far apart the eyes are) and convergence (where the eyes meet), but if there is a setting it’s well hidden, which is odd considering the default separation is zero (so not 3d).

    Blender 2.5 svn build from graphicall.org clearly shows a control for eye distance :)
