Videotutorial: Anaglyphic 3D rendering


Learn how to easily set up and render anaglyphic 3D images with Blender in this videotutorial.

I have made a tutorial that teaches people how to use the Blender setreo 3d addon.

I believe that this is important to the comunity because setreo 3d can be done in Blender without any thrid party software! This is also usable with cycles and Blender internal.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. It's important to realize that its better to take the image for the red channel and convert the RGB to gray-scale and feed that into the red channel instead of just using the red channel of the source image. That way your anaglyph will have also the 'color information' of the other colors fed into the red channel of the resulting anaglyph.

    I've been working with the (cheap) loreo side-by-side viewer.  It's kind of like a cardboard View Master with no back, it costs about $3.00, and folds down for mailing.  I like the side-by-side setup because it doesn't change the image colors, but until now the tools I had for creating anaglyphs were pretty lousy, so I'll have to give this a try

    I don't know if this is covered in the video, but I have a tip I'd like to share: Managing the cameras and the renders for stereo can quickly get out of hand.  I use a stereo camera armature to manage three cameras (left, right, and center).  The head "bone" of the armature is parent of the three cameras, and has a trackTo constraint on an unconnected bone named "CamTarget".  I have custom bone shapes for the rig base, camera head, and target bones, and the cameras and rig have thier own layer; this makes it easy to get the camera out of the way when I'm posing the scene, but I have to remember to re-activate the camera layer before doing a render.  .

    All of my set-up and composition work and my quick (test) renders are done by posing the camera rig with the center camera active.  Most of the time the left and right cameras are set as non-visible (using the outliner), so they don't get in my way. 

    When I'm happy with the results, I render the sequence two more times, hopefully remembering to activate the left or right camera for each sequence.  I also have to remember to set the output directory to the appropriate directories for the left and right cameras, so it's fairly easy to use the VSE to position the frames together.

    I have a short clip of the reuslts on youtube at

    • I'll second the Loreo viewer, I've got two sizes, one for 5"-7" images and the other for 10"-15" images suitable for use with a computer screen.  Your example shows off the 3D effect beautifully.

  3. i did a project in blender using anaglyph 3d last year. now i've got a shiny new 3dtv and i'm stoked to try making some shutter glasses 3d content! as far as formats go, it feels like a bit of a wild west situation though. one format seems to be side-by-side horizontally compressed images, but then you lose half your horizontal resolution. short of authoring your own blu-ray, is there a way to get full hd 3d content to display on active-3d tvs?

      I'm no expert, but on my 3DTV at least, the 1080p 3D movies I've... *cough* obtained are side-by-side but formated so as to be twice the width. The only bad news is that these videos are terribly compressed and motion blur is awful. Still a 10GB file, though. >_<
