[Bf-committers] Multiview branch: which stereo 3-D displays/techniques to support?

[Sean Olson]

I personally am a big fan of cross eye - It does not require any equipment
and if you have the skill to do it it's super fast to check the 3d - Only
downside is extended viewing gives headaches, so keep it short!
 Additionally, youtube supports it!

header)

I also think Dr. Epilepsy sounds intriguing.
