Stereoscopic rendering #1165

It would be nice if tomviz would support stereoscopic rendering.

Preferably using different methods that can be chosen depending on what kind of 3D hardware is available. E.g.

OpenGL quad buffering with shutter glasses.
Anaglyph using red-cyan glasses (cheap, doesn't require any hw support). E.g. https://threejs.org/examples/webgl_effects_anaglyph.html
Stereo support for 3D TV's and things like "google cardboard", where the screen is split in half, left part for left eye and right part for right eye, and the display hardware takes care of the rest. E.g. https://threejs.org/examples/webgl_effects_stereo.html

@jabl that's a great idea. It would help the promotion and outreach of 3D visualization in science. With the 1.0 release we are now focusing effort to broaden the user base. When we return to new feature development we will look into this. Thanks for the idea.

Good to hear. Is there anything I can do to help get this done? I can afford to spend some work hours on this.

There seems to be (undocumented?) command-line options --stereo and --stereo-type= that implement this. This seems to be coming from paraview, as there is not mention of stereo anywhere in the tomviz source tree.

I wonder, would it be possible to change the stereo enabling and type from some widget in the application? I guess adding command-line options is difficult for windows/mac users who launch the application by clicking some icon rather than from the shell.
