[vtkusers] VTk Stereo - Help Rendering Left & Right Eye Seperately

[Teek]

Ahhh I should've been more clear. But I'm using zSpace as my display which
handles the stereoscopic rendering fine if I use Crystal Eyes.

Would it be possible for me to have 2 renderers on top of each other in one
window, and then use the front and back buffers for each renderer?

For my use, I can't actually use just the center of the two eyes. I would
need to render each eye separately or set the camera for each eye.

zSpace has an example of rendering in OpenGL in which they render the scene
twice using GL_FRONT_LEFT and GL_BACK_LEFT buffers, respective to each eye.
I'm trying to recreate that with VTK because VTK implies volume rendering
significantly.
