handles the stereoscopic rendering fine if I use Crystal Eyes.<br>
<br>
Would it be possible for me to have 2 renderers on top of each other in one<br>
window, and then use the front and back buffers for each renderer?<br>
<br>
For my use, I can't actually use just the center of the two eyes. I would<br>
need to render each eye separately or set the camera for each eye.<br>
<br>
zSpace has an example of rendering in OpenGL in which they render the scene<br>
twice using GL_FRONT_LEFT and GL_BACK_LEFT buffers, respective to each eye.<br>
I'm trying to recreate that with VTK because VTK implies volume rendering<br>
significantly.<br>
