[vtkusers] Re: hardware stereo volume rendering

[Dr. Dan White]

Hi Steffen,

I just got stereo working using VTK with the MayaVi front end. I am 
using stereographics crystaleyes hardware. In the Option menu of the 
mavavi VTK actor viewer window (the graphics window) there is an 
option in ConfigureRenderWwindow for Dresden stereo. Remember to also 
turn on StereoRenderOn. Hope that might work for you.

Also a question to the VTK gurus.............
When using texture mapping for stereo volume rendering, everything 
works great...if a little slowly- but with ray casting volume stereo 
rendering, the left and right rendered images seem to be swapped, but 
the border lines are not.?????

Anyone have an Idea why this might be happening...is it a bug in the 
VTK ray casting code?

Cheers

Dan
