This is demo version of Drishti VR (compiled on Windows 10 using Qt 5.4.1 and libQGLVIewer 2.6.1)

05/April/2018
Version 0.1

Drishti VR
This version should work on HTC Vive as well as Oculus Rift.

Once (Drishti imported) volume is loaded in the program and appropriate transfer function chosen, select VR Mode under top level Mode menu.

The two controllers will be seen as blue and yellow.

Use blue controller (with trigger pressed) for translations and yellow controller for rotations.

The menu button on either controllers will toggle the menu in VR. Currently only a few options are available. Move the sliders using yellow controller trigger. Press RESET on the menu in VR using yellow controller trigger to reset the model.


Please send your comments on Drishti User Group.

I hope you enjoy the demo.
