OCT Visualization in Virtual Reality¶
Virtual reality (VR) offers new opportunities for the display of volumetric datasets by harnessing the user’s entire field of view. VR headsets have high resolution and framerate requirements, however, that are incompatible with the rapid rendering of densely-sampled volumetric scenes. We developed GPU-optimized algorithms for stereoscopic rendering of volumetric datasets at up to 90 fps as needed for immersive VR experiences. With these algorithms, we demonstrated viewing of and interaction with live optical coherence tomography volumes with VR.
