Real-time Volume Rendering Interaction in Virtual Reality
Volume visualization using Direct Volume Rendering
(DVR) techniques is used to view information inside 3D volumetric data. Data is
classified using a transfer function to emphasize or filter some parts of
volumetric information, such as that from Computed Tomography (CT) or Magnetic
Resonance Imaging (MRI). In this paper, we introduced an application for
real-time volume rendering interaction with 1D transfer functions using Virtual
Reality (VR) technology based on the Oculus Rift headset and Oculus Touch
controllers. Resulting images were visualized stereoscopically at 60 frames per
second using a ray-casting shader, which works based on Graphics Processing
Unit (GPU). To evaluate the system, 20 participants interacted with the
application to complete three tasks, including a free viewpoint scan, clipping
planes renderer, and an editable transfer function in the virtual environment.
Then, a survey was carried out using a questionnaire to gather data. Findings
showed that the average usability score for the application was 87.54, which
suggested that it was highly usable
