ReVolVR

Rendering von Volumendaten in Virtual Reality mit der HTC Vive

Direct Volume Rendering (DVR) techniques are used to visualize surfaces from 3D volume data sets without computing a 3D geometry. Several surfaces can be classified using a transfer function by mapping data values to color and opacity (RGBalpha). To find a good transfer function with the aim to separate specific structures from the volume data set is in general a manual, exhausting, and time-consuming procedure and requires detailed knowledge of the data and the image acquisition technique. We develop a new interactive Virtual Reality (VR) application to load, modify and save the transfer function in real time while continuously interacting and rendering the 3D volume through GPU-based ray casting shader.
