Direct Volume Rendering

Direct Volume Rendering

The second major technique for visualising scalar fields is known as Direct Volume Rendering or DVR. Inevitably, the
question arose whether topological techniques could be integrated into DVR, so we did so:

Another line of inquiry involved using statistics such as mean and standard deviation to enable low-resolution progressive DVR:

Subsequently, my previous work on trilinear interpolation caused me to collaborate on acceleration techniques for real-time
DVR:

and on differential histogram tables for accelerating time-varying isosurfaces:

Most recently, this line of interest involved applying DVR techniques with trilinear interpolation to bivariate fields (Also presented at ACM SIGGRAPH 2017):
