Just time this evening for a quick update: I finished my 3D Gaussian convolution on my generated data set - the attached image has clearly visible joins in it, these are to make sure my segmented approach of processing big data sets works correctly. The are easily removed by overlapping the non-boundary segments. The colours are based on my transfer function and don't reflect the underlying data accurately yet. It renders the volume at around 40fps.
