Notations for the derivation (Inlay). A point is either lit (a) or shadowed (b, c). In the latter case, we further distinguish between penumbra (b) and umbra (c), depending on whether the light source is only partially or completely hidden.

To close the remaining gaps, the straight line at the right-hand side (A), a circular arc interpolation is performed automatically using the center of gravity of the contour as the center of the circle (B). For the radius, linear interpolation is used from r1 to r2. The repaired contour is presented in (C)

Images show volume data that consist of billions of voxels rendered with our dynamic sparse octree approach. Our algorithm achieves real-time to interactive rates on volumes exceeding GPU memory capacity by far, tanks to efficient streaming and ray-casting solutions. Basically, the volume is only used at the resolution that is needed to produce the final image. Besides the gain in memory and speed, our rendering provides is inherently anti-aliased

Our new rendering method using ellipsoids with fixed shape to show the fibre orientations in the cross section of an infarcted heart, which was scanned 28 days after the infarct. We also tracked fibres from two different seeding areas. The resulting fibres were rendered as thin tubes and RGB colouring of the fibre orientation was used.
