Great stuff indeed, Soeren! > > Curiosity: how much faster is this compared to v.delaunay or likewise?
To me, it's not so much the speed that matters but functionality. VTK's 2D Delaunay has a very useful "alpha" threshold setting to constrain the triangle (by maximum triangle size). In addition, it's capable of fitting a plane of reference through the data points and does not assume that they lie perfectly in the X-Y plane. This gives much better results for point clouds that describe e.g. micro relief on a slope. You can try this already, even without the VTK bridge: just export some 3D points to VTK, load into ParaView (3.6) and choose Delaunay 2D from the "Filter" menu. Now, if only we had a simple way of getting VTK data back into GRASS...
