Hi Burlen, I have upgraded to the AMD drivers. Thanks for the hint. It has improved the situation a bit.
Furthermore, I created the wavelet source. When selecting "volume" representation, I do see a three 3 picture, in all 5 volume rendering mode (smart, raycast and texture mapping, ray cast only, texture mapping only, GPU based). The picture a rather fuzzy, but then I don't know what I'm supposed to see here. The good news is that the openGL errors I had before when displaying a wavelet, now have gone. The situation with my own cube, though, has unchanged. unfortunately. The cube disappears in "volume" representation node, also when I re-inserted scalar values for each of the 8 vertices.
