can anyone have a look at this: http://www.husser.de/heightmap.zip
You can spin around with mouse, move around with left/right/up/down key and move up/down with A/Y.
There is a strange problem with the texture. I don’t know how to explain, so please d/l and start it.
NOTE: I use the new VBO Extension, so you will have the latest beta drivers to be installed!
