I saw a thread a while back about using a program called World Wind which contains NASA satelite images and using it to generate terrains in Vue. No details were given as to how this was done and I'm wondering if it was just an idea someone had had but hadn't actually tried it. Is anyone out there actually doing this? The reason I am asking is that I have seen World Wind on the cover disc of PC Pro and will get it if I can use it in conjunction with Vue (4). Thanks, Kevin
