Hello everybody! I read that a ?new? graphic tool comes with grass5. It's called Nviz, and what the description said it looks pretty. I downloaded grass50b (linux binary). I work on RedHat 5.x, with Xfree3.x on a Intel Pentium PC, and wonder how I can make grass work with Nviz tool? Is it possible ? if yes, how? Thanx for your help karin
