I have a similar problem that I need to solve. I need to be able to visualise a Geological fault in 3-D. I need to interpolate the x y z data and then visualise it on its side. Im not sure if or is capable of doing this? Thanks On Tue, Dec 3, 2013 at 4:02 AM, Mercutio Florid wrote: > I want to

I want to map out a mostly flat area of land, 300 meters on a side.  I want to make (x,y,z) triples where x and y vary between -150 and 150 and there is just one z value. Eventually I will try to use graphics to actually draw this, but my first problem is that I need to get 90601 values by i
