Here's the problem:
I have data in the form of a four-tuple: (x,y,z,d), where (x,y,z) correspond to a point in 3-space, and d, some data value. I have a data set of these points, and I would like to graph them.
What I don't know how to do is to make a grid for this aribrtrarily spaced data. It would seem that after I interpolate the data some how, I then should use SurfaceGraphics.
Any pointers to other sites, and suggestions would be appreciated.
