Re: [Closed REQ 6258]: question

If you have data that fit in some sort of grid -- N rows, M columns, NxM data points -- then it's very simple: use a MESH. If (since) the rows and columns are lined up with the x and y axes, it's even simpler. For example, here's a MESH that represents the function z(x,y) = x + y^2 as x and y go from -1 to 1, x in 5 steps, y in 3 steps. The comments, line breaks, and so on are just for readability. All you need is to separate items with blanks (no commas). MESH 5 3 # First row of 5 vertices: -1 -1 0 # x y z -.5 -1 .5 0 -1 1 .5 -1 1.5 1 -1 2 # another row... -1 0 -1 -.5 0 -.5 0 0 0 .5 0 .5 1 0 1 # last row... -1 1 0 -.5 1 .5 0 1 1 .5 1 1.5 1 1 2 If the data aren't arranged on some sort of rectangularly-connected grid, but have the form of some function z(x,y) on scattered points in the x-y plane, you can use scatter2graph (from ftp://ftp.geom.umn.edu/pub/software/scatter2graph.tar.Z ) to take the data and make a surface out of them that's readable by geomview. Hope this helps. Stuart Levy
