Yes, that is a good summary. > Question: I've read good things about a "TriD" plotting package, which (among > other things) lets you rotate & zoom the a 3d plot with the mouse.

TriD is a mixed bag. It is a brilliant code that generates direct OpenGL calls to render 3-D plots, and it is very fast. But it is very hard ot create publication-quality output from TriD. It is also very difficult to modify the code, which is quite contorted and not well documented. I recommend PDL::Graphics::Gnuplot for static 3-D plotting with adjustable perspective and scene. Gnuplot is perhaps 10x slower than TriD, but its output is publication quality, and it is easier to manipulate. _______________________________________________ Perldl mailing list [email protected] http://mailman.jach.hawaii.edu/mailman/listinfo/perldl
