Re: Octave plotter for 3D shading plots ?

  Hi JH,

I wrote some code to have octave produce vrml (virtual reality ml)
code and pass it to a vrml browser, freewrl, w/ which you can move
your viewpoint and take snapshots. It's a little clunky and I don't
know that anyone else uses it, but it's in octave-forge and you can
call a mesh-like function

  vmesh (x,y,z) or vmesh(z)


  Hth,

  Etienne
