From: Etienne Grossmann To: JH Cc: graphics at octave dot org, etienne@cs.uky.edu Date: Mon, 26 Sep 2005 10:18:24 -0400 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 On Fri, Sep 23, 2005 at 04:27:45PM +0200, JH wrote: # Hello, # # I've just came into this news server and those octave's forums, so # please excuse me if my question is stupid. # # I'm searching for replace my matlab needs by octave, whose I found very # powerful ; I've checked, and lots of my programs written with matlab # would still work with octave, with some minor modifications. # # But there is still a problem, about plotting with octave.
