Good afternoon list,
Please forgive me this one time error should this have been asked

I am trying to figure out how to get clearer plots out of Octave. I am
using this m-file{http://www.thumbprintpro.com/math/fib.m}, and it is
giving me the following output:
http://www.thumbprintpro.com/math/OctaveOutPut.png . While this is
adequate, it is difficult to see that this is a 3d image, and compared
to this output from Matlab,
http://www.thumbprintpro.com/math/MatlabOutPut.png, it is easy to see my
frustration. I am trying to relieve my stress of having to log into my
schools slow remote desktops and do all of my math computations through
Octave, but the output is of such quality that I cannot insert that into
a report. Also, it took 15 minutes to generate that image where Matlab
took 15 seconds. I have been looking online for a replacement plotter
for use with Octave, but nothing I have found yet is working with
Windows. It could just be that I lack the necessary skills to compile
some of these packages, or the knowledge of how to insert them into
Octave, I am unsure. Can someone point me in the right direction to
getting opengl plots for Octave under Windows?

To get a somewhat improved 3d feeling without the need to install an
additional package
you can use
backend("fltk")
before you call your script and then substitute your simple isosurface call
to
[F, v, c] = isosurface (x, y, z, f, 1.1, x);
p = patch ("Faces", F, "Vertices", v, "FaceVertexCData", c, \
"FaceColor", "interp", "EdgeColor", "none");
colormap(copper(256));
shading interp
view(30,30)
this adds some shading in x direction.
Btw, jhandles gives at the moment the best results, because you can set
lights but
I have problems at the moment to install it, so I cannot directly compare.
