Octave plotter for 3D shading plots ?

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. By default, I
think the official plotter of octave is gnuplot. But in despites the
qualitys of gnuplot, it is not why I'm expecting, specially in 3D plots
and shading surfaces. I can't afford to obtain the same display-like
results of "mesh" that I had with matlab. And visualisation after
rendering is impossible (you can't "rotate" with the mouse the mesh you
made)

Happily, gnuplot is not the only choice of plotter in octave, and that's
the point : I've read in this forum that there is many other plotters.

I don't want to begin a holy war, but I'm searching for the plotter who
would feed my needs at best, under Linux.
What I want do to is simple : easy plot in 2D (and figures exporting)
and moreover, plot 3D shading surface (in fact, like the way matlab does
with the command
"surface(X,Y,Z), shading interp;"


Could you help me ?


Thanks
