I expect the difference in speed difference is largely due to octave writing a 
file that gnuplot must then read.

The difference between the Matlab and Octave figures is also primarily due to 
gnuplot.

I'm not a window's user, so I'm not sure it will work for you, but you can try 
the jhandles package.

Some isosurface examples are below.
