Controlling quality of 3d plot

[Oz Nahum]

Hi,
I was wondering how I can get a better quality images with octave.
Here is an example of image produce with matlab
And the same code produced a terrible picture with octave

I would like to change the sampling rate of the slices, and also be able to
control the fonts displaying.

I use octave 3.0.5 on debian squeeze,
I attached also the code to produce the above plots

Thanks in advance for any help,
Oz.
