Option to get better surfaces drawing using more points
Declined
Here is the graph of z = cos(x y) in GeoGebra. The output is quite rough even the option "Quality" selected
The graph of the same function generated with the defaults options in Mathematica 9:
As bad as GeoGebra output. But, Mathematica has an option to improve the quality of the graph:
Yes, you have sacrifice performance, but you get a much better image, suitable for use in Calculus textbooks, for instance.
My suggestion: implement em GeoGebra such option to increase the number of points used to improve the quality of the graph.

Sorry, it's not as easy as it sounds to do that.
What you can do in the meantime is to split the surface up, for example https://www.geogebra.org/cl...
