am I wrong or the x and y axis are exchanged?
I have downloaded smath studio a few days ago and made some examples to be more familiar with the program. Today I have tested 3D plot and found 2 strange behaviour.
First on 3D plot x and y seems to be swapped
Second the same formula plotted by 3D plot and by 3D graph give a different view

The SMath built-in 3D plot is left-handed, the 3DPlot Region is right-handed (being able to choose, I prefer the 2nd but is matter of taste) Good

Thanks for answering.
But the sin function is defined with y as variable and the step function is defined with x as variable. On the 3D plot the sin is along the X axis and the step function along the Y one.

is there a version of a tutorial for dummies for this plugin? I tried to figure it out on my own but can't get it to work.

I just wanted to try and plot a sphere for fun. maybe next would be plot a line / plane and see where it intersects the sphere.

______________________________

AFAIK, as far as I have experimented, the Maxima 3d plot is for parametric unctions
and the style in example. It does not plot "volume 3D", it does not take stacked arguments. Up until my help: zap for the sphere and the cutting plane. The 3D Smath default plot is just for fun, nothing to do, no color ... These two may help using this Maxima plot.

Updated.

Changes:

- CreateMesh(): (u,v) can be skipped for the function;
- 3D Plot Region: began updating the code (draft version).

About 3D Plot. Unfortunately, the source code that I found requires significant improvement in order to display a family of graphs. I hope I have enough time and desire to bring this component to normal at last.
