Hello,
I wonder how to draw torus in Geogebra.
Now I have define a variable s, and define a curve as
CurveCartesian((2+0.5cos(t))cos(s),(2+0.5cos(t))sin(s),0.5sin(t),t,0,2π)
However, I want the variable s also defined in a range as variable t, rather than a independent variable.
That means, I need curve functions dependent on two variables.
How to do this?
Thank you.

See in materials https://www.geogebra.org/se...
for example:https://www.geogebra.org/m/aR4FkzaD
they are surface()
