Hi, you want to draw a curve on a rectangle, identifying opposite sides? Well you can do this e.g. using Mod and ParametricPlot. Here is an example where we use the unit square {{0,0},{0,1},{1,1},{1,0}} and the square function: ParametricPlot[{Mod[t, 1], Mod[t^2, 1]}, {t, 0, 4}] Daniel LordBeotian wrote: > I want to plot a curve on a flat torus (i.e. the square with > identified opposite edges) so i would like mathematica to join the > points of the curve in a way that respect the torus topology.
