Approximate simulation from general sets; details are given in the text. At top left is a trefoil knot with points sampled uniformly from the path. Top right has the letters JSDA constructed from line segments, then embedded in \({\mathbb {R}}^{3}\). Points are then sampled uniformly according to lengths of the line segments. Bottom left has points sampled on the unit simplex according to a density \(\exp \left (-20 |{\mathbf {x}}-\left (\frac 1 3, \frac 1 3,\frac 1 3\right) |^{2}\right)\). The last plot shows points sampled uniformly from a hollow tube
