He considers the question of determining necessary and sufficient conditions for a compact set $C$ to pass through a closed interval (in 2D) and an analogous question in 3D. He considers nonconvex sets, and ends with a nice conjecture. But, again, this seems not to be directly addressing the (interesting!) question you raise. | |
