We conjecture that a convex polytope is uniquely determined up to isometry by its edge-graph, edge lengths and the collection of distances of its vertices to some arbitrary interior point, across all dimensions and all combinatorial types. We conjecture even stronger that for two polytopesandwith the same edge-graph it is not possible thathas longer edges thanwhile also having smaller vertex-point distances. We develop techniques to attack these questions and we verify them in three relevant special cases:andare centrally symmetric,is a slight perturbation of, andandare combinatorially equivalent. In the first two cases the statements stay true if we replaceby some graph embeddingof the edge-graphof, which can be interpreted as local resp. universal rigidity of certain tensegrity frameworks. We also establish that a polytope is uniquely determined up to affine equivalence by its edge-graph, edge lengths and the Wachspress coordinates of an arbitrary interior point. We close with a broad overview of related and subsequent questions.
