The diameter of a set P of n points in ${\mathbb R}^d$ is the maximum Euclidean distance between any two points in P. If P is the vertex set of a 3–dimensional convex polytope, and if the combinatorial structure of this polytope is given, we prove that, in the worst case, deciding whether the diameter of P is smaller than 1 requires Ω(n log n) time in the algebraic computation tree model. It shows that the O(n log n) time algorithm of Ramos for computing the diameter of a point set in ${\mathbb R}^3$ is optimal for computing the diameter of a 3–polytope. We also give a linear time reduction from Hopcroft's problem of finding an incidence between points and lines in ${\mathbb R}^2$ to the diameter problem for a point set in ${\mathbb R}^7$.
