In various sampling methods developed for estimation of failure probability, there are stages at which it is useful to estimate the extent of the domain of basic variables which has already been covered by sampling points. This information is helpful for adaptive update of the sampling strategy. We propose using a geometrical representation of the explored part of the domain by a convex hull. Once performed, we may target at exploration sampling, as well as using convex hull for estimation measure of the (un)explored domain. Whereas in problems which feature just a few random variables we are able to set up convex hull bounding the given set of points precisely, in problems of high dimensions we only can assemble convex hull from a limited number of hyperplanes bounding a set of points. This paper compares various approximation to convex hull in small to moderate domain dimensions.
