Abstract

We present an algorithm to extract space curves, defined by differential invariants, at increasing scales. The algorithm uses an extension of the 3D Marching Lines that allows us to search for iso-surfaces and their intersections in spaces of arbitrary dimension. Specifically, we have implemented a 4D extension that we apply to track lines efficiently on iso-surfaces. We show that it automatically finds the connection order of singularities. As an example, we visualize the development of parabolic and crest lines across scale.
