cspace_separating_plane.h File Reference

Detailed Description

This file is used in our C-IRIS algorithm and will be used in our C-Space path certifier, which certifies collision-free region in the configuration space, by finding separating planes for each pair of geometry over all configurations in a C-space region.

For the detailed algorithm please refer to the paper

Certified Polyhedral Decompositions of Collision-Free Configuration Space
by Hongkai Dai*, Alexandre Amice*, Peter Werner, Annan Zhang and Russ Tedrake.
