Webreﬁnement algorithms. We will need four different data structures: two for tensor-product B-splines, and two for hierarchical B-splines. The ﬁrst two-structures regard the computation of tensor-product B-splines. We assume that, for each level ‘, we have a mesh structure with all the information of the rectilinear grid G‘, and a space WebIn this module, we'll discuss the lowest level of our hierarchical motion planner, which is the local planner. As a reminder, the local planner is the portion of the hierarchical planner that executes the maneuver requested by the behavior planner in a collision-free, efficient, and comfortable manner.
