Currently the dilation of a polyhedron is done by computing the new double description from the new vertices.
With #28880 at hand, we can specify both Vrep and Hrep and the backend will use both (if available) or the shorter description. Either way, this will improve performance of polyhedra with many vertices but few facets (e.g. a hypercube).
Before this ticket we had the following timings:
With this ticket we have:
Note that for the last timing, the choice of only specifying Vrep was already good (at least for backend
ppl
). So with the new setup, thinks take a bit more time, asdilation
computes the new Hrep, whichppl
discards then.CC: @jplab @LaisRast
