Problem 25: Polyhedral Surface Approximation
- How efficiently can one compute a polyhedral surface
that is an
ε-approximation of a given triangulated surface in
- Mitchell [?]
- Partial and Related Results
- It is NP-hard to obtain the minimum-facet surface
separating two nested convex polytopes [DG97],
polynomial-time approximation algorithms are known
for this case, and for separating two terrain surfaces,
achieving factors within O(1) or O(log n) of optimal.
However, no polynomial-time approximation results
are known for general surfaces.
