Marius Kintel 1d66d2154b Filter empty children before performing minkowski sum. Fixes #1196 2015-01-29 18:35:12 -05:00
Marius Kintel 083bf4313f Allow the state to track cache lookup preference. This is important to allow lookups to prefer Nef polyhedrons in cases where PolySet->Nef fails due to zero triangles. Fixes #1027 2015-01-20 16:03:31 -05:00

Marius Kintel daf5a169dc Refactored Nef_nary_union optimization 2014-02-05 23:27:04 -05:00
Oskar Linde 2e6196761a Performance: Speed up CGAL n-ary union 
By utilizing CGAL::Nef_nary_union_3, n-ary union of many objects becomes significantly
faster (more than twice as fast in a test of 20 objects).

A further optimization potential lies in sorting the unioned objects based on proximity.
