Abstract
Systems, methods, and other embodiments associated with determining whether geometries represented by geometry objects intersect are described. One example method recursively decomposes a higher order geometry (e.g., solid) into a set of lower order geometries (e.g., surfaces) and examines the lower order geometries, continuing the recursion until an intersection decision is reached. The example method includes accessing geometry objects and accessing a spatial index that stores MBVs associated with the geometry objects. The method includes extracting candidate pairs of intersecting features upon determining MBVs associated with the geometry objects intersect and providing the candidate features to a feature-feature logic. The method includes providing an intersection signal based on a features intersection signal provided by the feature-feature logic.
