Broad Phase: Brute Force Broad Phase

BruteForceBroadPhase is a broad phase component, which is used in a Collision Detection pipeline.

The method is based on the comparison of the overall bounding volumes of objects to determine if they are in collision or not. This test is very exhaustive because of its pairwise checks. In SOFA, the proposed bounding volumes are commonly Axis-Aligned-Bounding-Box (AABB).

Since, the bounding volumes are very simple (AABB), the tests are very fast for a few collision models. A more advanced method must be selected for simulations involving a high number of objects.

A parallel implementation (ParallelBruteForceBroadPhase) can be found in the plugin MultiThreading.
