The Property Test operator tests if particles satisfy property-based conditions.
Property List: the list of testable particle properties.
Test TRUE if property is: various conditions that will be used in the test.
Search radius: the neighbor search radius.
Look ahead: the search will be conducted at a location this far along the particle’s velocity vector.
Sweep test: searches for neighbors along each particle’s entire trajectory, not just the particle’s starting position.
Test by ID: controls whether only bindings which have a matching ID will be tested.
ID: the ID to match.
TRUE if all broken: controls whether the test condition will be satisfied if all bindings are broken.
