Public Member Functions

 ChCollisionSystemDistributed (ChParallelDataManager *dm, ChDistributedDataManager *ddm)
 
virtual void Add (ChCollisionModel *model) override
 Adds the collision model to the collision system and creates a mapping entry from the associated body to its collision shapes.
 
virtual void Remove (ChCollisionModel *model) override
 Deactivates the body in the data manager of chrono::parallel and marks the space as free.
 
virtual void GetOverlappingAABB (custom_vector< char > &active_id, real3 Amin, real3 Amax) override
 Set each entry of active_id to true if the AABB of the shape with that index overlaps the given AABB.
 
- Public Member Functions inherited from chrono::collision::ChCollisionSystemParallel
 ChCollisionSystemParallel (ChParallelDataManager *dc)
 
virtual void Clear (void) override
