Member Function Documentation

void chrono::collision::ChCollisionSystemParallel::Add ( ChCollisionModel model)
virtual

Adds a collision model to the collision engine (custom data may be allocated).

Implements chrono::collision::ChCollisionSystem.

virtual void chrono::collision::ChCollisionSystemParallel::Clear ( void  )
virtual

Clears all data instanced by this algorithm if any (like persistent contact manifolds).

Implements chrono::collision::ChCollisionSystem.

void chrono::collision::ChCollisionSystemParallel::Remove ( ChCollisionModel model)
virtual

Removes a collision model from the collision engine (custom data may be deallocated).

Implements chrono::collision::ChCollisionSystem.

virtual void chrono::collision::ChCollisionSystemParallel::ReportContacts ( ChContactContainer mcontactcontainer)
virtual

After the Run() has completed, you can call this function to fill a 'contact container', that is an object inherited from class ChContactContainer.

For instance ChSystem, after each Run() collision detection, calls this method multiple times for all contact containers in the system, The basic behavior of the implementation is the following: collision system will call in sequence the functions BeginAddContact(), AddContact() (x n times), EndAddContact() of the contact container. But if a special container (say, GPU enabled) is passed, a more rapid buffer copy might be performed).

Implements chrono::collision::ChCollisionSystem.

virtual void chrono::collision::ChCollisionSystemParallel::ReportProximities ( ChProximityContainer mproximitycontainer)
virtual

After the Run() has completed, you can call this function to fill a 'proximity container' (container of narrow phase pairs), that is an object inherited from class ChProximityContainer.

For instance ChSystem, after each Run() collision detection, calls this method multiple times for all proximity containers in the system, The basic behavior of the implementation is the following: collision system will call in sequence the functions BeginAddProximities(), AddProximity() (x n times), EndAddProximities() of the proximity container. But if a special container (say, GPU enabled) is passed, a more rapid buffer copy might be performed).

Implements chrono::collision::ChCollisionSystem.

void chrono::collision::ChCollisionSystemParallel::Run ( )
virtual

Removes all collision models from the collision engine (custom data may be deallocated).

Run the algorithm and finds all the contacts. (Contacts will be managed by the Bullet persistent contact cache).
