◆ RayHit() [1/2]

virtual bool chrono::collision::ChCollisionSystemBulletParallel::RayHit ( const ChVector<> &  from,
const ChVector<> &  to,
ChCollisionModel model,
ChRayhitResult mresult 
) const
inlineoverridevirtual

Perform a ray-hit test with the specified collision model.

Currently not implemented.

Implements chrono::collision::ChCollisionSystem.

◆ RayHit() [2/2]

virtual bool chrono::collision::ChCollisionSystemBulletParallel::RayHit ( const ChVector<> &  from,
const ChVector<> &  to,
ChRayhitResult mresult 
) const
inlineoverridevirtual

Perform a ray-hit test with all collision models.

Currently not implemented.

Implements chrono::collision::ChCollisionSystem.

◆ ReportContacts()

void chrono::collision::ChCollisionSystemBulletParallel::ReportContacts ( ChContactContainer mcontactcontainer)
overridevirtual

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.

Implements chrono::collision::ChCollisionSystem.

◆ ReportProximities()

virtual void chrono::collision::ChCollisionSystemBulletParallel::ReportProximities ( ChProximityContainer mproximitycontainer)
inlineoverridevirtual

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.

Implements chrono::collision::ChCollisionSystem.

◆ Run()

void chrono::collision::ChCollisionSystemBulletParallel::Run ( )
overridevirtual

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).

Implements chrono::collision::ChCollisionSystem.
