◆ RayHit() [1/2]
| bool chrono::collision::ChCollisionSystemBullet::RayHit | ( | const ChVector<> & | from, |
| const ChVector<> & | to, | ||
| ChCollisionModel * | model, | ||
| ChRayhitResult & | mresult, | ||
| short int | filter_group, | ||
| short int | filter_mask | ||
| ) | const |
Perform a ray-hit test with the specified collision model.
This version allows specifying the Bullet collision filter group and mask (see btBroadphaseProxy::CollisionFilterGroups).
◆ RayHit() [2/2]
| bool chrono::collision::ChCollisionSystemBullet::RayHit | ( | const ChVector<> & | from, |
| const ChVector<> & | to, | ||
| ChRayhitResult & | mresult, | ||
| short int | filter_group, | ||
| short int | filter_mask | ||
| ) | const |
Perform a ray-hit test with all collision models.
This version allows specifying the Bullet collision filter group and mask (see btBroadphaseProxy::CollisionFilterGroups).
◆ ReportContacts()
|
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()
|
overridevirtual |
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()
|
overridevirtual |
Run the algorithm and finds all the contacts.
(Contacts will be managed by the Bullet persistent contact cache).
Implements chrono::collision::ChCollisionSystem.
◆ SetNumThreads()
|
overridevirtual |
Removes all collision models from the collision engine (custom data may be deallocated).
Set the number of OpenMP threads for collision detection.
Reimplemented from chrono::collision::ChCollisionSystem.
