Member Function Documentation

◆ addCollisionObject()

virtual void collision_detection_bullet::BulletBVHManager::addCollisionObject ( const CollisionObjectWrapperPtr & cow )

pure virtual

Add a collision object to the checker.

All objects are added as static objects initially. Use the setContactRequest method for defining which collision objects are moving.

Parameters

cow	The tesseract bullet collision object

Implemented in collision_detection_bullet::BulletCastBVHManager, and collision_detection_bullet::BulletDiscreteBVHManager.

◆ clone()

BulletBVHManagerPtr collision_detection_bullet::BulletBVHManager::clone ( ) const

Clone the manager.

This is to be used for multi threaded applications. A user should make a clone for each thread.

◆ contactTest()

virtual void collision_detection_bullet::BulletBVHManager::contactTest	(	collision_detection::CollisionResult &	collisions,
		const collision_detection::CollisionRequest &	req,
		const collision_detection::AllowedCollisionMatrix *	acm,
		bool	self
	)

pure virtual

Perform a contact test for all objects.

Parameters

collisions	The Contact results data
req	The collision request data
acm	The allowed collision matrix
self	Used for indicating self collision checks

Implemented in collision_detection_bullet::BulletCastBVHManager, and collision_detection_bullet::BulletDiscreteBVHManager.

◆ disableCollisionObject()

bool collision_detection_bullet::BulletBVHManager::disableCollisionObject ( const std::string & name )

Disable an object.

Parameters

name	The name of the object

Returns: true if successfully disabled, otherwise false.

Definition at line 125 of file bullet_bvh_manager.cpp.

◆ enableCollisionObject()

bool collision_detection_bullet::BulletBVHManager::enableCollisionObject ( const std::string & name )

Enable an object.

Parameters

name	The name of the object

Returns: true if successfully enabled, otherwise false.

Definition at line 113 of file bullet_bvh_manager.cpp.

◆ getActiveCollisionObjects()

const std::vector< std::string > & collision_detection_bullet::BulletBVHManager::getActiveCollisionObjects ( ) const

Get which collision objects are active.

Returns: A vector of collision object names

Definition at line 169 of file bullet_bvh_manager.cpp.

◆ getCollisionObjects()

const std::map< std::string, CollisionObjectWrapperPtr > & collision_detection_bullet::BulletBVHManager::getCollisionObjects ( ) const

Definition at line 192 of file bullet_bvh_manager.cpp.

double collision_detection_bullet::BulletBVHManager::getContactDistanceThreshold ( ) const

Get the contact distance threshold.

Returns: The contact distance

Definition at line 187 of file bullet_bvh_manager.cpp.

◆ hasCollisionObject()

bool collision_detection_bullet::BulletBVHManager::hasCollisionObject ( const std::string & name ) const

Find if a collision object already exists.

Parameters

name	The name of the collision object

Returns: true if it exists, otherwise false.

Definition at line 94 of file bullet_bvh_manager.cpp.

◆ removeCollisionObject()

bool collision_detection_bullet::BulletBVHManager::removeCollisionObject ( const std::string & name )

Remove an object from the checker.

Parameters

name	The name of the object

Returns: true if successfully removed, otherwise false.

Definition at line 99 of file bullet_bvh_manager.cpp.

◆ setActiveCollisionObjects()

void collision_detection_bullet::BulletBVHManager::setActiveCollisionObjects ( const std::vector< std::string > & names )

Set which collision objects are active.

Parameters

names A vector of collision object names

Definition at line 153 of file bullet_bvh_manager.cpp.

◆ setCollisionObjectsTransform()

void collision_detection_bullet::BulletBVHManager::setCollisionObjectsTransform	(	const std::string &	name,
		const Eigen::Isometry3d &	pose
	)

Set a single static collision object's tansform.

Parameters

name	The name of the object
pose	The tranformation in world

Definition at line 137 of file bullet_bvh_manager.cpp.

◆ setContactDistanceThreshold()

void collision_detection_bullet::BulletBVHManager::setContactDistanceThreshold ( double contact_distance )

Set the contact distance threshold for which collision should be considered through expanding the AABB by the contact_distance for all links.

Parameters

contact_distance The contact distance
