◆ claimCollisionObject()

std::shared_ptr< CollisionObject > dart::collision::CollisionDetector::claimCollisionObject ( const dynamics::ShapeFrame shapeFrame)
protectedinherited

Claim CollisionObject associated with shapeFrame.

New CollisionObject will be created if it hasn't created yet for shapeFrame.

◆ cloneWithoutCollisionObjects()

std::shared_ptr< CollisionDetector > dart::collision::DARTCollisionDetector::cloneWithoutCollisionObjects ( ) const
overridevirtual

Create a clone of this CollisionDetector.

All the properties will be copied over, but not collision objects.

Implements dart::collision::CollisionDetector.

◆ collide() [1/2]

bool dart::collision::DARTCollisionDetector::collide ( CollisionGroup group,
const CollisionOption option = CollisionOption(false, 1u, nullptr),
CollisionResult result = nullptr 
)
overridevirtual

Perform collision check for a single group.

If nullptr is passed to result, then the this returns only simple information whether there is a collision of not.

Implements dart::collision::CollisionDetector.

◆ collide() [2/2]

bool dart::collision::DARTCollisionDetector::collide ( CollisionGroup group1,
CollisionGroup group2,
const CollisionOption option = CollisionOption(false, 1u, nullptr),
CollisionResult result = nullptr 
)
overridevirtual

Perform collision check for two groups.

If nullptr is passed to result, then the this returns only simple information whether there is a collision of not.

Implements dart::collision::CollisionDetector.

◆ createCollisionGroup() [1/4]

std::unique_ptr< CollisionGroup > dart::collision::DARTCollisionDetector::createCollisionGroup ( )
overridevirtual

Create a collision group.

Implements dart::collision::CollisionDetector.

◆ createCollisionGroup() [2/4]

virtual std::unique_ptr<CollisionGroup> dart::collision::CollisionDetector::createCollisionGroup
virtual

Create a collision group.

Implements dart::collision::CollisionDetector.

◆ createCollisionGroup() [3/4]

template<typename... Args>
std::unique_ptr< CollisionGroup > dart::collision::CollisionDetector::createCollisionGroup ( const Args &...  args)
inherited

Create a collision group from any objects that are supported by CollisionGroup::addShapeFramesOf().

The objects can be any of ShapeFrame, std::vector<ShapeFrame>, CollisionGroup, BodyNode, and Skeleton.

Note that this function adds only the ShapeFrames of each object at the moment that this function is called. Any later addition to or removal of the ShapeFrames that are attached to these objects will NOT be noticed.

◆ createCollisionGroup() [4/4]

template<typename... Args>
std::unique_ptr< CollisionGroup > dart::collision::CollisionDetector::createCollisionGroup ( typename...  Args)

Create a collision group from any objects that are supported by CollisionGroup::addShapeFramesOf().

The objects can be any of ShapeFrame, std::vector<ShapeFrame>, CollisionGroup, BodyNode, and Skeleton.

Note that this function adds only the ShapeFrames of each object at the moment that this function is called. Any later addition to or removal of the ShapeFrames that are attached to these objects will NOT be noticed.

◆ createCollisionGroupAsSharedPtr() [1/2]

std::shared_ptr< CollisionGroup > dart::collision::CollisionDetector::createCollisionGroupAsSharedPtr ( )
inherited

Helper function that creates and returns CollisionGroup as a shared_ptr.

Internally, this function creates a shared_ptr from unique_ptr returned from createCollisionGroup() so the performance would be slighly worse than using std::make_unique.

◆ createCollisionGroupAsSharedPtr() [2/2]

template<typename... Args>
std::shared_ptr< CollisionGroup > dart::collision::CollisionDetector::createCollisionGroupAsSharedPtr ( const Args &...  args)
inherited

Helper function that creates and returns CollisionGroup as shared_ptr.

◆ distance() [1/2]

double dart::collision::DARTCollisionDetector::distance ( CollisionGroup group,
const DistanceOption option = DistanceOption(false, 0.0, nullptr),
DistanceResult result = nullptr 
)
overridevirtual

Get the minimum signed distance between the Shape pairs in the given CollisionGroup.

The detailed results are stored in the given DistanceResult if provided.

The results can be different by DistanceOption. By default, non-negative minimum distance (distance >= 0) is returned for all the shape pairs without computing nearest points.

Implements dart::collision::CollisionDetector.

◆ distance() [2/2]

double dart::collision::DARTCollisionDetector::distance ( CollisionGroup group1,
CollisionGroup group2,
const DistanceOption option = DistanceOption(false, 0.0, nullptr),
DistanceResult result = nullptr 
)
overridevirtual

Get the minimum signed distance between the Shape pairs where a pair consist of two shapes from each groups (one from group1 and one from group2).

Note that the distance between shapes within the same CollisionGroup are not accounted.

The detailed results are stored in the given DistanceResult if provided.

The results can be different by DistanceOption. By default, non-negative minimum distance (distance >= 0) is returned for all the shape pairs without computing nearest points.

Implements dart::collision::CollisionDetector.

◆ getFactory()

CollisionDetector::Factory * dart::collision::CollisionDetector::getFactory ( )
staticinherited

Returns the singleton factory.

◆ getStaticType()

const std::string & dart::collision::DARTCollisionDetector::getStaticType ( )
static

Get collision detector type for this class.

◆ getType()

const std::string & dart::collision::DARTCollisionDetector::getType ( ) const
overridevirtual

Return collision detection engine type as a std::string.

Implements dart::collision::CollisionDetector.

◆ notifyCollisionObjectDestroying()

void dart::collision::CollisionDetector::notifyCollisionObjectDestroying ( CollisionObject object)
protectedvirtualinherited

Notify that a CollisionObject is destroying. Do nothing by default.

Reimplemented in dart::collision::BulletCollisionDetector.

◆ raycast()

bool dart::collision::CollisionDetector::raycast ( CollisionGroup group,
const Eigen::Vector3d &  from,
const Eigen::Vector3d &  to,
const RaycastOption option = RaycastOption(),
RaycastResult result = nullptr 
)
virtualinherited

Performs raycast to a collision group.

Parameters
[in]groupThe collision group the ray will be casted onto.
[in]fromThe start point of the ray in world coordinates.
[in]toThe end point of the ray in world coordinates.
[in]optionThe raycast option.
[in]resultThe raycast result.
Returns
True if the ray hit an collision object.

Reimplemented in dart::collision::BulletCollisionDetector.

◆ refreshCollisionObject()

void dart::collision::DARTCollisionDetector::refreshCollisionObject ( CollisionObject object)
overrideprotectedvirtual

Update the collision geometry of a ShapeFrame.

Implements dart::collision::CollisionDetector.
