Member Enumeration Documentation

◆ DataVariance

enum dart::dynamics::Shape::DataVariance

DataVariance can be used by renderers to determine whether it should expect data for this shape to change during each update.

Enumerator
STATIC
DYNAMIC_TRANSFORM	No data will ever change.
DYNAMIC_PRIMITIVE	The relative transform of the Shape might change.
DYNAMIC_COLOR	The primitive properties (such as x/y/z scaling) of the shape might change.
DYNAMIC_VERTICES	The coloring or textures of the shape might change.
DYNAMIC_ELEMENTS	Vertex positions of a mesh might change (this does not include adding or removing vertices) (this enum is not relevant for primitive shapes)
DYNAMIC	The number of elements and/or arrangement of elements might change (this includes adding and removing vertices) (this enum is not relevant for primitive shapes)

◆ ShapeType

Member Function Documentation

◆ addDataVariance()

void dart::dynamics::Shape::addDataVariance ( unsigned int _variance )

Add a type of variance to this shape.

All other variance types will remain the same.

◆ addObserver()

void dart::common::Subject::addObserver ( Observer * _observer ) const

protectedinherited

Add an Observer to the list of Observers.

◆ checkDataVariance()

bool dart::dynamics::Shape::checkDataVariance ( DataVariance type ) const

True iff this Shape has the specified type of DataVariance.

◆ computeInertia()

virtual Eigen::Matrix3d dart::dynamics::Shape::computeInertia ( double mass ) const

pure virtual

Computes the inertia.

Implemented in dart::dynamics::SphereShape, dart::dynamics::SoftMeshShape, dart::dynamics::PlaneShape, dart::dynamics::MultiSphereConvexHullShape, dart::dynamics::MeshShape, dart::dynamics::LineSegmentShape, dart::dynamics::HeightmapShape< S_ >, dart::dynamics::EllipsoidShape, dart::dynamics::CylinderShape, dart::dynamics::ConeShape, dart::dynamics::CapsuleShape, and dart::dynamics::BoxShape.

◆ computeInertiaFromDensity()

Eigen::Matrix3d dart::dynamics::Shape::computeInertiaFromDensity ( double density ) const

◆ computeInertiaFromMass()

Eigen::Matrix3d dart::dynamics::Shape::computeInertiaFromMass ( double mass ) const

◆ getBoundingBox()

const math::BoundingBox & dart::dynamics::Shape::getBoundingBox ( ) const

Get the bounding box of the shape in its local coordinate frame.

The dimension will be automatically determined by the sub-classes such as BoxShape, EllipsoidShape, CylinderShape, and MeshShape.

◆ getDataVariance()

unsigned int dart::dynamics::Shape::getDataVariance ( ) const

Get the data variance of this shape.

◆ getID()

int dart::dynamics::Shape::getID ( ) const

◆ getShapeType()

Shape::ShapeType dart::dynamics::Shape::getShapeType ( ) const

Deprecated:: Deprecated in 6.1. Please use getType() instead.

◆ getType()

virtual const std::string& dart::dynamics::Shape::getType ( ) const

pure virtual

Returns a string representing the shape type.

See also: is()

Implemented in dart::dynamics::SphereShape, dart::dynamics::SoftMeshShape, dart::dynamics::PlaneShape, dart::dynamics::MultiSphereConvexHullShape, dart::dynamics::MeshShape, dart::dynamics::LineSegmentShape, dart::dynamics::HeightmapShape< S_ >, dart::dynamics::EllipsoidShape, dart::dynamics::CylinderShape, dart::dynamics::ConeShape, dart::dynamics::CapsuleShape, and dart::dynamics::BoxShape.

◆ getVolume()

double dart::dynamics::Shape::getVolume ( ) const

Returns volume of this shape.

The volume will be automatically calculated by the sub-classes such as BoxShape, EllipsoidShape, CylinderShape, and MeshShape.

◆ is()

template<typename ShapeT >

bool dart::dynamics::Shape::is

Get true if the types of this Shape and the template parameter (a shape class) are identical.

This function is a syntactic sugar, which is identical to: (getType() == ShapeType::getStaticType()).

Example code:

auto shape = bodyNode->getShapeNode(0)->getShape();
if (shape->is<BoxShape>())
  std::cout << "The shape type is box!\n";

Notify that the alpha of this shape has updated.

◆ notifyAlphaUpdated()

void dart::dynamics::Shape::notifyAlphaUpdated ( double alpha )

Notify that the alpha of this shape has updated.

Reimplemented in dart::dynamics::MeshShape.

◆ notifyColorUpdate()

void dart::dynamics::Shape::notifyColorUpdate ( const Eigen::Vector4d & color )

◆ notifyColorUpdated()

void dart::dynamics::Shape::notifyColorUpdated ( const Eigen::Vector4d & color )

virtual

Notify that the color (rgba) of this shape has updated.

Reimplemented in dart::dynamics::ArrowShape.

◆ refreshData()

void dart::dynamics::Shape::refreshData ( )

virtual

Instruct this shape to update its data.

◆ removeDataVariance()

void dart::dynamics::Shape::removeDataVariance ( unsigned int _variance )

Remove a type of variance from this shape.

void dart::common::Subject::removeObserver ( Observer * _observer ) const

protectedinherited

Remove an Observer from the list of Observers.

◆ sendDestructionNotification()

void dart::common::Subject::sendDestructionNotification ( ) const

protectedinherited

Send a destruction notification to all Observers.

This will cause all Observers to behave as if this Subject has been permanently deleted, so it should only be called when that behavior is desired.

◆ setDataVariance()

void dart::dynamics::Shape::setDataVariance ( unsigned int _variance )

Set the data variance of this shape.

Use the DataVariance to indicate what kind of shape information might change during run time so that renderers can optimize reliably.

◆ updateBoundingBox()

virtual void dart::dynamics::Shape::updateBoundingBox ( ) const

Updates bounding box.

Implemented in dart::dynamics::SphereShape, dart::dynamics::SoftMeshShape, dart::dynamics::PlaneShape, dart::dynamics::MultiSphereConvexHullShape, dart::dynamics::MeshShape, dart::dynamics::LineSegmentShape, dart::dynamics::HeightmapShape< S_ >, dart::dynamics::EllipsoidShape, dart::dynamics::CylinderShape, dart::dynamics::ConeShape, dart::dynamics::CapsuleShape, and dart::dynamics::BoxShape.
