Member Function Documentation

◆ AddCamera()

void chrono::ChObj::AddCamera ( std::shared_ptr< ChCamera > camera )

Attach a camera to this object.

Multiple cameras can be attached to the same object.

◆ AddVisualModel()

void chrono::ChObj::AddVisualModel ( std::shared_ptr< ChVisualModel > model )

Add an (optional) visualization model.

Not that an instance of the given visual model is associated with this object, thus allowing sharing the same model among multiple objects.

◆ AddVisualShape()

void chrono::ChObj::AddVisualShape	(	std::shared_ptr< ChVisualShape >	shape,
		const ChFrame<> &	frame = `ChFrame<>()`
	)

Add the specified visual shape to the visualization model.

If this object does not have a visual model, one is created.

◆ AddVisualShapeFEA()

void chrono::ChObj::AddVisualShapeFEA ( std::shared_ptr< ChVisualShapeFEA > shapeFEA )

Add the specified FEA visualization object to the visualization model.

If this object does not have a visual model, one is created.

◆ GetIdentifier()

int chrono::ChObj::GetIdentifier ( ) const

inline

Get the unique integer identifier of this object.

Object identifiers are generated automatically in incremental order based on the order in which objects are created. These identifiers are transient and as such are not serialized. However, user code can cache the identifier of any Chrono object and use it later (e.g., to search the item in a ChAssembly).

◆ GetNumVisualModelClones()

virtual unsigned int chrono::ChObj::GetNumVisualModelClones ( ) const

inlinevirtual

Return the number of clones of the visual model associated with this object.

If the visual model is cloned (for example for an object modeling a particle system), this function should return the total number of copies of the visual model, including the "original". The current coordinate frame of a given clone can be obtained by calling GetVisualModelFrame() with the corresponding clone identifier.

Reimplemented in chrono::ChIndexedParticles.

◆ GetVisualModel()

std::shared_ptr< ChVisualModel > chrono::ChObj::GetVisualModel ( ) const

Access the visualization model (if any).

Note that this model may be shared with other objects that may instance it. Returns nullptr if no visual model is present.

◆ GetVisualModelFrame()

virtual ChFrame chrono::ChObj::GetVisualModelFrame ( unsigned int nclone = 0 ) const

inlinevirtual

Get the reference frame (expressed in and relative to the absolute frame) of the visual model.

If the visual model is cloned (for example for an object modeling a particle system), this function returns the coordinate system of the specified clone.

Reimplemented in chrono::ChBody, chrono::ChLinkRSDA, chrono::ChLinkMarkers, chrono::ChIndexedParticles, chrono::ChLinkBase, and chrono::ChLinkMateGeneric.

◆ GetVisualShape()

std::shared_ptr< ChVisualShape > chrono::ChObj::GetVisualShape ( unsigned int i ) const

Access the specified visualization shape in the visualization model (if any).

Note that no range check is performed.

◆ GetVisualShapeFEA()

std::shared_ptr< ChVisualShapeFEA > chrono::ChObj::GetVisualShapeFEA ( unsigned int i ) const

Access the specified FEA visualization object in the visualization model (if any).

Note that no range check is performed.

◆ SetTag()

void chrono::ChObj::SetTag ( int tag )

inline

Set an object integer tag (default: -1).

Unlike the object identifier, this tag is completely under user control and not used anywhere else in Chrono. Tags are serialized and de-serialized.

◆ Update()

void chrono::ChObj::Update	(	double	time,
		bool	update_assets
	)

virtual

Perform any updates necessary at the current phase during the solution process.

This function is called at least once per step to update auxiliary data, internal states, etc. The default implementation updates the item's time stamp and its visualization assets (if any are defined anf only if requested).

Reimplemented in chrono::ChLinkMateRackPinion, chrono::modal::ChModalAssembly, chrono::ChParticleCloud, chrono::ChBody, chrono::fea::ChLinkNodeFaceRot, chrono::ChLinkMatePlanar, chrono::fea::ChLinkNodeFrameGeneric, chrono::ChExternalFmu, chrono::ChAssembly, chrono::ChExternalDynamicsDAE, chrono::ChLoadNodeXYZNodeXYZ, chrono::ChLinkMateGeneric, chrono::ChMarker, chrono::ChLinkLock, chrono::ChShaft, chrono::ChLoadNodeXYZForceAbs, chrono::ChForce, chrono::ChHydraulicActuatorBase, chrono::ChLinkMarkers, chrono::fea::ChLinkNodeFace, chrono::ChLinkRevoluteTranslational, chrono::fea::ChLoadNodeXYZRotForceAbs, chrono::ChLinkRevoluteSpherical, chrono::ChLoadNodeXYZForce, chrono::fea::ChLinkBeamIGAFrame, chrono::fea::ChLinkNodeFrame, chrono::ChLoadBase, chrono::ChShaftsTorqueConverter, chrono::ChPhysicsItem, chrono::fea::ChLinkNodeSlopeFrame, chrono::ChExternalDynamicsODE, chrono::ChLinkMotorRotation, chrono::fea::ChLinkNodeNode, chrono::ChLinkMotorLinear, chrono::ChLink, chrono::fea::ChLoadNodeXYZRot, chrono::ChBodyAuxRef, chrono::ChShaftsTorque, chrono::ChLinkMotor, chrono::ChLoadContainer, chrono::peridynamics::ChPeridynamics, chrono::ChLinkMateOrthogonal, chrono::ChLinkMateDistanceZ, chrono::ChContactContainerSMC, chrono::ChContactContainerNSC, and chrono::fea::ChMesh.
