Member Function Documentation

◆ clone()

ContactMesh* OpenSim::ContactMesh::clone ( ) const

inlineoverridevirtual

Create a new heap-allocated copy of the concrete object to which this Object refers.

It is up to the caller to delete the returned object when no longer needed. Every concrete object deriving from Object implements this pure virtual method automatically, via the declaration macro it invokes (e.g., OpenSim_DECLARE_CONCRETE_OBJECT()). Note that the concrete class overrides modify the return type to be a pointer to the concrete object; that still overrides the base class method because the return type is covariant with (that is, derives from) Object.

Implements OpenSim::ContactGeometry.

◆ createSimTKContactGeometry()

SimTK::ContactGeometry OpenSim::ContactMesh::createSimTKContactGeometry ( ) const

overridevirtual

Create a new SimTK::ContactGeometry based on this object.

Implements OpenSim::ContactGeometry.

◆ generateDecorations()

void OpenSim::ContactMesh::generateDecorations	(	bool	fixed,
		const ModelDisplayHints &	hints,
		const SimTK::State &	state,
		SimTK::Array_< SimTK::DecorativeGeometry > &	appendToThis
	)		const

overridevirtual

Optional method for generating arbitrary display geometry that reflects this Component at the specified state.

This will be called once to obtain ground- and body-fixed geometry (with fixed=true), and then once per frame (with fixed=false) to generate on-the-fly geometry such as rubber band lines, force arrows, labels, or debugging aids.

Please note that there is a precondition that the state passed in to generateDecorations be realized to Stage::Position. If your component can visualize quantities realized at Velocity, Dynamics or Acceleration stages, then you must check that the stage has been realized before using/requesting stage dependent values. It is forbidden to realize the model to a higher stage within generateDecorations, because this can trigger costly side- effects such as evaluating all model forces even when performing a purely kinematic study.

If you override this method, be sure to invoke the base class method first, using code like this:

void MyComponent::generateDecorations
   (bool                                        fixed,
    const ModelDisplayHints&                    hints,
    const SimTK::State&                         state,
    SimTK::Array_<SimTK::DecorativeGeometry>&   appendToThis) const
{
    // invoke parent class method
    Super::generateDecorations(fixed,hints,state,appendToThis);
    // ... your code goes here
    // can render velocity dependent quanities if stage is Velocity or higher
    if(state.getSystemStage() >= Stage::Velocity) {
        // draw velocity vector for model COM
    }
    // can render computed forces if stage is Dynamics or higher
    if(state.getSystemStage() >= Stage::Dynamics) {
        // change the length of a force arrow based on the force in N
    }
}

Parameters

[in]	fixed	If `true`, generate only geometry that is fixed to a PhysicalFrame, configuration, and velocity. Otherwise generate only such dependent geometry.
[in]	hints	See documentation for ModelDisplayHints; you may want to alter the geometry you generate depending on what you find there. For example, you can determine whether the user wants to see debug geometry.
[in]	state	The State for which geometry should be produced. See below for more information.
[in,out]	appendToThis	Array to which generated geometry should be appended via the `push_back()` method.

When called with fixed=true only modeling options and parameters (Instance variables) should affect geometry; time, position, and velocity should not. In that case OpenSim will already have realized the state through Instance stage. When called with fixed=false, you may consult any relevant value in state. However, to avoid unnecessary computation, OpenSim guarantees only that state will have been realized through Position stage; if you need anything higher than that (reaction forces, for example) you should make sure the state is realized through Acceleration stage.

Reimplemented from OpenSim::Component.

◆ get_filename()

const std::string& OpenSim::ContactMesh::get_filename ( ) const

inline

Get the value of the filename property.

◆ getClassName()

static const std::string& OpenSim::ContactMesh::getClassName ( )

inlinestatic

This returns "ContactMesh".

See getConcreteClassName() if you want the class name of the underlying concrete object instead.

◆ getConcreteClassName()

const std::string& OpenSim::ContactMesh::getConcreteClassName ( ) const

inlineoverridevirtual

Returns the class name of the concrete Object-derived class of the actual object referenced by this Object, as a string.

This is the string that is used as the tag for this concrete object in an XML file. Every concrete class derived from Object automatically overrides this method via the declaration macro it uses. See getClassName() to get the class name of the referencing (possibly abstract) class rather than the concrete object.

See also: getClassName()

Implements OpenSim::ContactGeometry.

◆ getFilename()

const std::string& OpenSim::ContactMesh::getFilename ( ) const

Get the name of the file the mesh is loaded from.

◆ safeDownCast()

static ContactMesh* OpenSim::ContactMesh::safeDownCast ( OpenSim::Object * obj )

inlinestatic

For use in MATLAB and Python to access the concrete class.

Example: cObj = ContactMesh.safeDownCast(obj). This is equivalent to dynamic_cast<ContactMesh*>(obj) in C++.

◆ set_filename()

void OpenSim::ContactMesh::set_filename ( const std::string & value )

inline

Set the value of the filename property.

◆ setFilename()

void OpenSim::ContactMesh::setFilename ( const std::string & filename )

Set the name of the file to load the mesh from.

◆ upd_filename()

std::string& OpenSim::ContactMesh::upd_filename ( )

inline

Get a writable reference to the filename property.

◆ filename

std::string OpenSim::ContactMesh::filename

"Path to mesh geometry file (supports .obj, .stl, .vtp). " "Mesh should be closed and water-tight."

This property appears in XML files under the tag <filename>. This property was generated with the OpenSim_DECLARE_PROPERTY macro; see Property to learn about the property system.
