Detailed Description

This subclass of Contact is used when one or both of the ContactGeometry objects is a TriangleMesh.

It stores a list of every face on each object that is partly or completely inside the other one.

Constructor & Destructor Documentation

◆ TriangleMeshContact()

SimTK::TriangleMeshContact::TriangleMeshContact	(	ContactSurfaceIndex	surf1,
		ContactSurfaceIndex	surf2,
		const Transform &	X_S1S2,
		const std::set< int > &	faces1,
		const std::set< int > &	faces2
	)

Create a TriangleMeshContact object.

Parameters

surf1	the index of the first surface involved in the contact, specified by its index within its contact set
surf2	the index of the second surface involved in the contact, specified by its index within its contact set
X_S1S2	the transform giving surf2's frame measured and expressed in surf1's frame
faces1	the indices of all faces in the first surface which are inside the second one
faces2	the indices of all faces in the second surface which are inside the first one

Member Function Documentation

◆ getSurface1Faces()

const std::set<int>& SimTK::TriangleMeshContact::getSurface1Faces ( ) const

Get the indices of all faces of surface1 that are partly or completely inside surface2.

If surface1 is not a TriangleMesh, this will return an empty set.

◆ getSurface2Faces()

const std::set<int>& SimTK::TriangleMeshContact::getSurface2Faces ( ) const

Get the indices of all faces of surface2 that are partly or completely inside surface1.

If surface2 is not a TriangleMesh, this will return an empty set.

◆ isInstance()

static bool SimTK::TriangleMeshContact::isInstance ( const Contact & contact )

static

Determine whether a Contact object is a TriangleMeshContact.

◆ getAs()

static const TriangleMeshContact& SimTK::TriangleMeshContact::getAs ( const Contact & contact )

inlinestatic

Recast a triangle mesh given as a generic Contact object to a const reference to a concrete TriangleMeshContact object.

◆ updAs()

static TriangleMeshContact& SimTK::TriangleMeshContact::updAs ( Contact & contact )

inlinestatic

Recast a triangle mesh given as a generic Contact object to a writable reference to a concrete TriangleMeshContact object.

◆ classTypeId()

static ContactTypeId SimTK::TriangleMeshContact::classTypeId ( )

static

Obtain the unique small-integer id for the TriangleMeshContact class.
