Member Function Documentation

◆ addFace()

size_t FFaBody::addFace	(	int	i1,
		int	i2,
		int	i3,
		int	i4 = `-1`
	)

Adds a face to the body definition.

◆ addVertex()

size_t FFaBody::addVertex	(	const FaVec3 &	pos,
		double	tol = `-1.0`
	)

Adds a vertex to the body definition.

◆ computeBoundingBox()

bool FFaBody::computeBoundingBox	(	FaVec3 &	minX,
		FaVec3 &	maxX
	)		const

Computes the bounding box of the body.

◆ computeIncArea()

bool FFaBody::computeIncArea	(	double &	dAs,
		FaVec3 &	C0s,
		const FaVec3 &	normal,
		const FaMat34 &	cs
	)

Computes the increment in the intersection area and the associated centroid. It is assumed that computeVolumeBelow already has been invoked before calling this method such that the current face intersections are available.

◆ computeTotalVolume()

bool FFaBody::computeTotalVolume	(	double &	Vb,
		FaVec3 &	C0b,
		FFaTensor3 *	Ib = `NULL`
	)		const

Computes the total volume, volume centroid, and optionally the volume inertia.

◆ computeVolumeBelow()

bool FFaBody::computeVolumeBelow	(	double &	Vb,
		double &	As,
		FaVec3 &	C0b,
		FaVec3 &	C0s,
		const FaVec3 &	normal,
		double	z0,
		double	zeroTol = `1.0e-16`
	)

Computes the volume and centroid of the portion of the body that is below the plane defined by normal and z0. The area of the intersection surface and the associated centroid is also computed, if the body is intersected.

◆ getFaceVtx()

int FFaBody::getFaceVtx	(	size_t	idx,
		int	i
	)		const

	)

static

This method administers the input of a body definition from a file. The body may either be defined on FT's internal CAD format, or on the external VRML or STL formats.

◆ saveIntersection()

bool FFaBody::saveIntersection ( const FaMat34 & cs )

Saves the loop of vertices defining the current intersection surface. The vertex coordinates of the loop are transformed to global coordinates using cs to facilitate comparison with a previous configuration.

◆ writeCAD()

bool FFaBody::writeCAD	(	const std::string &	fileName,
		const FaMat34 &	partCS
	)		const

This method writes out the body definition on FT's internal CAD format.
