Detailed Description

Edge strain constraint. Constrains the distance between two points to a range. See [2] for more details.

Constructor & Destructor Documentation

SHAPEOP_INLINE ShapeOp::EdgeStrainConstraint::EdgeStrainConstraint	(	const std::vector< int > &	idI,
		Scalar	weight,
		const Matrix3X &	positions,
		Scalar	rangeMin = 1.0,
		Scalar	rangeMax = 1.0
	)

Constraint constructor. The target length is set to the distance of the two vertices in the parameter positions. The parameters rangeMin and rangeMax can be used to specify a target range for the distance (equivalent to edge length) [rangeMin*distance,rangeMax*distance].

Parameters

idI	are two indices of the vertices of the edge.
weight	The weight of the constraint to be added relative to the other constraints.
positions	The positions of all the n vertices stacked in a 3 by n matrix.
rangeMin	The factor to determine the minimal distance from the target length: rangeMin*distance
rangeMax	The factor to determine the maximal distance from the target length: rangeMax*distance
