Detailed Description

Bending constraint. Limits the bending between two neighboring triangles. See [2] for more details.

Constructor & Destructor Documentation

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

Constraint constructor. The target bend is set to the bend between the triangles spanned by four vertices in the parameter positions. The parameters rangeMin and rangeMax can be used to specify a target range for the bend [rangeMin*target_bend,rangeMax*target_bend] The bending constraint applies to two neighboring triangles sharing an edge.

Parameters

idI	are four indices of the vertices of the two triangles ordered as follows: | id2 | | / \ | | id0---id1 | | \ / | | id3 |
idI	are four indices of the vertices of the tetrahedron
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 bend: rangeMin*target_bend.
rangeMax	The factor to determine the maximal bend: rangeMax*target_bend.
