Detailed Description

Angle range constraint. Constrains the angle between the two lines formed by three points to a range. See [3] for more details.

Constructor & Destructor Documentation

SHAPEOP_INLINE ShapeOp::AngleConstraint::AngleConstraint	(	const std::vector< int > &	idI,
		Scalar	weight,
		const Matrix3X &	positions,
		Scalar	minAngle = `0.0`,
		Scalar	maxAngle = `M_PI`
	)

Constraint constructor.

Parameters

idI	are three indices of the vertices [v0,v1,v2]. The constrained angle is the one spanned between v1-v0 and v2-v0: \| id0 \| \| / \| \| \| / \| \| \| id1 id2 \|
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.
minAngle	The minimum angle (in radian, between 0 and PI).
maxAngle	The maximum angle (in radian, between 0 and PI).
