Member Function Documentation

setVertexWeldingThreshold()

void axom::quest::LinearizeCurves::setVertexWeldingThreshold ( double  thresh )

inline

Sets the threshold for welding vertices of adjacent Pieces of curves.

References m_vertexWeldThreshold.

getLinearMeshUniform()

void axom::quest::LinearizeCurves::getLinearMeshUniform	(	CurveArrayView	curves,
		SegmentMesh *	mesh,
		int	segmentsPerKnotSpan
	)		const

Projects high-order NURBS contours onto a linear mesh using segmentsPerPiece linear segments per knot span of the contour.

Knot spans are the sub-intervals within a spline

Parameters

[in]	curves	An array view of curves to linearize.
[in]	mesh	The mesh object that will contain the linearized line segments.
[in]	segmentsPerKnotSpan	The number of segments to make per knot span.

getLinearMeshNonUniform()

void axom::quest::LinearizeCurves::getLinearMeshNonUniform	(	CurveArrayView	curves,
		SegmentMesh *	mesh,
		double	percentError
	)		const

Projects high-order NURBS contours onto a linear mesh using percentError to decide when to stop refinement.

Parameters

[in]	curves	An array view of curves to linearize.
[in]	mesh	The mesh object that will contain the linearized line segments.
[in]	percentError	A percent of error that is acceptable to stop refinement.

getRevolvedVolume()

double axom::quest::LinearizeCurves::getRevolvedVolume	(	CurveArrayView	curves,
		const numerics::Matrix< double > &	transform
	)		const

Compute the revolved volume of the curves using quadrature.

Parameters

[in]	curves	An array view of curves to linearize.
[in]	transform	A 4x4 matrix transform to apply to the shape before computing the revolved volume.

Note

We compute revolved volume on the actual shapes so we can get a real revolved volume computed using the curve functions rather than relying on a linearized curve. The revolved volume is the volume enclosed by the surface of revolution when the shape is revolved about axis of revolution.

Returns

The revolved volume.

revolvedVolume()

double axom::quest::LinearizeCurves::revolvedVolume ( const NURBSCurve &  nurbs, const numerics::Matrix< double > &  transform  ) const

protected

Compute the revolved volume of a single curve using quadrature.

Parameters

[in]	nurbs
[in]	transform	A 4x4 matrix transform to apply to the shape before computing the revolved volume.

Returns

The revolved volume.
