Detailed Description

Geometrical edge error metric.

This class is an example implementation of the interface MiEdgeErrorMetric. It is used to check if an edge can be considered linear or not based on the coordinates of its end points coord0 and coord1, the coordinate coordM of the parametric middle point, and a tolerance factor maxError.

This class can be used as an argument to the method MiTessellator::getNewTessellatorGeometry().

◆ getTimeStamp()

virtual size_t MxEdgeErrorMetricGeometry::getTimeStamp ( ) const

inlinevirtual

Returns the current time stamp on this edge error metric.

It changes each time
the method setMaxError() is called.

Implements MiEdgeErrorMetric< MbVec3d >.

◆ isEdgeLinear()

virtual bool MxEdgeErrorMetricGeometry::isEdgeLinear	(	const MbVec3d &	coord0,
		const MbVec3d &	coord1,
		const MbVec3d &	coordM
	)		const

virtual

Check if 3 points are linear based on their coordinates and the tolerance factor maxError.

If the method returns true, the segment defined by [coord0,coordM,coord1] is considered to be linear by the geometrical tessellator (see MiTessellator).

the segment is linear if d < maxError

Parameters

[in]	coord0	coordinate of the first end point of the segment.
[in]	coord1	coordinate of the second end point of the segment.
[in]	coordM	coordinate corresponding the theoretical middle point of the segment.

Returns: true if the distance from the point coordM to the segment [coord0,coord1] < maxError

Implements MiEdgeErrorMetric< MbVec3d >.

◆ setMaxError()

void MxEdgeErrorMetricGeometry::setMaxError ( double maxError )

inline

Set the tolerance factor maxError.

This method also updates the time stamp of the current instance of MxEdgeErrorMetricGeometry.

Parameters

[in] maxError new value of the tolerance factor.
