Detailed Description

template<typename _T>
class MiEdgeErrorMetric< _T >

Edge error metric interface used by the tessellator.

This class is used to check if an edge can be considered as linear or not. The isEdgeLinear method is called by the tessellator in order to estimate the quality of an edge tessellation and thus the quality of the mesh tessellation.

Note:

In order to have a "crack free" tesselation (tessellation without any small gaps along the edges) the method isEdgeLinear() must be symmetric: calling isEdgeLinear(O,P,Q) must return the same result as calling isEdgeLinear(P,O,Q).

See MxEdgeErrorMetricGeometry for an example of implementation of this interface. It defines a geometrical criterion by using only the coordinates of an edge to check if it could be seen as linear or not.

Member Function Documentation

template<typename _T>

virtual size_t MiEdgeErrorMetric< _T >::getTimeStamp

(

)

const [pure virtual]

Returns a time stamp on this edge error metric.

Whenever any parameter used by the application method isEdgeLinear() changes, the time stamp must increase.

Implemented in MxEdgeErrorMetricGeometry.

template<typename _T>

virtual bool MiEdgeErrorMetric< _T >::isEdgeLinear	(	const _T &	v0,
		const _T &	v1,
		const _T &	vM
	)			const [pure virtual]

Checks if an edge can be seen as linear or not according to its coordinates or its values.

Given 2 values v0,v1 at the end points of the edge, and one value vM at the theoretical middle point of the edge, the method returns true if the edge can be seen as linear.

Parameters:

[in]	v0	value at the first end point of the edge.
[in]	v1	value at the second end point of the edge.
[in]	vM	value at the theoretical middle point of the edge.

Returns:

true if the edge can be seen as linear.

Implemented in MxEdgeErrorMetricGeometry.
