Detailed Description

Objects that compute error during cell tessellation.

Objects of that class answer the following question during the cell subdivision: "does the edge need to be subdivided?" through RequiresEdgeSubdivision(). The answer depends on the criterium actually used in the subclass of this abstract class: a geometric-based error metric (variation of edge from a straight line), an attribute-based error metric (variation of the active attribute/component value from a linear ramp) , a view-depend error metric, ... Cell subdivision is performed in the context of the adaptor framework: higher-order, or complex cells, are automatically tessellated into simplices so that they can be processed with conventional visualization algorithms.

virtual int vtkGenericSubdivisionErrorMetric::RequiresEdgeSubdivision	(	double *	leftPoint,
		double *	midPoint,
		double *	rightPoint,
		double	alpha
	)

pure virtual

Does the edge need to be subdivided according to the implemented computation? The edge is defined by its `leftPoint' and its `rightPoint'. `leftPoint', `midPoint' and `rightPoint' have to be initialized before calling RequiresEdgeSubdivision(). Their format is global coordinates, parametric coordinates and point centered attributes: xyx rst abc de... `alpha' is the normalized abscissa of the midpoint along the edge. (close to 0 means close to the left point, close to 1 means close to the right point)

Precondition: leftPoint_exists: leftPoint!=0; midPoint_exists: midPoint!=0; rightPoint_exists: rightPoint!=0; clamped_alpha: alpha>0 && alpha<1; valid_size: sizeof(leftPoint)=sizeof(midPoint)=sizeof(rightPoint) =GetAttributeCollection()->GetNumberOfPointCenteredComponents()+6

Implemented in vtkAttributesErrorMetric, vtkViewDependentErrorMetric, vtkGeometricErrorMetric, and vtkSmoothErrorMetric.

virtual double vtkGenericSubdivisionErrorMetric::GetError	(	double *	leftPoint,
		double *	midPoint,
		double *	rightPoint,
		double	alpha
	)

pure virtual

Return the error at the mid-point. The type of error depends on the state of the concrete error metric. For instance, it can return an absolute or relative error metric. See RequiresEdgeSubdivision() for a description of the arguments.

Precondition: leftPoint_exists: leftPoint!=0; midPoint_exists: midPoint!=0; rightPoint_exists: rightPoint!=0; clamped_alpha: alpha>0 && alpha<1; valid_size: sizeof(leftPoint)=sizeof(midPoint)=sizeof(rightPoint) =GetAttributeCollection()->GetNumberOfPointCenteredComponents()+6

Postcondition: positive_result: result>=0

Implemented in vtkAttributesErrorMetric, vtkViewDependentErrorMetric, vtkGeometricErrorMetric, and vtkSmoothErrorMetric.
