public interface LODCriterion

Interface for LOD criteria, i.e. functions that determine whether Arcs in the DAG have to be "applied" (the arcs correspond to mesh refinements) during selective refinement / spatial selection.

Field Summary

static LODCriterion	COARSEST Static instance of a Coarsest criterion, use this to extract the coarsest LOD contained in a MultiresolutionMesh.
static LODCriterion	FINEST Static instance of a Finest criterion, use this to extract the finest LOD contained in a MultiresolutionMesh.

Method Summary

boolean

needsRefinement(Arc arc) Checks whether the given Arc is necessary in order to satisfy this LOD criterion.

Field Detail

COARSEST

static final LODCriterion COARSEST

Static instance of a Coarsest criterion, use this to extract the coarsest LOD contained in a MultiresolutionMesh.

FINEST

static final LODCriterion FINEST

Static instance of a Finest criterion, use this to extract the finest LOD contained in a MultiresolutionMesh.

Method Detail

needsRefinement

boolean needsRefinement(Arc arc)

Checks whether the given Arc is necessary in order to satisfy this LOD criterion.

Parameters:

arc - arc to be checked

Returns:

true, if the arc is necessary, false otherwise
