Class CurvatureSampling

java.lang.Object

cz.fidentis.analyst.engines.sampling.impl.PointSamplingVisitorImpl

cz.fidentis.analyst.engines.sampling.impl.CurvatureSampling

All Implemented Interfaces:

MeshVisitor, PointSamplingVisitor

public class CurvatureSampling
extends PointSamplingVisitorImpl

A relevance-based point sampling using the highest curvature (see this paper). If curvature is not set in inspected facets, then it is computed and set automatically. This visitor is tread-safe.

Constructor Details

CurvatureSampling

public CurvatureSampling(CurvatureSampling.CurvatureAlg cAlg,
 int max)

Constructor.

Parameters:

cAlg - Curvature strategy to be used for the selection of significant points.

max - Maximal number of significant points

Throws:

IllegalArgumentException - if the curbatureVisitor is missing

Method Details

visitMeshFacet

public void visitMeshFacet(MeshFacet facet)

Description copied from interface: MeshVisitor

The inspection method to be implemented by specific visitors.

Specified by:

visitMeshFacet in interface MeshVisitor

Specified by:

visitMeshFacet in interface PointSamplingVisitor

Specified by:

visitMeshFacet in class PointSamplingVisitorImpl

Parameters:

facet - Mesh facet to be visited.

getSamples

public List<MeshPoint> getSamples()

Description copied from interface: PointSamplingVisitor

Returns a list of vertices reduced according to the strategy. The returned mesh points are backed by original points.

Specified by:

getSamples in interface PointSamplingVisitor

Specified by:

getSamples in class PointSamplingVisitorImpl

Returns:

selected vertices of inspected meshes

isBackedByOrigMesh

public boolean isBackedByOrigMesh()

Description copied from interface: PointSamplingVisitor

If true, then the returned points samples are points from the original mesh. Therefore, the transformation of the original mesh also transform these samples. If false, then new points are returned that are independent on the original mesh.

Specified by:

isBackedByOrigMesh in interface PointSamplingVisitor

Specified by:

isBackedByOrigMesh in class PointSamplingVisitorImpl

Returns:

true if the point samples include points of the original mesh

getCurvatureAlg

public CurvatureSampling.CurvatureAlg getCurvatureAlg()

toString

public String toString()

Overrides:

toString in class PointSamplingVisitorImpl
