All Implemented Interfaces:

Direct Known Subclasses:

public abstract class MiSphereSliceExtractIjk
extends java.lang.Object
implements MiExtractorIjk

Sphere slice extractor for structured volume meshes.

A sphere slice is the intersection of a given sphere with the mesh volume. The extracted sphere slice is an unstructured surface mesh.

Additional data sets can be mapped onto this extracted surface by calling the extractScalarSet(MiScalardSetIjk) or extractVec3Set(MiVec3dSetIjk) methods.

The following sample code shows how to extract a sphere slice from a mesh:

 
 {
   MiSphereSliceExtractIjk sphereSliceExtract = MiSphereSliceExtractIjk.getNewInstance(mesh);
   MeXSurfaceMeshUnstructured sphereSlice = sphereSliceExtract.extractSlice(center,radius, null);
 }

Method Detail

getNewInstance

public static <T extends MiTopologyIjk,G extends MiGeometryHexahedronIjk> MiSphereSliceExtractIjk getNewInstance(MiVolumeMeshVertexHexahedronIjk<T,G> mesh)

Create an instance of sphere slice extractor for a non indexed hexahedron volume mesh IJK.

Parameters:

mesh - the input mesh

Returns:

a sphere slice extractor for a non indexed hexahedron volume mesh IJK.

extractSlice

public abstract MeXSurfaceMeshUnstructured<MeXSurfaceCell,MeXSurfaceTopologyExplicitI<MeXSurfaceCell>,MeXGeometryI> extractSlice(SbVec3d center,
                                                                                                                                             double radius,
                                                                                                                                             MiCellFilterIjk filter)

Builds the topology and geometry of a sphere slice intersecting the volume mesh.

Parameters:

center - the position of the center of the sphere

radius - the radius of the sphere

filter - the cell filter

Returns:

an unstructured surface mesh representing the sphere slice

extractScalarSet

public abstract MeXScalardSetI extractScalarSet(MiScalardSetIjk scalarSet)

Computes a PER_CELL scalar set on the extracted sphere slice.

Note: The argument i,j,k of the method MiScalardSetIjk.get(int, int, int) refers to the cell (i,j,k). Thus the binding of the input set must be PER_CELL. An UnsupportedOperationException is thrown otherwise.

Parameters:

scalarSet - the input scalar set defined on the volume mesh

Returns:

the output scalar set defined on the resulting sphere slice mesh

extractVec3Set

public abstract MeXVec3dSetI extractVec3Set(MiVec3dSetIjk vectorSet)

Computes a vector set on the extracted sphere slice.

Note: The argument i,j,k of the method MiVec3dSetIjk.get(int, int, int) refers to the cell (i,j,k). Thus the binding of the input set must be PER_CELL. An UnsupportedOperationException is thrown otherwise.

Parameters:

vectorSet - the input vector set defined on the volume mesh

Returns:

the output vector set defined on the resulting sphere slice mesh

getExtract

public abstract MeXSurfaceMeshUnstructured<MeXSurfaceCell,MeXSurfaceTopologyExplicitI<MeXSurfaceCell>,MeXGeometryI> getExtract()

Returns the result of the extraction as a mesh.

Returns:

result of the extraction as a mesh
