Detailed Description

abstract class to specify 3D cell interface.

Date:

2001/11/02 16:41:01

Revision:

1.13

vtkCell3D is an abstract class that extends the interfaces for 3D data cells, and implements methods needed to satisfy the vtkCell API. The 3D cells include hexehedra, tetrahedra, wedge, pyramid, and voxel.

Member Function Documentation

virtual const char* vtkCell3D::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkCell. Reimplemented in vtkHexahedron, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

int vtkCell3D::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkCell. Reimplemented in vtkHexahedron, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

virtual int vtkCell3D::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkCell. Reimplemented in vtkHexahedron, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

vtkCell3D* vtkCell3D::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkCell. Reimplemented in vtkHexahedron, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

void vtkCell3D::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkCell.

virtual void vtkCell3D::GetEdgePoints (  int    edgeId, int *&    pts )  [pure virtual]

Get the pair of vertices that define an edge. The method returns the number of vertices, along with an array of vertices. Note that the vertices are 0-offset; that is, they refer to the ids of the cell, not the point ids of the mesh that the cell belongs to. The edgeId must range between 0<=edgeId<this->GetNumberOfEdges(). Reimplemented in vtkHexahedron, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

virtual void vtkCell3D::GetFacePoints (  int    faceId, int *&    pts )  [pure virtual]

Get the list of vertices that define a face. The list is terminated with a negative number. Note that the vertices are 0-offset; that is, they refer to the ids of the cell, not the point ids of the mesh that the cell belongs to. The faceId must range between 0<=faceId<this->GetNumberOfFaces(). Reimplemented in vtkHexahedron, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

virtual void vtkCell3D::Clip (  float    value, vtkDataArray *    cellScalars, vtkPointLocator *    locator, vtkCellArray *    connectivity, vtkPointData *    inPd, vtkPointData *    outPd, vtkCellData *    inCd, vtkIdType    cellId, vtkCellData *    outCd, int    insideOut )  [virtual]

Cut (or clip) the cell based on the input cellScalars and the specified value. The output of the clip operation will be one or more cells of the same topological dimension as the original cell. The flag insideOut controls what part of the cell is considered inside - normally cell points whose scalar value is greater than "value" are considered inside. If insideOut is on, this is reversed. Also, if the output cell data is non-NULL, the cell data from the clipped cell is passed to the generated contouring primitives. (Note: the CopyAllocate() method must be invoked on both the output cell and point data. The cellId refers to the cell from which the cell data is copied.) (Satisfies vtkCell API.) Reimplemented from vtkCell. Reimplemented in vtkTetra.

virtual int vtkCell3D::GetCellDimension (    )  [inline, virtual]

The topological dimension of the cell. (Satisfies vtkCell API.) Reimplemented from vtkCell. Reimplemented in vtkPyramid, vtkVoxel, and vtkWedge. Definition at line 101 of file vtkCell3D.h.
