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().

Get the ids of the two adjacent faces to edge of id edgeId.
The output face ids are sorted from id of lowest rank to highest. Note that the faces are 0-offset; that is, they refer to the ids of the cells, not the face ids of the mesh that the cell belongs to. The edgeId must range between 0<=edgeId<this->GetNumberOfEdges().

Get the ids of the adjacent faces to face of id faceId.
The order of faces is consistent. They are always ordered in counter clockwise w.r.t. normal orientation. The first id faces[0] corresponds to the face sharing point of id pts[0] where pts is obtained from this->GetFacePoints(faceId, pts), being the "most counter clockwise" oriented w.r.t. face faceId. Note that the faces are 0-offset; that is, they refer to the ids of the cell, not the face ids of the mesh that the cell belongs to. The faceId must be between 0<=faceId<this->GetNumberOfFaces();
Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkWedge, and vtkVoxel.

pure virtual |
Get the ids of the incident edges to point of id pointId.
Edges are sorted in counter clockwise order w.r.t. bisectrix pointing outside the cell at point of id pointId. The first edge corresponds to the edge containing point of id pts[0], where pts is obtained from this->GetPointToOnRingVertices(pointId, pts). Note that the edges are 0-offset; that is, they refer to the ids of the cell, not the edge ids of the mesh that the cell belongs to. The edgeId must be between 0<=edgeId<this->GetNumberOfEdges();

Note that the faces are 0-offset; that is, they refer to the ids of the cell, not the face ids of the mesh that the cell belongs to. The pointId must be between 0<=pointId<this->GetNumberOfPoints().

Points are sorted in counter clockwise order w.r.t. bisectrix pointing outside the cell at point of id pointId.

Note that the points 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 pointId must be between 0<pointId<this->GetNumberOfPoints().

Generate contouring primitives.
The scalar list cellScalars are scalar values at each cell point. The point locator is essentially a points list that merges points as they are inserted (i.e., prevents duplicates). Contouring primitives can be vertices, lines, or polygons. It is possible to interpolate point data along the edge by providing input and output point data - if outPd is nullptr, then no interpolation is performed. Also, if the output cell data is non-nullptr, the cell data from the contoured 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.)
Implements vtkCell.
Reimplemented in vtkConvexPointSet, vtkHexahedron, vtkPyramid, vtkTetra, vtkVoxel, vtkWedge, and vtkPolyhedron.
|
overridevirtual |
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-nullptr, 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.)

Inflates the cell.
Each face is displaced following its normal by a distance of value dist
. If dist is negative, then the cell shrinks. The resulting cell edges / faces are colinear / coplanar to their previous self.
Degenerate parts of the 3D cell are unchanged. This happens a points to which incident faces are homogeneous to a plane, to a line, or to a point.
