Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject. |
|
|
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. |
|
|
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. |

|
|
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. |
|
|
Make a new vtkVertex object with the same information as this object. Reimplemented from vtkCell. |
|
|
See the vtkCell API for descriptions of these methods. Reimplemented from vtkCell. Definition at line 67 of file vtkVertex.h. |
|
|
Return the topological dimensional of the cell (0,1,2, or 3). Reimplemented from vtkCell. Definition at line 68 of file vtkVertex.h. |
|
|
Return the number of edges in the cell. Reimplemented from vtkCell. Definition at line 69 of file vtkVertex.h. |
|
|
Return the number of faces in the cell. Reimplemented from vtkCell. Definition at line 70 of file vtkVertex.h. |
|
|
Return the edge cell from the edgeId of the cell. Reimplemented from vtkCell. Definition at line 71 of file vtkVertex.h. |
|
|
Return the face cell from the faceId of the cell. Reimplemented from vtkCell. Definition at line 72 of file vtkVertex.h. |

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.) Reimplemented from vtkCell. |

|
Given a point x[3] return inside(=1) or outside(=0) cell; evaluate parametric coordinates, sub-cell id (!=0 only if cell is composite), distance squared of point x[3] to cell (in particular, the sub-cell indicated), closest point on cell to x[3] (unless closestPoint is null, in which case, the closest point and dist2 are not found), and interpolation weights in cell. (The number of weights is equal to the number of points defining the cell). Note: on rare occasions a -1 is returned from the method. This means that numerical error has occurred and all data returned from this method should be ignored. Also, inside/outside is determine parametrically. That is, a point is inside if it satisfies parametric limits. This can cause problems for cells of topological dimension 2 or less, since a point in 3D can project onto the cell within parametric limits but be "far" from the cell. Thus the value dist2 may be checked to determine true in/out. Reimplemented from vtkCell. |

|
Determine global coordinate (x[3]) from subId and parametric coordinates. Also returns interpolation weights. (The number of weights is equal to the number of points in the cell.) Reimplemented from vtkCell. |
|
||||||||||||||||
|
Given parametric coordinates of a point, return the closest cell boundary, and whether the point is inside or outside of the cell. The cell boundary is defined by a list of points (pts) that specify a vertex (1D cell). If the return value of the method is != 0, then the point is inside the cell. Reimplemented from vtkCell. |

|
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). Reimplemented from vtkCell. |
|
||||||||||||||||||||||||||||||||
|
Intersect with a ray. Return parametric coordinates (both line and cell) and global intersection coordinates, given ray definition and tolerance. The method returns non-zero value if intersection occurs. Reimplemented from vtkCell. |
|
||||||||||||||||
|
Triangulate the vertex. This method fills pts and ptIds with information from the only point in the vertex. Reimplemented from vtkCell. |
|
||||||||||||||||||||||||
|
Get the derivative of the vertex. Returns (0.0, 0.0, 0.0) for all dimensions. Reimplemented from vtkCell. |
