#include <vtkPointSet.h>
Inheritance diagram for vtkPointSet:
vtkPointSet is an abstract class that specifies the interface for datasets that explicitly use "point" arrays to represent geometry. For example, vtkPolyData and vtkUnstructuredGrid require point arrays to specify point position, while vtkStructuredPoints generates point positions implicitly.

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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkDataSet. Reimplemented in vtkPolyData, vtkStructuredGrid, and vtkUnstructuredGrid. |

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 vtkDataSet. Reimplemented in vtkPolyData, vtkStructuredGrid, and vtkUnstructuredGrid. |
|
Reset to an empty state and free any memory. Reimplemented from vtkDataSet. Reimplemented in vtkPolyData, vtkStructuredGrid, and vtkUnstructuredGrid. |
|
Copy the geometric structure of an input point set object. Implements vtkDataSet. Reimplemented in vtkPolyData, vtkStructuredGrid, and vtkUnstructuredGrid. |

See vtkDataSet for additional information. Implements vtkDataSet. Reimplemented in vtkStructuredGrid. Definition at line 111 of file vtkPointSet.h. References vtkPoints::GetNumberOfPoints(), and Points. Referenced by vtkStructuredGrid::GetNumberOfPoints(). |

Get point coordinates with ptId such that: 0 <= ptId < NumberOfPoints. THIS METHOD IS NOT THREAD SAFE. Implements vtkDataSet. Reimplemented in vtkStructuredGrid. Definition at line 52 of file vtkPointSet.h. Referenced by vtkStructuredGrid::GetPoint(). |
|
Copy point coordinates into user provided array x[3] for specified point id. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED Reimplemented from vtkDataSet. Reimplemented in vtkStructuredGrid. Definition at line 53 of file vtkPointSet.h. |
|
Implements vtkDataSet. |
|
Locate the closest point to the global coordinate x. Return the point id. If point id < 0; then no point found. (This may arise when point is outside of dataset.) THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED Reimplemented from vtkDataSet. Definition at line 55 of file vtkPointSet.h. References vtkDataSet::FindPoint(). |
|
Locate cell based on global coordinate x and tolerance squared. If cell and cellId is non-NULL, then search starts from this cell and looks at immediate neighbors. Returns cellId >= 0 if inside, < 0 otherwise. The parametric coordinates are provided in pcoords[3]. The interpolation weights are returned in weights[]. (The number of weights is equal to the number of points in the found cell). Tolerance is used to control how close the point is to be considered "in" the cell. THIS METHOD IS NOT THREAD SAFE. Implements vtkDataSet. |
|
This is a version of the above method that can be used with multithreaded applications. A vtkGenericCell must be passed in to be used in internal calls that might be made to GetCell() THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED Implements vtkDataSet. |
|
Get MTime which also considers its vtkPoints MTime. Reimplemented from vtkDataSet. |
|
Compute the (X, Y, Z) bounds of the data. Reimplemented from vtkDataSet. Reimplemented in vtkPolyData. |
|
Reclaim any unused memory. Reimplemented from vtkDataSet. Reimplemented in vtkPolyData, and vtkUnstructuredGrid. |
|
Specify point array to define point coordinates. |
|
|
|
Detect reference loop PointSet <-> locator. Reimplemented from vtkDataObject. |
|
Get the net reference count. That is the count minus any self created loops. This is used in the Source/Data registration to properly free the objects. Reimplemented from vtkDataObject. |
|
Return the actual size of the data in kilobytes. This number is valid only after the pipeline has updated. The memory size returned is guaranteed to be greater than or equal to the memory required to represent the data (e.g., extra space in arrays, etc. are not included in the return value). THIS METHOD IS THREAD SAFE. Reimplemented from vtkDataSet. Reimplemented in vtkPolyData, vtkStructuredGrid, and vtkUnstructuredGrid. |
