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. |

Copy the geometric and topological structure of an input image data object. Implements vtkDataSet. |

Determine the number of points composing the dataset. THIS METHOD IS THREAD SAFE Implements vtkDataSet. Definition at line 275 of file vtkUniformGrid.h. References GetDimensions(). |
|
Get point coordinates with ptId such that: 0 <= ptId < NumberOfPoints. THIS METHOD IS NOT THREAD SAFE. Implements vtkDataSet. Referenced by 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. Definition at line 267 of file vtkUniformGrid.h. References GetPoint(). |
|
Get cell with cellId such that: 0 <= cellId < NumberOfCells. THIS METHOD IS NOT THREAD SAFE. Implements vtkDataSet. |
|
Get cell with cellId such that: 0 <= cellId < NumberOfCells. This is a thread-safe alternative to the previous GetCell() method. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED Implements vtkDataSet. |
|
Get the bounds of the cell with cellId such that: 0 <= cellId < NumberOfCells. A subclass may be able to determine the bounds of cell without using an expensive GetCell() method. A default implementation is provided that actually uses a GetCell() call. This is to ensure the method is available to all datasets. Subclasses should override this method to provide an efficient implementation. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED Reimplemented from 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 75 of file vtkUniformGrid.h. References vtkDataSet::FindPoint(). |
|
Implements vtkDataSet. |
|
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. |
|
Locate the cell that contains a point and return the cell. Also returns the subcell id, parametric coordinates and weights for subsequent interpolation. This method combines the derived class methods int FindCell and vtkCell *GetCell. Derived classes may provide a more efficient implementation. See for example vtkStructuredPoints. THIS METHOD IS NOT THREAD SAFE. Reimplemented from vtkDataSet. |

Convenience method returns largest cell size in dataset. This is generally used to allocate memory for supporting data structures. THIS METHOD IS THREAD SAFE Implements vtkDataSet. Definition at line 93 of file vtkUniformGrid.h. |
|
Convenience method to get the range of the scalar data (if there is any scalar data). Returns the (min/max) range of combined point and cell data. If there are no point or cell scalars the method will return (0,1). Note: Update needs to be called to create the scalars.

|
Call superclass method to avoid hiding Since this data type does not use 3D extents, this set method is useless but necessary since vtkDataSetToDataSetFilter does not know what type of data it is working on. Reimplemented from vtkDataObject. Definition at line 111 of file vtkUniformGrid.h. |

|
|
Convenience function computes the structured coordinates for a point x[3]. The voxel is specified by the array ijk[3], and the parametric coordinates in the cell are specified with pcoords[3]. The function returns a 0 if the point x is outside of the volume, and a 1 if inside the volume. |
|
Return the dimensionality of the data. Definition at line 281 of file vtkUniformGrid.h. References vtkStructuredData::GetDataDimension(). |

Description: Different ways to set the extent of the data array. The extent should be set before the "Scalars" are set or allocated. The Extent is stored in the order (X, Y, Z). |
|
|

|
|
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. |
|
Set the spacing (width,height,length) of the cubical cells that compose the data set. |
|
|
|
|
|
|
|
|
|
Set the origin of the data. The origin plus spacing determine the position in space of the points. |
