Detailed Description

octree-based spatial search object to quickly locate cells

vtkCellLocator is a spatial search object to quickly locate cells in 3D. vtkCellLocator uses a uniform-level octree subdivision, where each octant (an octant is also referred to as a bucket) carries an indication of whether it is empty or not, and each leaf octant carries a list of the cells inside of it. (An octant is not empty if it has one or more cells inside of it.) Typical operations are intersection with a line to return candidate cells, or intersection with another vtkCellLocator to return candidate cells.

Warning
Many other types of spatial locators have been developed, such as variable depth octrees and kd-trees. These are often more efficient for the operations described here. vtkCellLocator has been designed for subclassing; so these locators can be derived if necessary.

)
overridevirtual

Return intersection point (if any) AND the cell which was intersected by the finite line.

The cell is returned as a cell id and as a generic cell. For other IntersectWithLine signatures, see vtkAbstractCellLocator

Reimplemented from vtkAbstractCellLocator.

void vtkCellLocator::FindClosestPoint ( double  x[3],
double  closestPoint[3],
vtkGenericCell cell,
vtkIdType cellId,
int subId,
double dist2 
)
overridevirtual

Return the closest point and the cell which is closest to the point x.

The closest point is somewhere on a cell, it need not be one of the vertices of the cell. This version takes in a vtkGenericCell to avoid allocating and deallocating the cell. This is much faster than the version which does not take a *cell, especially when this function is called many times in a row such as by a for loop, where the allocation and deallocation can be done only once outside the for loop. If a cell is found, "cell" contains the points and ptIds for the cell "cellId" upon exit.

Reimplemented from vtkAbstractCellLocator.

vtkIdType vtkCellLocator::FindClosestPointWithinRadius ( double  x[3],
double  radius,
double  closestPoint[3],
vtkGenericCell cell,
vtkIdType cellId,
int subId,
double dist2,
int inside 
)
overridevirtual

Return the closest point within a specified radius and the cell which is closest to the point x.

The closest point is somewhere on a cell, it need not be one of the vertices of the cell. This method returns 1 if a point is found within the specified radius. If there are no cells within the specified radius, the method returns 0 and the values of closestPoint, cellId, subId, and dist2 are undefined. This version takes in a vtkGenericCell to avoid allocating and deallocating the cell. This is much faster than the version which does not take a *cell, especially when this function is called many times in a row such as by a for loop, where the allocation and dealloction can be done only once outside the for loop. If a closest point is found, "cell" contains the points and ptIds for the cell "cellId" upon exit. If a closest point is found, inside returns the return value of the EvaluatePosition call to the closest cell; inside(=1) or outside(=0). For other FindClosestPointWithinRadius signatures, see vtkAbstractCellLocator

void vtkCellLocator::FindCellsWithinBounds ( double bbox,

Return a list of unique cell ids inside of a given bounding box.

The user must provide the vtkIdList to populate. This method returns data only after the locator has been built.

Given a finite line defined by the two points (p1,p2), return the list of unique cell ids in the buckets containing the line.

It is possible that an empty cell list is returned. The user must provide the vtkIdList to populate. This method returns data only after the locator has been built.
