an abstract base class for locators which find cells
virtual vtkIdType FindCell(double x[3])
Returns the Id of the cell containing the point, returns -1 if no cell found.
virtual int IntersectWithLine(const double p1[3], const double p2[3], double tol, double &t, double x[3], double pcoords[3], int &subId)
Return intersection point (if any) of finite line with cells contained in cell locator.
This class implements the data structures, construction algorithms for fast cell location.
void FindCellsWithinBounds(double *bbox, vtkIdList *cells) override
Return a list of unique cell ids inside of a given bounding box.
int IntersectWithLine(const double a0[3], const double a1[3], double tol, double &t, double x[3], double pcoords[3], int &subId, vtkIdType &cellId, vtkGenericCell *cell) override
Return intersection point (if any) AND the cell which was intersected by the finite line.
int IntersectWithLine(const double p1[3], const double p2[3], double tol, vtkPoints *points, vtkIdList *cellIds, vtkGenericCell *cell) override
Take the passed line segment and intersect it with the data set.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods to print and obtain type-related information.
void BuildLocatorInternal() override
This function is not pure virtual to maintain backwards compatibility.
void ForceBuildLocator() override
Satisfy vtkLocator abstract interface.
vtkIdType FindCell(double pos[3], double vtkNotUsed(tol2), vtkGenericCell *cell, int &subId, double pcoords[3], double *weights) override
Find the cell containing a given point.
bool GetLargeIds()
Inform the user as to whether large ids are being used.
~vtkCellTreeLocator() override
detail::vtkCellTree * Tree
void FindCellsAlongLine(const double p1[3], const double p2[3], double tolerance, vtkIdList *cellsIds) override
Take the passed line segment and intersect it with the data set.
void FreeSearchStructure() override
Satisfy vtkLocator abstract interface.
void ShallowCopy(vtkAbstractCellLocator *locator) override
Shallow copy of a vtkCellTreeLocator.
void GenerateRepresentation(int level, vtkPolyData *pd) override
Satisfy vtkLocator abstract interface.
void BuildLocator() override
Satisfy vtkLocator abstract interface.
static vtkCellTreeLocator * New()
Constructor sets the maximum number of cells in a leaf to 8 and number of buckets to 6.
provides thread-safe access to cells
list of point or cell ids
a simple class to control print indentation
represent and manipulate 3D points
concrete dataset represents vertices, lines, polygons, and triangle strips
