quickly locate points in 3-space
vtkStaticPointLocator is a spatial search object to quickly locate points in 3D. vtkStaticPointLocator works by dividing a specified region of space into a regular array of cuboid buckets, and then keeping a list of points that lie in each bucket. Typical operation involves giving a position in 3D and finding the closest point; or finding the N closest points.
vtkStaticPointLocator is an accelerated version of vtkPointLocator. It is threaded (via vtkSMPTools), and supports one-time static construction (i.e., incremental point insertion is not supported). If you need to incrementally insert points, use the vtkPointLocator or its kin to do so.
- Warning
- This class is templated. It may run slower than serial execution if the code is not optimized during compilation. Build in Release or ReleaseWithDebugInfo.
-
Make sure that you review the documentation for the superclasses vtkAbstactPointLocator and vtkLocator. In particular the Automatic data member can be used to automatically determine divisions based on the average number of points per bucket.
-
Other types of spatial locators have been developed such as octrees and kd-trees. These are often more efficient for the operations described here.
