## Detailed Description

Implements the Natural Neighbor Interpolation algorithm for the geographic dimensions of the grid.

Implements the Natural Neighbor Interpolation algorithm of Sibson (1980, 1981). This technique interpolates values stored on a Delaunay triangulation. Returned values are continuous everywhere and smooth everywhere except the vertices of the triangulation. Implementation of the algorithm is described in detail in Hipp et al. (1999).

## ◆ getInterpolatorType()

virtual const GeoTessInterpolatorType & geotess::GeoTessPositionNaturalNeighbor::getInterpolatorType | ( |  | ) | const
| inline virtual

Retrieve the type of interpolation that this GeoTessPosition object is configured to perform. Either InterpolatorType.LINEAR or InterpolatorType.NATURAL_NEIGHBOR.

Reimplemented from geotess::GeoTessPosition.

Definition at line 147 of file GeoTessPositionNaturalNeighbor.h.

## ◆ getMemory()

virtual long geotess::GeoTessPositionNaturalNeighbor::getMemory | ( |  | ) |
| inline virtual

Retrieve the amount of memory consumed by this GeoTessPosition object.

## ◆ update2D()

virtual void geotess::GeoTessPositionNaturalNeighbor::update2D | ( | int | tid | ) |
| protected virtual

Update the vertices and their associated interpolation coefficients, that will be used to interpolate new values. Uses the natural neighbor interpolation algorithm originally proposed by Sibson, R. (1980), A Vector Identity For Dirichlet Tessellation, Proc. Cambridge Philosophical Society, 87, 151-155. The algorithm is described in detail in Hipp, J. R., C. J. Young, S. G. Moore, E. R. Shepherd, C. A. Schultz and S. C. Myers (1999), Parametric Grid Information in the DOE Knowledge Base: Data Preparation, Storage, and Access, SAND99-2277, Sandia National Laboratories Report.
