If the grid method is natural neighbor a Natural Neighbor tab will be added to the Grid form.

 

 

The following can be edited on this tab:

 

Show Triangulation: Check this box to show the triangulation between natural neighbor triplets in the data.

 

Line Style: Click this button to change the line style used to show the triangulation. A Line Properties form will be displayed where the style, color, and width can be selected. If no triangulation is being shown this field will not be displayed.

 

Voronoi Interpolation: Check this to use Voronoi interpolation for the grid.

 

Minimum Inner Angle: This is the minimum angle to use for the Voronoi interpolation.

 

Barycentric Interpolation: Check this to use barycentric interpolation for the grid.

 

Extrapolate beyond convex hull: Check this box to extrapolate grid node values beyond the convex hull of the data.

 

Number of Triplets to use for Extrapolation: This is the number of natural neighbor triplets to use when extrapolating beyond the convex hull of the data.
