Description

Given a closed polygon boundary domain in the plane, this X-Function generates interior mesh by delaunay triangulation and resamples data points at the mesh nodes.

Examples

1. Import Resample.dat in \\Samples\Data Manipulation folder.

2. Set column D as X column, then column D, E will be used as boundary curve.

3. Type xy_resample -d in the command window to bring up the dialog.

4. Set column A, B as Input and D, E as Boundary Vertices. Enter 50 to the Number of Points on Edge box.

5. Click OK to run the X-Function.

Algorithm

Detail algorithms please read the NAG help, d06 - Mesh Generation.
