interpolate / voronoi
Example 1: show results from using the voronoi (nearest node) option of interpolate.
For each point in the sink grid, the nearest node is found from the source or background grid. The attribute value associated with the sink point is assigned the attribute value from the source node.
The output consists of GMV files.
The input consists of AVS and GMV files. The input deck for this example is lagrit_input_voronoi
Results from Example 1:
The objective is to test the ability of interpolate to find the nearest node in a coarse hex grid to each point of a refined triangle grid. The imt value of each found node is copied to the sink imt attribute. Image shows the imt colors of the coarse hex grid and the refined triangle sink grid. source hex and sink tri grids](image/vor1.gif”>
The objective is to test the ability of interpolate to find the nearest node in a quad grid and copy imt values to sink quad grid. Image shows both the irregular quad grid and the refined quad sink grid. source and sink quad grids](image/vor_rand.gif”>
The objective is to test the ability of interpolate to find the nearest node in a tet sphere and copy to a 2D triangle sphere surface. The 2D surface has a radius slightly smaller than the 3D sphere. Image on left is the 3D tet sphere. Image on right is the triangulated surface with imt values copied from the 3D source sphere. The ends have been cutaway to show the surface elements.
