GEOTREE2_SizeOfSearchBox
parameter for the bintree-search of the neighborhood of MESHFREE points
In order to find the CANDIDATES of neighbors to a point,
MESHFREE collects all points from the search-tree cells (blue cells in the picture)
that intersect with a box of size H. The grey marked cells are the ones containing all condidates. One can imagine, that especially in 3D
this is still a big number of points.
To reduce the effort, one can reduce the size of the search box by the factor \( \alpha\)=GEOTREE2_SizeOfSearchBox
still coming out with sufficiently many candidates, but saving some computation time.
Default:
GEOTREE2_SizeOfSearchBox = 1.0
