bug in segmentLocator #211

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When the query point is far outside the segment bounding box, the radius 
(distance from the query point to the nearest filled cell) becomes very large.  
This radius is used to compute an index matrix which is filtered down to be 
with the grid and with in the search radius.  The problem is when the radius is 
too large the initial matrix is too big for memory. See lines 207-218 or 
segmentLocator.py in cg.

Added Unit Test what demonstrates the problem. Still looking for a solution.

Using a combination of the "old way" new way seems to solve the problem.  The 
"old way" using a query_ball_point when the query point is far outside the 
bounding box of the original segment data.

Need to clean up _kd2.
