Method Summary
`double` | `getHRange()` the distance (in radians) to consider two objects to be interacting, that is, intersecting for our purposes.
`boolean` | `preConsider(GeoExtent seg, GeoExtent region)` do inexpensive comparisons to determine if the two elements might intersect.

Method Detail

### preConsider

    boolean preConsider(GeoExtent seg,
                        GeoExtent region)

  do inexpensive comparisons to determine if the two elements might intersect.

  Returns:
    true iff further checks might yield intersection.

### getHRange

    double getHRange()

  the distance (in radians) to consider two objects to be interacting, that is, intersecting for our purposes.

  Returns:
    the maximum distance to consider touching. Must be non-negative.
