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.
