void moab::AxisBox::closest_position_within_box | ( | const double * | input_position, |
double * | output_position | ||
) | const [inline] |
Find closest position on/within box to input position.
Find the closest position in the solid box to the input position. If the input position is on or within the box, then the output position will be the same as the input position. If the input position is outside the box, the outside position will be the closest point on the box boundary to the input position.

Check if two boxes intersect.
Check if two boxes are within the specified tolerance of each other. If tolerance is less than zero, then boxes must overlap by at least the magnitude of the tolerance to be considered intersecting.
