Class PickUtils

java.lang.Object
  edu.sdsc.mbt.util.PickUtils

public class PickUtils

extends java.lang.Object

This class provides a number of utility methods for handling picking and subsequent selection. Provides pick-level behavior mapping (eg: Atoms->Residues->Fragments->Chains). Provides closestAtom method to determine the closest atom relative to a specified StructureComponent and point in 3D space.
