Class CubeIterator
java.lang.Object
org.jmol.bspt.CubeIterator
Iterator used for finding all points within a box or a hemi-box
Obtain a CubeIterator by calling Bspt.allocateCubeIterator().
call initialize(...) or initializeHemizphere(...)
re-initialize in order to reuse the same CubeIterator

initialize
public void initialize(javajs.util.T3 center, float radius, boolean hemisphereOnly) initialize to return all points within the sphere defined by center and radius- Parameters:
center
-radius
-hemisphereOnly
-
-
release
public void release()nulls internal references -
hasMoreElements
public boolean hasMoreElements()normal iterator predicate- Returns:
- boolean
-
nextElement
public javajs.util.T3 nextElement()normal iterator method- Returns:
- Tuple
-
foundDistance2
public float foundDistance2()After calling nextElement(), allows one to find out the value of the distance squared. To get the distance just take the sqrt.- Returns:
- float
