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
-
findLeftLeaf
private void findLeftLeaf()
does the work
-
isWithinRadius
private boolean isWithinRadius(javajs.util.T3 t)
checks one Point3f for box-based distance- Parameters:
t
-- Returns:
- boolean
