public class FlowJSpotNoise

extends java.lang.Object

This class implements spot noise displaying of flow fields. On occasion you may wonder about why I coded it the way I did: the only reason is that the JDK 1.1.8 javac compiler contains a bug that has to do with variables local to a method that are put on the stack. All weird codes are workarounds around this problem. Copyright (c) 2000, Michael Abramoff. All rights reserved.
