Class TriangularByteLattice

java.lang.Object
org.opensourcephysics.display2d.TriangularByteLattice
All Implemented Interfaces:
Drawable, Measurable
public class TriangularByteLattice extends Object implements Measurable
A TriangularByteLattice is an array where each array element can assume one of 256 values. Values can be set between -128 and 127. Because byte values larger than 127 overflow to negative, values can also be set between 0 and 255.
