<DL>
<DT><PRE>public class <B>PVector</B><DT>extends java.lang.Object</DL>
</PRE>
<P>
A class to describe a two or three dimensional vector.
<p>
The result of all functions are applied to the vector itself, with the
exception of cross(), which returns a new PVector (or writes to a specified
'target' PVector). That is, add() will add the contents of one vector to
this one. Using add() with additional parameters allows you to put the
result into a new PVector. Functions that act on multiple vectors also
include static versions. Because creating new objects can be computationally
expensive, most functions include an optional 'target' PVector, so that a
new PVector object is not created with each operation.
<p>
Initially based on the Vector3D class by <a href="http://www.shiffman.net">Dan Shiffman</a>.
