Constructor Detail

ZBasicApplet

public ZBasicApplet()

Creates a new basic Jazz applet. It consists of a simple Jazz scenegraph mapped to a simple component in an applet. The scenegraph consists of a root, a node, and a camera that looks onto that node, plus a surface that is mapped to the window. Each of the scenegraph elements can be used via the accessor functions.
