public abstract class VisObject
extends java.lang.Object

The abstract base class of all objects which can be drawn on a VisCanvas. Every object has a transformation matrix which alters the object's display. Most methods that modify the object's transformation return the same object, allowing multiple transformations to be easily concatenated.

Matrix	getPosition() Returns the object's transformation matrix.
abstract void	render(VisRenderer r, VisWorld world, VisView v) Called by VisCanvas when it is time to render the object.
VisObject	rotateX(double t) Concatenate the object's current transform with a rotation around the X axis.
VisObject	rotateY(double t) Concatenate the object's current transform with a rotation around the Y axis.
VisObject	rotateZ(double t) Concatenate the object's current transform with a rotation around the Z axis.
