Applet shows a transverse wave traveling in the positive z direction. The vibrations of the particles can be set along any direction perpendicular to the z axis. The angle between the plane of vibration and the xz plane is shown in the top right corner.
Double clicking the mouse at any point in the applet area shifts the origin to that point. Dragging with mouse changes the orientation of the axes.
Maximizing the frame enhances the 3D feel a wee bit.
