This applet uses JOGL, the Java implementation of the OpenGL graphics
API. When this page loads, you might be asked to "trust" a certificate
from Sun Microsystems, which provides the JOGL libraries.
The applet lets you view and manipulate several three-dimensional surfaces.
You can rotate the surface by clicking-and-dragging with the left mouse button.
Use the right mouse button to drag the surface around. Drag with the middle mouse
button (or left mouse with the ALT or option key) to zoom in and out.
By default, surfaces are drawn in a GLJPanel component. The applet can also
display the surfaces in a standard JPanel, using a GLPbuffer to do the OpenGL
rendering. You can switch between these two rendering modes using a command in
the "Options" menu. This allows you to compare the performance of the two
methods.
