jplanetsun is an interactive java applet which implements the solution of the two-body-problem.
The applet uses the small sized 3d plugin blaxxun3d
which enables interactive 3d scenes in html pages. The 3D scene was constructed by writing a simple
VRML text file (using a VRML node subset as proposed by the new X3D standard)
which was postprocessed by a blaxxun-program to reduce size to a minimum.
Currently, the applet doesn't fully exhaust the possibilities of 3d, since the viewport
cannot be changed. But with this fixed perspective, the ellipse character of the planet and sun trajectories
are best visible.
