GRAVITY DEMO
------------------------------------------------------------------------------
by Krischan www.extrasolar.de

A simple 3D demo of gravitation in minib3d. Two bodies with different masses
affect each other using Newton's law of universal gravitation formula which
is F=G*((M1*M2)/r²). Includes a single surface path visualization using quads
to see the objects gravitation influence.

In this demo I've used the mass of our sun for the star and the mass of our
planet. You can interact with some keys use the mouse to rotate and zoom the
scene.
