GLART Week 2 Assignment

1) Simple solar system.

    Add a moon that orbits earth in this basic solar system. Starting with GLART_2_orbit.java.
    add another sphere and isolate the rotation so that it orbits around the earth without
    affecting Mars.  If you want to explore this further try adding another planet to the
    solar system. Add two moons to it.  Try adding a planet that has a tilted axis.

    See images below


2) Explore modelview transformations

    If you have ideas for something you would like to try, feel free to experiment.
    Be sure to use glTranslate() to vary position, glRotate() to vary orientation,
    and glScale() to vary the size of whatever shapes you are drawing.
