// This is for the Motion Machine Box Figure Applet format description.
// The Applet reads this file and creates the applet, most likely
// seen on the previous page.  The applet is curently set up to 
// animate when a user drags the mouse.  I did this to initially
// get a grasp on the speed and look of the animation but left it
// because I liked the degree of control while experimenting.
// Below are descriptions for how to use this file followed by the
// descriptors themselves.
//
// The instructions for this file-format are as follows:
//
// 1. The major functions are translate, rotate, and their variations
//    described below.  translate takes the relative direction (local)
//    and the number of pixels to move (you can use fractions if desired).
//    rotate takes a direction (x,y,z) and a fraction which will
//    be a fraction of Pi (i.e., rotate x,.25 rotates about the relative
//    x-axis 0.25*Pi radians)
//
// 2. To set the initial view, use the translate-initial and
//    rotate-initial functions, exactly like the rotate and translate above
//
// 3. To do rotation and translation animations, use rotate-animate and
//    translate-animate.  They both take the direction, the "scheme" and
//    amount as above.  There are currently six "schemes", which
//    describe the value for animation at a certain time.  The schemes are
//    indexed from t=0 to t=9 currently as follows:
//
// Scheme 0: 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0
// Scheme 1: 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0, 1.0, 0.0
// Scheme 2: 1.0, 2.0, 3.0, 4.0, 5.0, 5.5, 4.0, 3.0, 2.0, 1.0
// Scheme 3: -10.0, -9.0, -8.0, -7.0, -6.0, -5.0, -4.0, -3.0, -2.0, -1.0
// Scheme 4: 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0
// Scheme 5: -1.0. 1.0, -1.0, 1.0, -1.0, 1.0, -1.0, 1.0, -1.0, 1.0
//
//    By calling one of these schemes, the Motion Machine does a linear
//    interpolation through time, finds the value, and then multiples
//    the amount of rotation or translation you provide by that amount
//    in time.  So, for schemes, 0, 1, 2, and 5, you end up getting
//    a periodic effect. I.e, rotate-animate x,1,.25 rotates around the
//    local x-axis by Pi/4 radians, starting at t=0 and as t goes to 1,
//    the amount of rotation decreases to zero, then back to 1.0 * Pi/4
//    at t=2, etc.
//
//    I hope to allow the user to specify what kind of schemes they 
//    want to use either through the applet or simply this file.  Plus,
//    it would be nice to give the user the chance to use a smoother,
//    non-linear interpolation.
//
// 4.  drawBox takes the xlo,ylo,zlo,xhi,yhi,zhi coordinates and
//     draws the box accordingly.  Since the java applet starts with the
//     top left corner as (0,0), it takes a while to get used to this.
//
// 5.  To push onto the stackm use {, to pop, use }.  For people
//     unfamiliar with data structures, this could be confusing,
//     so just leave the { and } where they are, or experiment
//     to make a new creature until it makes sense.
//  
// 6.  Comments are done with // I used these to label the body
//     parts to make things easier.
