78 * This is a demonstration of how to use the projection library. A projection
79 * creates a mutation of the coordinates of all the points in the model, creating
80 * virtual x,y,z coordinates. In effect, this is like virtually rotating the entire
81 * art car. However, since in reality the car does not move, the result is that
82 * it appears that the object we are drawing on the car is actually moving.
83 *
84 * Keep in mind that what we are creating a projection of is the view coordinates.
85 * Depending on your intuition, some operations may feel backwards. For instance,
86 * if you translate the view to the right, it will make it seem that the object
87 * you are drawing has moved to the left. If you scale the view up 2x, objects
88 * drawn with the same absolute values will seem to be half the size.
89 *
90 * If this feels counterintuitive at first, don't worry. Just remember that you
91 * are moving the pixels, not the structure. We're dealing with a finite set
92 * of sparse, non-uniformly spaced pixels. Mutating the structure would move
93 * things to a space where there are no pixels in 99% of the cases.
