77 | /** |
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. | |
