Part 1

In the app below, the 2D figure you see on the left is the same as the 2D figure you see on the right.
Slide the slider (lower left) all the way to the right.
What did you see happening above? Describe as best you can in your own words.
Now slide the slider and move the LARGE POINTS (on the left side) to create a pretty slick, cool-looking surface on the right!
