This assignment is very similar to our class examples. The first step is to use "cross product" to get the points of the grid and use two integer sliders to simulate the location of the pebble. Then I can use the geometry distance to the module to calculate the distance between each point and the pebble. Then use the distance as input to calculate the corresponding sin wave and set the height of each cylinder. Noticed that since the distance is relatively small( usually < 360), and the frequency is not clear at first, so I add a distance amplify module to amplify the distance and feed the result to calculate the sin wave. At the same time, one slider controls the amplitude is added to highlight the change and another slider controls the offset to make sure there is no negative height.
