Modelling Approach

I created seven groups in Dynamo to achieve the ripples on a pond:

  1. Grid of points. Number slider and lists were used to vary the number of points in x and y directions and the spacing.
  2. Pebble. Number Slider was used for the x and y coordinates.
  3. Compute distances. Distance was between pebble and each of the points on the grid.
  4. Calculate cylinder heights. The wave function used was Cylinder Height = Base Offset + Amplitude x Exponential Decay Factor * Sin(360° x (Distance/Wavelength))
  5. Create cylinder masses.
  6. Set cylinder radius.
  7. Set cylinder height.
