Raindrop

I was challenged to make a raindrop in Twoville, and here’s my response:

  

    with viewport
  center = [0, -2]
  size = [10, 11]

with path()
  closed = false
  color = [0.3, ~, 1]
  jump().position = [0, 3]
  with cubic()
    position = [-2.579, -5.07]
    control1 = [-0.344, -1.369]
    control2 = [-3.246, -2.392]
  with mirror()
    position = :zero2
    axis = :up

    
    
    
  
  
    

    with viewport
  center = [0, -2]
  size = [10, 11]

with path()
  closed = false
  color = [0.3, ~, 1]
  jump().position = [0, 3]
  with cubic()
    position = [-2.579, -5.07]
    control1 = [-0.344, -1.369]
    control2 = [-3.246, -2.392]
  with mirror()
    position = :zero2
    axis = :up

  
  expand

The exercise helped me fix an issue with mirror. Previously if the middle vertex was not on the mirror axis, I automatically inserted a straight line segment to bridge the gap between the mirrored segments. That produced more of a Hershey’s Kiss then a raindrop. Now I can insert a cubic Bezier to maintain the curvature.
