Notes to the Grader:

• Page 8
  • In box 1, I still make a similar shape which I did in pervious workbook because I think this shape is good for praticing bezierCurveTo
• Train
  • For the required part:
    • I successfully connect the given points with bezier curves, and those curves will also be connected when add or remove any points
    • I draw the train and it can move along the curve; when drag any point, or add / removing any ponits, it will be still on the curve
    • Calculating the tangent lines and get the correct angles to rotate, the train moves with the correct direction, and there is a "yellow light" pointing to the front of movement
  • For any bouns parts:
    • I tried to do the arc-length parameterization and it looks working well: when check the box arc-length the trains will move with a constant speed. Also, when dragging / adding / or removing any points, the trains still move with constant speed on the remaining curves
    • I tried to draw trails on the curve, which are currectly placed vertical to the curve.
