Somewhere I got stuck was: - I struggled setting up the bezier function. It took some time researching to understand what was happening. Something I figured out was: The bezier function. It looks so smooth! A strategy I used: Reading online forums for help, such as stackoverflow, various Python guide websites, etc. Something I'm wondering: I was wondering on how to parameterize the bezier control points, but thanks to Varun, I know now. Something I want to learn: Nothing specific at the moment. An idea for future: No new ideas at the moment.
