An attempt at making an arm using FABRIK method. FABRIK stands for Forwards And Backwards Reaching Inverse Kinematics. This is so bad lmao, but it works better than I expected it to. I'm pretty sure TECHNICALLY this isn't FABRIK, but it was based on it.
http://andreasaristidou.com/FABRIK.html DEBUG 1: basic visualization, just a line. DEBUG 2: that line, but thicker and transparent so you can see the joints. DEBUG 3: colors each part and makes it taper, and shows all the points the pen draws to. V1.0 - release V1.0 - added rings to estimate how you can expect a joint to travel on debug modes
