In this video, we start by integrating our updated RigidBody class and its new model transformation matrix with the face intersection algorithm to transform points when checking for a collision. Then, we write a new collision algorithm, this time for intersection between a face and a sphere. • Math Stack Exchange Question: https://math.stackexchange.com/questions/943383/determine-circle-of-intersection-of-plane-and-sphere • Geogebra: https://www.geogebra.org/3d/rb4npbc6 • Website: https://michaelg29.github.io/ • Twitter: https://twitter.com/MichaelGrieco10 • Discord: https://discord.gg/Uj54bDF • This Github Repo: https://github.com/michaelg29/yt-tutorials • This Playlist:    • C++ OpenGL Tutorial
