Module 23 - Physics Engines - 2025-Mar-27

Overview

In this module we learn about physics and jobs of a physics engine.

  • Physics Engines
  • Job of a Physics Engine
  • Broad Phasing
  • Spatial Partitioning
  • Unity3D Physics
  • Oriented Bounding Boxes
  • SDL3 Examples of Collision

Slides and Class Content

Please note: Your in-class activity is graded. Your first attempt will be graded. You can use your notes and slides if you like. You have 1 week from the date of this module opening to complete the in-class activity. In-class activities are completed individually.

Audio/Video Recording

Note: Audio/Video recordings are made in a best effort in case you have to miss class or you would otherwise like to re-watch a portion of lecture. Occassional recording errors (e.g. missing sound, corrupted video, etc.) may occur, and I apologize in advance if a recording is not able to be made available.
