Math In Game Development Summit: Practical Quaternions: An Easy Guide to 3D Rotations for Non-Mathematicians

Patrick Martin  (Developer Relations Engineer, Google)

Pass Type: All Access Pass, Summits Pass

Topic: Programming

Format: Session

Vault Recording: TBD

Audience Level: N/A: I would like to deliver a virtual presentation only

Have you heard cool things about quaternion math but loose the thread as soon as someone starts talking excitedly about four dimensional hyperspheres? Join Patrick as explains how he visualizes, debugs, and works with quaternion math as a practical implementor rather than their pure mathematics. By the time you walk out, you'll see quaternions not as a mathematical oddity but as a collection of common operations you use day to day to solve real world puzzles.


Attendies will walk away with a practical model of quaternion mathematics as they relate to 3d video games.

Intended Audience

Attendies should be comfortable working with 3d games related maths but not be proficient. This will not be a notation heavy math talk but a collection of practical tips to accomplish common every day tasks with quaternion mathematics.
