Leader: Bartlomiej Waszak

This tutorial will explain the details of the most frequently used math objects in video game programming. Topics will cover the basic and advanced parts of math. There will be many code examples presented using Unity and Unreal Engine. We will discuss common problems and solutions. Participants will have a chance to solve practical exercises in the Unity Engine during the class.

Part 1. "Floating-point numbers". A general overview of the IEEE-754 standard. Good practices.
Part 2. "Vectors". Distance, normalization. Scalar product. Vector projection. Cross product.
Part 3. "Interpolation". Linear and spherical interpolation. Bezier curves.
Part 4. "Matrices". A set of operations. A matrix as a transformation. Rotation matrix. Local and global space.
Part 5. "Quaternions". A set of operations. Comparison with matrices. Rotation quaternions. 4D dot product.
Part 6. "Forward and inverse kinematics". Skeletal animation. An example of an inverse kinematics solution.

Learning Objectives:
- In-depth knowledge of math used in game programming.
- Better understanding through a detailed analysis of several problems and solutions.
- Math presented with practical examples in popular game engines.
- Coding exercises with the assistance of the top industry expert.
