Designed for students, technical artists, and Unity developers alike, Essential Math for Game Devs is a hands-on guide to visualizing mathematical concepts through interactive tools built with Unity’s EditorWindow. From foundational vector operations like the dot and cross product to advanced topics such as quaternions and rotation matrices, this book blends theory with step-by-step C# implementations to make abstract math intuitive and practical. Each chapter introduces a core concept and guides you through the process of building your own visualization tool directly in the Unity Editor. By the end of the book, you'll have a strong grasp of geometric transformations, a deeper understanding of math for game development, and a personal toolkit of editor extensions to reinforce learning — all presented in a clear and accessible way for both beginners and experienced developers.
