Chapter 1
Vector Algebra
Vectors play a crucial role in computer graphics, collision detection, and physical simulation, all of which are common components in modern video games. Our approach here is informal and practical; for a book dedicated to 3D game/graphics math, we recommend [Verth04]. We emphasize the importance of vectors by noting that they are used in just about every demo program in this book.
Objectives:
To learn how vectors are represented geometrically and numerically.
To discover the operations defined on vectors and their ...
