Inoculation from the need to understand vectors is not an option when writing game engines, they are everywhere; translations, rotations, projections, collisions, lighting, all involve vectors. While understanding vectors is required, understanding imaginary space, dimensions higher than the order of three, and obscure mathematical jargon in which vectors are normally dressed is not. It is, however sadly, the present state of the literature. This book breaks that mold and explains vectors, dot product, perp dot product, cross product, lines and planes, primitive collision detection and rotations from illustrations, logical explanations and simplified mathematical examples. If you know how to add, subtract, multiply and divide you can follow this book.
