This creates a new vector that is perfectly perpendicular to two others. It’s the "secret sauce" for finding which way a flat surface is facing. 2. Matrices: The Transformation Grid
This tells you how much two vectors "align." It’s used constantly in gaming to calculate lighting—the closer a surface faces a light source, the brighter it is. Matrices, Vectors, and 3d Math
The Building Blocks of the 3rd Dimension: Vectors and Matrices This creates a new vector that is perfectly
If a vector is a point, a is a set of rules for moving that point. Matrices are essentially grids of numbers that act as "operators." When you multiply a vector by a matrix, you transform it. Common transformations include: Translation: Moving an object from A to B. Rotation: Spinning an object around an axis. Scaling: Making an object bigger or smaller. 3.
