The dot and cross products are used all over the place in 3D graphics and games more broadly. Even without visualization, we can “test” some of these applications with the bare-bones Vec3 assembled...

Another way to multiply two vectors is called the cross product. Other names for it are the outer product and the vector product. Given that the dot product produces a scalar value and is also know...

One method of multiplying vectors together, called the dot product, is also called the inner product or the scalar product. Scalar product is a sensible name for the dot product, because the opera...

When you have values for $x$, $y$, and $z$, you can describe a point in three dimensional space. Something like $(3, 5, 1)$ or $(0, -2, 6)$, for example. Now let’s say you’ve got two points. Subtr...
