Detailed Description

Vector in the R³ space, with (x, y, z) components.

This class overloads several operators to make evaluating formulae easier.

The multiplication operator (*) can be used with a scalar argument (i.e., a float value), or with another vector, in which case it stands for the dot product.

The modulus operator (%%) represents a cross product.
