WSM::Vector2d Class Reference

Description

The Vector2d class stores a vector in 2D space.

The coordinates of the vector are accessed via public data members, x and y, or via the subscript operator, where indices 0 and 1 denote the x- and y- coordinates, respectively.

The operator '*' is the cross product of vectors, the operator '' is the dot product.
