We learned about the grid method. It allows us to instruct an artist that knows how to copy a picture from a grid, how we want the picture copied. This can be achieved by controlling the grid the artist will copy the picture into. The grid method relies on a box. So we better should get to know our boxes.

Above you find a pictorial representation of a box. It is defined by three vectors, a, which is red in the picture, b which is orange in the picture and c which is purple in the picture.

# #![allow(unused_variables)]
#fn main() {
/// A Box represents the area and position that we will draw in.
#[derive(Debug, PartialEq, Clone, Copy)]
pub struct Box {
    /// Determines the origin of the drawing area, used to position the box.
    pub a: Vector<f64>,
    /// Determines the x axis of the box.
    pub b: Vector<f64>,
    /// Determines the y axis of the box.
    pub c: Vector<f64>,
}
#}

The above struct is a literal conversion from the picture. If you are wondering what these Vectors are, take a look at the documentation.
