    Three Dimensional Shapes and Shading
    Three dimensional objects are not easy to represent on a 2D surface such as a page or screen. In this article, inspired by chapter 3 of Math for Programmers book, we look at the cross product of two 3D-vectors and representing the surface of any 3D object as a collection of triangles. The cross product can be used to …

    Two Dimensional shapes
    A vector has magnitude and direction. A single point in 2D space can be considered a vector from the origin (0,0) to that point. Vectors can be described anywhere in 2D space using a point for the start and a point for the end. Multiple vectors can be connected together to create 2D shapes. This article will discuss …
