In this series of articles, we’ll walk through a basic, didactic software rendering scheme for three-dimensional graphics. We assume familiarity with high school geometry and vectors. In this first part, we will explore the mathematical preliminaries. Afterwards, we will implement the renderer using javascript canvas.

In this series of articles, we’ll walk through a basic, didactic software rendering scheme for three-dimensional graphics. We assume familiarity with high school geometry and vectors. In this first part, we will explore the mathematical preliminaries. Afterwards, we will implement the renderer using javascript canvas. Why do distant objects appear small? This is a fundamental question that we must consider. An object very far away from us appears small, and it increases in size as it approaches us.
