In this article we will implement a two dimensional grid and its basic operations. We will visualize the results with HTML5 canvas and JavaScript so you could easily play with the source code and see how does it work.

We will discuss the idea of Perlin noise without hard digging into math details. Also we will implement Perlin noise on a two dimensional grid continuing our work from the previous procedural generation article.

Fractal noise or value noise is an algorithm which you apply to some other noise function. The result has multiple level details, sometimes looks cloudy and every time looks very interesting. Also many people confuse fractal noise with Perlin noise because they usually are used together.

Ray tracing is a computer graphics technique focused on processing of ray of light. Ray is presented as a geometrical line, and a scene is presented as a set of surfaces. Solving the problem of intersection a ray and a surface is where ray tracing technique begins.
