The list is by no means exhaustive and may not be tailored or ideal to every individual.
What these tutorials are about
In this set of tutorials, you will learn how you can design numerical WebGL 2.0 applications without any direct calls to WebGL directives.
We will start by drawing a basic triangle, and then represent a rectangle with two triangles. We will build our computational fortress on the foundation of coloring a unit rectangle. Our codes will advance to looping and building recursive complex maps, and then we will advance to time marching problems.
You will get familiar with Abubu.js data structures, solver setups, and visualization tools.
We will also cover some examples of introducing user interactions into our computational codes.
