The site LearnOpenGl made by Joey de Vries learns you how to program in OpenGl. His example programs are in C++. Here you find the JavaScript counterparts. His site and this site have seven parts each having a number of chapters. Om his site you find the tutorials for learning OpenGL.
The results of our programs (now using javascript) can be seen using the links below (not all the programs of Joey are implemented). Our source code can be downloaded from this github site. We also have some extra programs. Some explanations on these programs and also on the use of Typescript can be found at drikus.net.
Every part can be seen as a project on itself.
