This time, I'll explain both VAOs and GLSL. A VAO is a feature that lets you write VBOs (Vertex Buffer Objects), which have existed since OpenGL 2.x, more concisely. Starting with 2.x, VBOs were introduced, which send vertex data to the GPU in advance before drawing. A VAO encapsulates multiple VBOs.
This is more groundwork, but this time we'll specify the OpenGL version and display a window. OpenGL versions are very confusing, but thankfully, recent versions have become much less so. Using GLFW in Python, we'll specify OpenGL 4.0 for the context and display a window.
You can use modern OpenGL in Python. I picked up my pen to share how moving that is. In this series, I'll explain modern OpenGL features such as VAOs using Python, with code, as clearly as I can. Since this is part 1, it mainly covers an introduction and setting up the environment, and at the end we'll write a program that displays the OpenGL version your PC supports. By the way, I'll use GLFW, which lets you configure things like the context, rather than GLUT.
