How does text rendering work?
The process of transforming font outlines into pixels is called rasterization. The operating system’s text-rendering engine places the outline (ie the shape) of each character at the desired font size on a pixel grid. Next, it colours all the pixels whose centre is inside the outline (see image below).

How do you draw a line in modern OpenGL?
To draw a line strip with N segments, 6*(N-1) vertices have tpo be processed. We have to create an “empty” Vertex Array Object (without any vertex attribute specification): glGenVertexArrays(1, &vao); glBindVertexArray(vao); And to draw 2*(N-1) triangle ( 6*(N-1) vertices):
