Opengl 2 -

#include <GL/glut.h> void display() GL_DEPTH_BUFFER_BIT);

I’ve been messing around with OpenGL 2.1 lately (I know, I know, it’s ancient), mostly for some retro demo coding and to understand the basics before moving to modern programmable pipelines. opengl 2

Here’s a minimal working example in C (GLUT/FreeGLUT): #include &lt;GL/glut

For those who didn't start there, OpenGL 2 introduced the shader model (1.10/1.20) and still fully supported the fixed-function pipeline. But in practice, most people associate "OpenGL 2" with immediate mode ( glBegin/glEnd ), glVertex , glMatrixMode , and lighting via glLight . void display() GL_DEPTH_BUFFER_BIT)

Anyone else still occasionally writing fixed-function OpenGL for fun? 😄
