Opengl 2 !exclusive! -

Here’s a minimal working example in C (GLUT/FreeGLUT):

Diving back into OpenGL 2 – the fixed-function nostalgia opengl 2

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 . Here’s a minimal working example in C (GLUT/FreeGLUT):

#include <GL/glut.h> void display() glClear(GL_COLOR_BUFFER_BIT char** argv) glutInit(&argc

int main(int argc, char** argv) glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE

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

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.
