Easy fix Memes

You know that moment when you're debugging for 3 hours trying to figure out why your 3D rendering looks like a Picasso painting had a baby with a glitch art exhibition? Then you realize you forgot to enable depth testing and suddenly everything just... works. One line of code. glEnable(GL_DEPTH_TEST) . That's it. Without depth testing, OpenGL just draws triangles in the order they're submitted, turning your beautiful 3D scene into an abstract art piece where far objects render on top of near ones. The Z-buffer sits there unused, watching you suffer. The fix takes 2 seconds. The debugging? That's your entire afternoon gone. Graphics programming: where forgetting one flag turns your game engine into modern art.
