Neon Horizons: Building a Vapourwave 3D World in OpenGL (C++)

Support the channel, visit patreon.com/ncot_tech In this video I build a classic vapourwave scene from scratch using C++ and raw OpenGL. No game engines, no shortcuts—just direct graphics programming. The scene features the iconic retro grid floor, distant mountains, and a glowing neon sunset sky inspired by 80s aesthetics. I walk through the full process of how the scene works, including the C++ code structure, how the shaders create the vapourwave look, and how the geometry is rendered using OpenGL. Along the way I also show some of the mistakes and debugging steps that happened during development, which helps illustrate how real graphics programming problems get solved. -- Credits -- Music by Karl Casey @ White Bat Audio Contains clips from Robocop (c)1987 Orion Pictures Amstrad CPC 464 Photograph by Rama, Wikimedia Commons, Cc-by-sa-2.0-fr Billingham ICI Plant across back gardens, Billingham, Cleveland © Copyright Pete Chapman Fort Lauderdale Motel Barry Lewis https://www.flickr
