Java · LWJGL 3 · OpenGL

A game engine written from scratch, in public.

No engine, no editor, no framework doing the hard part. Just GLFW, buffers, shaders, and Java — figured out one problem at a time and recorded as I go.

Every step becomes a video first. Once it's out, I write the same thing up here, with the code you can actually copy and the parts I got wrong the first time.

• 01 Setting up LWJGL 3 with Gradle Dependencies, natives per platform, and a project that still builds in six months. planned
• 02 A window, a context, a loop GLFW window hints, the OpenGL core profile, and a fixed-timestep game loop. planned
• 03 The first triangle VAOs, VBOs, and the smallest pair of shaders that will draw anything at all. planned
• 04 Matrices, a camera, and JOML Model, view, projection — and where the transform actually goes wrong. planned

• → Your first triangle in LWJGL 3 Window, context, buffers, shaders — the whole path from empty file to pixels. read

What this is

Raster Pine is one person learning graphics programming the slow way, and leaving the notes behind. If you've read a modern OpenGL tutorial in C++ and wanted the Java version — or you've used an engine for years and never known what it was doing underneath — this is aimed at you.

Videos go up on YouTube. Written versions land in writeups, usually a few days later.
