If you want to learn how game engines and 3D graphics work and how to create your own engine, this project is for you.
The goal of this educational game engine project is to help you learn what happens under the hood, just like creating it helped me learn more about the technical details. It's not intended to be used for serious game projects, although you can use it to create your own games if you want to understand in detail what happens between the player's input and the final image on the screen. Along with the game engine I'm developing a sample game to incrementally drive the engine's requirements and demo its features.
This engine does many things in code running on the CPU that would normally happen in hardware, e.g., on the GPU. Also, it is implemented in Kotlin running in the JVM because of the educational focus, whereas a commercial game engine would typically be implemented in C or C++. As a result, although you can achieve pretty nice looking graphics with it, if you want decent framerates for your game you will have to pretend it's the nineties and you're programming for one of the early game consoles.
Note that the project is still in an early stage and will receive many significant and breaking changes.
Currently I am not taking any feature requests or bug reports.
