how to create your own game engine with java

Get LWJGL running and put a window on the screen, with an OpenGL context, and call the following sequence: glClearColor(0.25f, 0.50f, 0.75f, 0.0f) Set up your build environment / Git / whatever, get an executable built and a README so you know what the fuck is going on five years from now when you find this strange directory on your computer.

There's a few steps to get this up and running when you are doing this 'from scratch' (nothing is from scratch, says Carl Sagan, but you know what I mean). Personally I would start with LWJGL but make up your own mind. This is basically the choice for doing work in Java, the main question is whether you want to use LWJGL by itself or use something on top of it like libgdx. You will probably be writing OpenGL code using LWJGL. It's good because the libraries you need for doing this are commonly available and fairly stable, and it's bad because there are a lot of articles and tutorials out there which teach modern techniques (game -> buffers -> shaders -> pixels) and outdated techniques (game -> immediate mode -> fixed pipeline -> pixels), and it can be daunting to sort through them.

What I see in the picture looks like it's probably rendered with a standard GPU pipeline for 3D graphics, with what looks like circa-2000 graphics capabilities (hey, it's the rocket laucher from Q3A!).
