i've been working on a 3d game engine for a few months now and it uses sfml for window and input, i made my own 3d model format and an exporter for blender and im currently working on creating a scripting language/engine for it. writing a scripting language is super hard and i may abort the mission lol but my engine currently supports a small amount of things. lighting, texturing, billboarding, 3d model loading ( 3ds, md2, cell(mine), obj ), input, game states, 3d math and some sound. much more to come
