Project mention: 3D and 2D: Testing out my cross-platform graphics engine | news.ycombinator.com | 2024-04-02
I am glad people are working on it!!
Have you seen Kha by any chance? It has similar goals. I find it quite awesome, but it won't gain mass adoption for a bunch of reasons. https://github.com/Kode/Kha
Someone built an immediate mode renderer on top https://github.com/armory3d/zui, which is utilised by ArmorPaint https://armorpaint.org. I also use Zui for my own bespoke 2D game engine.
I find this tech and tooling really quite amazing (just look at how little source code Zui has) given just how small the ecosystem around it is. I think Kha really illustrates what can be achievable if the lower levels have robust but simple APIs, just exposing the bare minimum as a standard for others to build upon.
For the kind of project I work on (mostly 2d games), I think it would really awesome if your framework also supported low level audio, and a variety of inputs such as keyboard, mice, and gamepads. If it also had decent text rendering support it would basically be my dream library/framework.
