irrlicht VS Solar 2D (formerly Corona SDK)

The Irrlicht Engine seams like a better idea then. https://irrlicht.sourceforge.io/ it is supported and has a small community. Source: almost 2 years ago

I'd recommend Irrlicht Engine. It was very popular during mid-to-late 2000's , and it to my knowledge it still supports OpenGL 1.x as well as its' own software renderer. I once had a PC similar to your specs in 2008, and Irrlicht ran decently alongside ODE physics engine. Source: about 2 years ago

The make or break moment for me was working on an indie game dev team when I was a teenager. I joined a team and was immediately mentored in a way that made programming and code make sense. We developed using open source engines like Irrlichtand Ogre3D, where my mentor was able to detail what came with the different available libraries, and how to utilize them to create a game. He would assign us to create... Source: over 2 years ago

Although primarily intended for games, Irrlicht is a relatively simple library (compared to a full game engine). https://irrlicht.sourceforge.io/. - Source: Hacker News / over 2 years ago

By all accounts they're perfectly serviceable frameworks! It's just I only listed things I have direct experience with. Source: over 2 years ago
