Flood 3D is a general-purpose C++ 3D engine (and tools) which has been in development since 2008. For our graphics API we opted for OpenGL which is highly portable between pretty much all platforms.
Our main goal is to make a usable 3D engine suitable to make games and simulations. The project was started mostly for learning purposes but also because we found there was no open-source integrated game engine that met our needs (and also because it’s so much fun!).
Aside from the engine, we also have a full-featured editor, that complements the functionality provided by the engine.
It is being developed by a team of mostly portuguese developers, led by triton.
