Rhea Engine

Rhea is an experimental modular C++ framework for virtual worlds and interactive 3D applications. It is intended for developers who want to compose and extend the engine's subsystems using familiar C++ and CMake tools.

The runtime, renderer, and selected capabilities are assembled from libraries and Fabrics. Standard CMake integration works without requiring mwpkg. An editor is planned but is not included in the initial public release.

Start here

Try a scene without writing C++: follow First steps with Ceto to open the Courtyard, explore it, and edit its objects and colors. The v0.2.0 Windows x64 ZIP bundles the viewer and example; the guide explains download, extraction, startup, and controls. No compiler is needed.

Develop with C++: check the installation requirements, then follow Getting Started to build and modify BasicApp. Continue with your first independent project and Architecture.

See Project Status for validation gaps and limitations, and Roadmap for proposed milestones.
