Installation

Use Ceto without a compiler​

For the ready-to-run Windows x64 viewer, follow First steps with Ceto. The v0.2.0 Ceto ZIP includes the Courtyard example and runtime resources. Extract all files, start Ceto.exe, then select Samples > Courtyard > world.scene. Download Ceto v0.2.0 for Windows x64. Version 0.2.0 is published as an experimental prerelease.

The requirements below apply to building Rhea from source.

Build requirements​

  • A C++17 compiler and the platform development tools.
  • CMake 3.24 or newer.
  • Git to obtain the engine checkout.
  • Python 3 for build-time Fabric and type registry generation.
  • Native dependencies required by the selected platform and graphics backends.
  • Network access when CMake downloads missing dependencies.

On Windows with MSVC, use a developer terminal. Ninja is required only when using a Ninja generator or preset. See Project Status for the platform validation status.

Obtain the engine​

Clone the engine repository:

git clone https://github.com/rhea-engine/rhea.git
cd rhea

The engine repository root contains Rhea/, Poseidon/, and the top-level CMakeLists.txt.

Use a published release tag or known commit for reproducible builds when available. Keep your engine revision aligned with the documentation you follow.

Build and verify​

Continue with Getting Started for the BasicApp build configuration, runtime assets, launch instructions, and first source change. That guide is the authoritative introductory build walkthrough.
