# Voxirae

> Voxirae is a voxel game engine written in C++20 on Vulkan 1.3 with Slang shaders. It ray-marches worlds of 5 cm voxels on the GPU out to an ~8 km horizon (32 km in big-world mode), with real-time global illumination, FFT oceans, volumetric clouds, weather and seasons, and ships with gameplay, Jolt physics, dedicated-server networking, audio, an HTML/CSS game UI and an editor. Status: closed beta (sign up at https://voxirae.com/#beta). Release window: Q2 2027.
