About Vangers

Vangers (1998) is a legendary open-world racing/RPG game by K-D Lab. It features a unique voxel-based terrain engine and a surreal post-apocalyptic world.

vange-rs is a Rust reimplementation of the Vangers rendering engine with modern hardware-accelerated graphics via wgpu (WebGPU/Vulkan/Metal/DX12).

Features

Multiple terrain rendering strategies: ray-traced, voxel-accelerated, sliced, painted, and scattered. Full physics simulation ported from the original game. Cross-platform: Windows, macOS, Linux, and now Web.

Requirements

The web demo uses a procedural test level and needs no external data. The desktop version requires the original Vangers game data (available on Steam or GOG).
