vhud-rs | Pure Rust GTA V Radar & Minimap Engine

vhud-rs — Open-World Minimap, Radar Blip Projection & GPS Route Renderer in Rust

vhud-rs is a pure Rust math and state library that recreates GTA V's circular and rectangular minimap radar system for 3D games. It computes speed-reactive camera zoom, heading-rotated viewport matrices, edge-clamped offscreen directional blips, and A* GPS road navigation polylines.
