LRLE

GPU-accelerated 3D terrain visualizer. Loads heightmap data from FDF files and renders them in real-time. WIP but it works.

Features

  • Cross-platform GPU rendering via wgpu
  • Interactive orbital camera with mouse and keyboard controls
  • Adjustable height scaling for heightmap visualization
  • Built-in egui UI panel with stats
  • Efficient mesh generation from heightmap grid data

Usage

cargo build --release
lrle terrain.fdf
lrle terrain.fdf --height-scale 2.0

Why

Wanted to get my hands dirty with real-time GPU rendering and wgpu. FDF files are a simple heightmap format - perfect for learning 3D visualization without dealing with complex model formats.
