Craft-rs

A Minecraft clone written in Rust, ported from Craft by Michael Fogleman. Uses software rendering via portablegl-rs — no GPU required.

Features

• Procedural terrain generation using Simplex noise
• 64+ block types (grass, sand, stone, brick, wood, flowers, etc.)
• Block placement, destruction, and eyedropper picking
• Ambient occlusion and dynamic lighting
• Day/night cycle with smooth lighting transitions
• Frustum culling for efficient rendering
• Flying mode and collision-based walking
• Software-rendered — runs without a GPU
