kyub

C99 voxel game built on Kiln and Vulkan.

Overview

A chunk-based world with procedural biomes, caves, and sea-level water. Kiln supplies the Vulkan renderer, archetype ECS, platform layer, camera, physics, and UI. Kyub handles terrain, block definitions, inventory, and game systems.

Features

• Three distance-based LOD levels with chunk frustum culling
• Face-culled voxel meshes with ambient occlusion
• Procedural biome terrain, cave carving, and sea-level water
• Versioned binary chunk saves with stable block IDs and periodic flushing
• Block placement and breaking, hotbar, inventory, and debug overlay
• Native Linux builds and Windows cross-compilation through Nix

Notes

The shared engine lives in Kiln; Kyub consumes it as an external dependency. Engine code and game-specific systems can evolve separately.
