Junkcraft

A simple Minecraft-like voxel game written in pure C and OpenGL.

Current features:

• Mesh culling rendering
• Basic random terrain generation with "looping" world
• Basic player movment physics - run and jump
• Break and place blocks
• Basic block variety and textures (in texture atlas)
• Generate terrain based on perlin noise
• Generate trees randomly
• Really basic, non-wrapping 3d cave gen
• Ore generation: bad random ore generation, probably will switch to noise based ore distribution
• Working day/night cycle with a sun/moon/starry skybox, and changing light levels

Planned features include:

• Technical
  • Frustum culling
  • Possible greedy culling
  • Improved AABB collision and movement physics
  • Skybox
  • Maybe some form of LODs
  • Terrain blend
  • Ambient occlusion
• Gameplay
  • Terrain generation and biomes: Partially working
  • Tree generation: Partially working
  • Cave generation: Really really basic
  • Day/night cycle
  • Entities
  • Local play
