Terra is a voxel engine composed of multiple modules. Currently, those are:

• terra-core: public, safe and documented APIs
  • For manipulating blocks in the world, you only need this
• terra-meshgen: mesh generators to visualize data
  • Also, texture management utilies
  • Uses only safe terra-core APIs; you'll need to provide the renderer
• terra-offheap: implementation of terra-core that uses offheap memory
  • NOT A SAFE, PUBLIC API (memory corruption is possible if misused)
  • Direct usage in application code should be minimized
• terra-io-files: terra-offheap data saving and loading using files
• terra-net-*: networking server and client using Aeron with terra-offheap
  • Not a full solution for multiplayer voxel game
• terra-testgame: simple, ugly, singleplayer voxel world
  • Does not use nearly all Terra features
  • Did I mention it is ugly?

Dependency tree:

• terra-core
  • terra-meshgen
  • terra-offheap
    • terra-io-files
    • terra-net-core
      • terra-net-server
      • terra-net-client

terra-testgame depends on everything but networking parts of Terra.
