Features
---------------------------

- Realtime editable, 3D based terrain (Unlike a heightmap based terrain, this allows for overhangs, tunnels, and user creation/destruction)
- Physics based collision and raycast support
- Infinite terrains made by paging sections in and out
- Voxel data is streamed from a variety of sources, which includes the ability to write your own generators
- Minecraft-style blocky voxel terrain, with multiple materials and baked ambient occlusion
- Smooth terrain using Transvoxel
- Levels of detail for smooth terrain
- Voxel storage using 8-bit channels for any general purpose


What This Module Doesn't Provide
-----------------------------------

- Levels of detail for blocky terrain
- Game specific features such as cave generation or procedural trees (though it might include tools to help doing them)
- Editor tools (only a few things are exposed)
- Import and export of voxel formats


How To Install And Use
-------------------------

Voxel Tools is a custom C++ module for Godot 3.1+. It must be compiled into the engine to work.

### Prebuilt binaries

Ready-to-use versions of Godot including the module exist, though they might not be 100% up to date.

- Tokisan Games (editor and export templates)
    - [Tokisan Games binaries](http://tokisan.com/godot-binaries)

- Master builds (editor)
    - Windows: https://github.com/Zylann/godot_voxel/actions?query=workflow%3A%22%F0%9F%9A%AA+Windows+Builds%22
    - Linux: https://github.com/Zylann/godot_voxel/actions?query=workflow%3A%22%F0%9F%90%A7+Linux+Builds%22
    - Warning, these can be unstable, as they come from the very latest commits. Click on one of the recent commits and a build artifact should be available.


### Compiling

Compiling the source yourself is the best way to get the very latest version.
Please see the [Getting Started Guide](doc/01_get-started.md) for instructions.

Roadmap
---------

These are some ideas that may or may not be implemented in the future:

* Texturing on smooth terrain
* Editor preview and authoring
* Improving LOD performance
* Other meshing algorithms (e.g. dual contouring)
* GPU offloading (Maybe when Godot 4+ supports compute shaders)
