Voxel Tools for Godot

C++ module for creating cube-esque voxel worlds in Godot Engine.

Setup

Install the contents of the repo in a folder under "modules/", named "voxel".

IMPORTANT: if you clone the repo, Git will create the folder as the repo name, "godot_voxel". But because Godot SCons scripts consider the folder name as the module's name, it will generate wrong function calls, so you must rename the folder "voxel".

Features

• Compact voxel storage using 8-bit channels like images
• Calculates meshes based on grid of voxels. Only visible faces are generated.
• Vertex-based ambient occlusion (comes for free at the cost of slower mesh generation)
• Voxels can be of any shape, not just cubes (not fully accessible yet but present in code)

Ideas TODO

• VoxelMap node for infinite voxel terrain
• VoxelStreamer node to put on players so terrains know which voxels to load around them
• Physics!
• Make voxels editable
• Support internal threading
• Support saving and loading
• Promote classes to Node and Resource for better editor experience
• Interface for terrain generation modules (I don't plan to integrate a noise library in this module, unless it's integrated in Godot core)
• Support structure generation (anything that is bigger than one voxel)
• Convert any imported meshes to Voxel-compatible meshes (to comply with a few optimizations)
• Generate Mesh resources from voxels so they can be used in the editor as MeshInstances
• Import resources from other editors like Magicka-voxel
• Volumetric grid algorithms: fluids, pathfinding, lighting...
