This project adds a smooth voxel terrain system to godot. More precisely, it uses an octree to store an SDF, which is then meshed using a custom version of surface nets. Level of detail systems are in place for large viewing distances.

• Note, it has only been tested for Windows 11.
• Build the source using scons to your target platforms.
• move the contents of the addons folder to the addons folder in your project.

• Please refer to the demo scene to see how to use the terrain system.

Contributions are welcome! Please fork the repository and submit a pull request.

In particular, here are some areas of interest, in no particular order of importance:

• Use TBB concurrent(priority)queue for the mesh schedular to ensure greater compatibility.
• Fix build/release pipeline on github.
• Optimizing LOD connections, i.e. remove the overdraw/duplicate triangle generation.
• Multi-material support.
• Multithreaded octree generation.
• Optimize generating colliders, it causes quite a performance impact.
• Optimize chunks, we likely want to use some sort of object pool as we're dealing with thousands of nodes.
• Improve thread management.
• Add more interesting SDF options:
  • Combine multiple existing SDFs based on boolean operation (e.g. OperationSDF, that takes 2 SDF references and an enum to select the operation).
  • Better noise based SDFs for more realistic terrain.
  • SDF based on an arbitrary triangle mesh.
• Documentation & icons.
• Navigation system.
• Dual contouring extension.
