04b6bfa88f Added in some of the uv calculation stuff from my experimental voxel engine, to maybe help wilth better seeing the changes that I want. 2019-05-17 20:12:08 +02:00

eec55057c3 Created more bindings for the library, and reworked the way the voxel getters and setters are bound, so it's more in line with godot's internal classes. 2019-05-17 18:38:04 +02:00

91a5c7ffa8 A bit of reorganization and tweaks: 
- Moved HermiteValue in its own file
- VoxelBuffer channels are now predefined
- Create DualGridGenerator for easier passing of data
- Chunk size is no longer hardcoded
- Respect padding when polygonizing voxels
- BUG: due to the above, the way we build the octree is now breaking the result as mentionned in the TODO
