- Made a bunch of changes to comply with Godot 4 API
- Use Godot's Vector3i and add the missing stuff with helper functions
- Transvoxel uses custom attributes API, the old way would not work
- Wrap MeshOptimizer in a unique namespace (see build script why)
- Added clang-format file for the module as some rules now differ
- Prevent thirdparty code and lookup tables from being clang-formatted
- Very likely full of runtime bugs that need fixing
Using per-size arenas behaves like a memory leak when
the user creates many VoxelBuffers of random sizes repeatedly.
Now memory blocks of the next power of two are used instead.
VoxelBuffers with power-of-two size will fit best, while also being
the most common. Non-power-of-two will use a bit more memory,
but such buffers are often temporary and less numerous.
- Still room for improvement, more parallelism is possible
- Started moving the data into its own structure
- Added locks to secure access to the data map (not truly used yet)
- Tasks with a tracker can schedule next ones when they complete
- Data loading responses also come with a callback, no buffer anymore
- Use new data grid to cache map access
With this mode enabled, editing anywhere becomes possible.
All edited blocks are loaded at once when the stream is assigned.
The generator is used on the fly to fill the gaps, instead of being
pre-emptively cached only nearby the viewer to allow editing.
Editing is still on the main thread, so this can cause stalls if
the generator is complex. There is also no controlled limit on how
much data gets loaded, so if edited data is larger than RAM, it will
not be playable. The feature is already quite usable, but more work
may be done for wider viability.
Before it was 0xffffffffffffffff, which the GDScript parser no longer
accepts because it is greater than INT64_MAX.
In the future we may rework this API.
- New importer, needs restart to switch but it's a limitation of Godot
- Might blow up if the scene spans a really big area, may be optimized in the future.
- The scene importer remains the default choice
- Promoted some ints to 64-bit to avoid oveflowing with large volumes or distances
- Handle a few cases of malloc failure
