This PR fixes how triangular faces are decomposed into vertices and indices. The pre-increment resulted in the indices table skipping entry 0 and potentially overrunning the end of the vertices vector.
Note: this change completely overwrites the meshoptimizer library source
(from git SHA c21d3be6ddf627f8ca852ba4b6db9903b0557858)
without including any patches; a distance error metric patch is still
needed and will be reapplied in the next commit.
The changes elsewhere are due to a signature change for
meshopt_simplifyWithAttributes.
This cleans up a few more cases of uint32_t->uint64_t
Importantly this fixes an edge case in the axis-angle compression by
using the pre-existing Basis methods instead
This allows Godot to automatically compress meshes to save a lot of bandwidth.
In general, this requires no interaction from the user and should result in
no noticable quality loss.
This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.
Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.
Implements create_convex_shape in ImpoterMesh.
Note: ImporterMeshInstance3D::get_mesh() is safe.
The only dangerous function with side effects is ImpoterMesh::get_mesh()
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
Fix mistake making `set_custom_format` impossible to use.
Automatically forward custom flags in `SurfaceTool.commit`.
Add documentation in `SurfaceTool` and `Mesh` for custom channels.
Deprecate `SurfaceTool.generate_lod` and expose `ImporterMesh.generate_lods`.
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
* New plugin system to control the whole import workflow
* Can add options and run code at every import step (general, per node, mesh, animation, material etc.)
This constitutes a first version of these plugins. The ability to interact with the import preview dialog will likely be added later on.
Convert GLTF Document to use ImporterMeshInstance3D.
Add a GLTFDocument extension list and an extension for converting the importer mesh instance 3d to mesh instance 3d.
Use GLTF module when the editor tools are disabled.
Modified the render server to be less restrictive on matching blend arrays and have more logging.
Misc bugs with multimesh.
Always index the meshes.
