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.
While the vertex shaders used to update the meshes aren't actually rendering to the framebuffer, they may still refuse to run with some framebuffers bound - such as XR with multiple views.
This also fixes RENDERING_INFO_TOTAL_PRIMITIVES_IN_FRAME for the RD renderers as it was incorrectly reporting vertex/index count at times
This also adds memory tracking to textures and buffers to catch memory leaks.
This also cleans up some memory leaks that the new system caught.
Fixes bug where bounding box of 1 unit was used in some skinned models and had wrong LODs.
(this could become very large if the mesh is scaled, such as FBX conversions)
Also fixes a mistake in calcualting bone index.
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".
This uses a similar multipass approach to blend shapes
as Godot 3.x, the major difference here is that we
need to convert the normals and tangents to octahedral
for rendering.
Skeletons work the same as the Vulkan renderer except the bones
are stored in a texture as they were in 3.x.
This includes collision (2D SDF, Box, Sphere, Heightmap),
attraction (Box, Sphere), and all sorting modes.
This does not include 3D SDF collisions, trails, or
manual emission.
This allows using texture_2d_get on all platforms which is needed for the get_image function
This commit also fixes some OpenGL warnings on the Web platform that came from attempting to map a buffer with zero length
* 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!
