This is a much simpler attempt to solve the same problem as #76060, but without breaking any compatibility.
* Adds a description of what model space is in the Vector3 enums (MODEL_* constants). This has the proper axes laid out for imported 3D assets.
* Adds the option to `look_at` using model_space, which uses Vector3.MODEL_FRONT as forward vector.
The attempt of this PR is to still break the assumption that there is a single direction of forward (which is not the case in Godot)
and make it easier to understand where 3D models are facing, as well as orienting them via look_at.
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".
By popular demand, restoring the helper properties to rotate objects in degrees.
Affected are local and global rotations for:
* Node2D
* Node3D
* Control
"less" should be used for quantity, rather than "lesser".
Existing scripts that use `or_lesser` in `_get_property_list()`
will need to be updated to account for this change.
Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
* Made the Basis euler orders indexed via enum.
* Node3D has a new rotation_order property to choose Euler rotation order.
* Node3D has also a rotation_mode property to choose between Euler, Quaternion and Basis
Exposing these modes as well as the order makes Godot a lot friendlier for animators, which can choose the best way to interpolate rotations.
The new *Basis* mode makes the (exposed) transform property obsolete, so it was removed (can still be accessed by code of course).
* New track type BLEND_SHAPE
* Blend shapes are imported via this new track type
* Processing is more optimized (no longer relies on variants)
* Modified the Blend Shape API in MeshInstance3D to use indices rather than StringNames (more optimizes)
* Promo: Fixed a small bug in gizmo updating in Node3D that affected performance
Dedicated BlendShape tracks are required for both optimization and eventually implementing them in animation compression.
