Ricardo Buring 8812d27bc7 Restore edge and face support thresholds in 3D 2023-05-17 20:14:19 +02:00
Black-Cat d710af2e97
Fix precision in physics supports generation
Lower threshold for dot was (1.0 - threshold) which is incorrect.
Patch changes it to correct version sqrt(1.0 - threshold * threshold)

One Copyright Update to rule them all
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".

Malcolm Nixon 37e4f8befa Micro-optimizations of the GodotConvexPolygonShape3D::get_support function. Specifically this uses pointer-array-dereference rather than LocalVector<T> dereference as this performs range-checking on known-good indexes.
Added more comments. Changed loops back to classic for-iteration style.

Ricardo Buring 29ab86aa7d Fix collision detection for degenerate capsules
In GodotCapsuleShape3D::get_supports and
GodotCapsuleShape2D::get_supports, return a point instead of an edge of
length zero in case the capsule degenerates to a sphere or circle.

Juan Linietsky 71d2e38cb5 Optimize Convex Collision
Implements the Gauss Mapping optimization to SAT convex collision test.

* Described [here](https://ubm-twvideo01.s3.amazonaws.com/o1/vault/gdc2013/slides/822403Gregorius_Dirk_TheSeparatingAxisTest.pdf) by Dirk Gregorius.
* Requires adding of face information to edges in MeshData
* Took the chance to convert MeshData to LocalVector for performance.

Ricardo Buring 215c5458f5 GodotCylinderShape3D::get_supports: delete dead code 2022-09-28 21:37:37 +02:00
reduz 746dddc067 Replace most uses of Map by HashMap
* 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!

Rémi Verschelde c273ddc3ee Style: Partially apply clang-tidy's `cppcoreguidelines-pro-type-member-init`
Didn't commit all the changes where it wants to initialize a struct
with `{}`. Should be reviewed in a separate PR.

Option `IgnoreArrays` enabled for now to be conservative, can be
disabled to see if it proposes more useful changes.

Also fixed manually a handful of other missing initializations / moved
some from constructors.

PouleyKetchoupp d630269593 Fix contact generation with backface collision disabled
Replaced the previous implementation for backface collision handling (in
test_axis function from SAT algorithm) with much simpler logic in the
collision generation phase with face shapes, in order to get rid of
wrong contacts when backface collision is disabled.

Now it just ignores the generated collision if the contact normal is
against the face normal, with a threshold to keep edge contacts.

Added a special case for soft bodies to invert the collision instead of
ignoring it, because for now it's the best solution to avoid soft bodies
to go through concave shapes (they use small spheres). This might be
replaced with a better algorithm for soft bodies later.
