* Particle shaders now have start() and process()
* Particle collision happens between them.
* The RESTART property is kept, so porting an old shader is still possible.
This fixes the problem of particle collisions not functioning on the first particle frame.
-Used a more consistent set of keywords for the shader
-Remove all harcoded entry points
-Re-wrote the GLSL shader parser, new system is more flexible. Allows any entry point organization.
-Entry point for sky shaders is now sky().
-Entry point for particle shaders is now process().
Several optimizations in the way solver islands are processed in both
2D and 3D physics:
- Use LocalVector instead of linked list to avoid cache misses (with
persistent storage based on worst case scenario)
- Remove pairs when setup fails (no valid contact) to avoid unnecessary
solving of non-colliding rigid bodies just to return immediately
Fixes#46181
CameraServer.add_feed() takes a CameraFeed object type as parameter.
Passing in another type of data while binding the method it will make
tha parameter null.
Added a check for null which returns from function and does not make the
engine crash anymore.
The program would fail if the parameter is passed as null in set_primary_interface because
in the print_verbose, the get_namea) method is called on the parameter and this causes a
failure if the parameter that was passed is null.
Same fix was done in 3.x also and it seems to be present in master too.
The moment of inertia calculation for BoxShape is:
```
Vector3(
(p_mass / 3.0) * (ly * ly + lz * lz),
(p_mass / 3.0) * (lx * lx + lz * lz),
(p_mass / 3.0) * (lx * lx + ly * ly));
```
where the final line includes both the x and y extents.
However, for CapsuleShape3D, CylinderShape3D, ConvexPolygonShape3D, ConcavePolygonShape3D, and HeightMapShape3D, the final line read `(p_mass / 3.0) * (extents.y * extents.y + extents.y * extents.y)`. I believe this is a mistake, considering the comment in each case mentions using an AABB approximation, which should follow the same approach as BoxShape.
This change corrects the final line to include both the x and y components of the shape's extent.
The angular velocity estimate for kinematic bodies was calculated
incorrectly. Also, fixes its use in some kinematic/rigid collision
calculations.
This fixes#47029.
Helps a lot with soft bodies and generally useful to avoid shapes to go
through the ground in certain cases.
Added an option in ConcavePolygonShape to re-enable backface collision
on specific bodies if needed.
- Fixed SoftBody surface update with new rendering system
- Added GodotPhysics implementation for SoftBody
- Added support to get SoftBody rid to interact with the physics server
- Added support to get SoftBody bounds from the physics server
- Removed support for unused get_vertex_position and get_point_offset
from the physics server
- Removed SoftBody properties that are unused in both Bullet and
GodotPhysics (angular and volume stiffness, pose matching)
- Added RenderingServerHandler interface to PhysicsServer3D so the physics servers don't need to reference the class from SoftBody node directly
Test specific axes before falling back to GJK-EPA algorithm to get more
accurate separation axes for common cases, the same way it's done for
cylinder-cylinder collision.
In the case of falling back to GJK-EPA algorithm to generate cylinder
contact points, margins were never taken into account.
This fixes the depenetration phase for kinematic bodies and allows
consistent floor detection for cylinder shapes.
In 3D, collision is disabled between kinematic/static bodies when
contacts are generated only to report them.
In 2D, this case was already fixed but the code is cleaned to make it
easier to follow.
Fixes#46738 by setting the default inertia to a valid value when there are no valid shapes for a 3d body.
Changed the comment style for the update_inertias method as well.
Joint3DSW instances are also destroyed without explicitly calling free()
for example when changing constrainted bodies at runtime using
set_node method.
- Based on C++11's `atomic`
- Reworked `SafeRefCount` (based on the rewrite by @hpvb)
- Replaced free atomic functions by the new `SafeNumeric<T>`
- Replaced wrong cases of `volatile bool` by the new `SafeFlag`
- Platform-specific implementations no longer needed

-Advanced Settings toggle also hides advanced properties when disabled
-Simplified Advanced Bar (errors were just plain redundant)
-Reorganized rendering quality settings.
-Reorganized miscelaneous settings for clean up.
This change makes test_body_motion more reliable when the kinematic body
recovers from being stuck.
- When recovery occurs, the rest information is generated, in order to
make sure collision results from test_move, move_and_collide and
move_and_slide are consistent and return a collision in case of overlap.
- The new calculation for recovery vector makes sure the recovery is
never more than the overlap depth between shapes.
This can help with cases where the kinematic body overlaps with several
shapes.
Recovery is made iteratively, without forcing a full overlap at each
step. This helps with getting proper rest information when recovery
occurs.
- One Way Collision:
When attempting motion, contact direction is checked against motion
before skipping in order to solve cases where kinematic bodies can sink
into one-way collision shapes.
Rest info now sets max contact depth in order to properly handle one-way
collision.
- Low speed motion is now handled in the rest info, by never setting
min_allowed_depth lower than motion length.
Separation is always applied with full margin, otherwise contact is lost
when low speed motion occurs right after higher speed motion.
- Similar changes are applied to 3D in order to make 2D and 3D
consistent.
Cylinder contact points generation is adjusted to make it more stable
when standing on triangle meshes.
Point-Circle:
Switched to simpler plane projection as it's done for Point-Face contact
points. It solves some cases where discrepancies between the two points
caused the cylinder to jump.
Edge-Circle:
Same as before, the case for edge has just been moved from Face-Circle
to a specific method.
Face-Circle:
The previous method was clipping edges against the circle, and then
tried to add contact points when there wasn't enough support and failed
in some cases.
Now using a different algorithm which adds proper contact points around
the circle more consistently.
First, by clipping edges against circle segments using Face-Face
algorithm.
Second, by clipping edges against the circle plane.
Cylinder collision detection uses a mix of SAT and GJKEPA.
GJKEPA is used to find the best separation axis in cases where finding
it analytically is too complex.
Changes in SAT solver:
Added support for generating separation axes for cylinder shape.
Added support for generating contact points with circle feature.
Changes in GJKEPA solver:
Updated from latest Bullet version which includes EPA fixes in some
scenarios.
Setting a lower EPA_ACCURACY to fix accuracy problems with cylinder vs.
cylinder in some cases.
-Rendering server now uses a split RID allocate/initialize internally, this allows generating RIDs immediately but initialization to happen later on the proper thread (as rendering APIs generally requiere to call on the right thread).
-RenderingServerWrapMT is no more, multithreading is done in RenderingServerDefault.
-Some functions like texture or mesh creation, when renderer supports it, can register and return immediately (so no waiting for server API to flush, and saving staging and command buffer memory).
-3D physics server changed to be made multithread friendly.
-Added PhysicsServer3DWrapMT to use 3D physics server from multiple threads.
-Disablet Bullet (too much effort to make multithread friendly, this needs to be fixed eventually).
This change allows collide_shape, intersect_shape, cast_motion and
rest_info in both 2D and 3D to ignore disabled shapes and make them
consistent with the physics simulation.
In some other cases, _cull_aabb_for_body is used and filters shapes out
internally, but whenever a physics query uses the broadphase directly
without calling _cull_aabb_for_body, disabled shapes can be returned
and need to be filtered out.
Inverted the spotlight angle attenuation so a higher value results in
a dimmer light, this makes it more consistent with the distance
attenuation.
Also changed the way spotlighs are computed in SDFGI
and GIPorbes and GPU lightmapper, now it matches the falloff used in the scene rendering
code.
-Always use temporal reproject, it just loos way better than any other filter.
-By always using termporal reproject, the shadowmap reduction can be done away with, massively improving performance.
-Disadvantage of temporal reproject is update latency so..
-Made sure a gaussian filter runs in XY after fog, this allows to keep stability and lower latency.
-Added more finegrained control in RenderingDevice API
-Optimized barriers (use less ones for thee same)
-General optimizations
-Shadows render all together unbarriered
-GI can render together with shadows.
-SDFGI can render together with depth-preoass.
-General fixes
-Added GPU detection
AudioEffectCapture allows access to the microphone and other audio on an audio bus in real-time.

Channels that are inactive -or when playback has not started yet- will report -200 dB as their peak value (which is also the lowest value possible during playback).
- Based on C++11's `thread` and `thread_local`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed (except for the few cases of non-portable functions)
- Simpler for `NO_THREADS`
- Thread ids are now the same across platforms (main is 1; others follow)
- fixes scale values of 0.0013 (det == 0.00004) not rendering, they should render even at small values, but not at zero like the editor grid plugin supplies zero exactly.
- fixes node_3d_editor_plugin visibility bug when scale is zero
- fix culling with small scaling values - which are still valid to be rendered like 0.00004
note: grid is still not fixed, it has det == 0 issues but this fixes one of them.
-Removed sync to draw, now everything syncs to draw by default.
-Fixed many validation layer errors.
-Added support for VkImageViewUsageCreateInfo to fix validation layer warnings.
-Texture, buffer, raster and compute functions now all allow spcifying which barriers will be used.
-When importing, a vertex-only version of the mesh is created.
-This version is used when rendering shadows, and improves performance by reducing bandwidth
-It's automatic, but can optionally be used by users, in case they want to make special versions of geometry for shadow casting.
-All shadow rendering is done with raster now (no compute)
-All shadow rendering is done by rendering directly to the shadow atlas
-Improved how buffer clearing is done to optimize the above.
-Ability to set shadows as 16 bits.
-SDFGI direct light is done over many frames
-SDFGI Changed settings for rays/frame
-SDFGI Misc optimizations
