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".

Backported from #70885.

lawnjelly d2b1d29634 Physics interpolation - Move out of Scenario
Move VisualServer interpolation data out of Scenario and into VisualServerScene, so the interpolation data and enabled status is now common to all Scenarios.

lawnjelly 3c2df49832 Fix Occluder to properly share resources
In order to properly support the resource sharing paradigm, Occluders are split into Instances and Resources in the VisualServer. Instances are owned by a Scenario, and Resources are global. OccluderShape resources can now correctly be shared by multiple OccluderInstances.

lawnjelly dc14636e68 BVH templated mask checks and generic NUM_TREES
Refactors the BVH to make it more generic and customizable. Instead of hard coding the system of pairable_mask and pairable_type into the BVH, this information is no longer stored internally, and instead the BVH uses callbacks both for determining whether pairs of objects can pair with each other, and for filtering cull / intersection tests.

In addition, instead of hard coding the number of trees, the BVH now supports up to 32 trees, and each object can supply a tree collision mask to determine which trees it can collide against.

This enables the BVH to scale to either the two or 3 trees needed in physics, and the single tree used without pairing in Godot 4 render tree.

lawnjelly 26e93dc5c6 Fix lighting_dirty flag bug
In rare circumstances, changing the geometry data attached to an instance, there was the opporunity for the lighting_dirty flag to get out of sync, which could lead to access to a stale light RID, and warnings or worse.

This PR fixes the problem by ensuring the lighting is always updated on the instance when first adding GeometryData.

Merge pull request #50823 from fbcosentino/3d-material-overlay 2021-11-16 08:21:18 +01:00
Fernando Cosentino cc8846bef6 Added material_overlay property to MeshInstance
Applying overlay materials into multi-surface meshes currently
requires adding a next pass material to all the surfaces, which
might be cumbersome when the material is to be applied to a range
of different geometries. This also makes it not trivial to use
AnimationPlayer to control the material in case of visual effects.
The material_override property is not an option as it works
replacing the active material for the surfaces, not adding a new pass.

This commit adds the material_overlay property to GeometryInstance
(and therefore MeshInstance), having the same reach as
material_override (that is, all surfaces) but adding a new material
pass on top of the active materials, instead of replacing them.

Implemented in rasterizer of both GLES2 and GLES3.

lawnjelly 788f075b44 Portals - Allow user to set roaming expansion margin
Previously a crude metric was used to decide on the roaming expansion margin, but it created unexpected results in some scenarios. Instead this setting is exposed to the user via the RoomManager, allowing them to tailor it to the world size, room sizes, roaming objects sizes and the speeds of movement.

lawnjelly 776623d56b Portals - Improve UI and add shortcuts
This PR makes the 'convert rooms' button permanently on the toolbar and accessible whichever node is selected, so you can convert rooms without having to select the RoomManager first.

It also adds a togglable item 'view portal culling' to the 'View' menu which is a simple way of setting the RoomManager 'active' setting without the RoomManager being the selected node.

Both of these have keyboard shortcuts, which should make it much faster to reconvert rooms and edit.

In addition there the string in the 'Perspective' Listbox is modified to show [portals active] when portal culling is operational, for visual feedback. This is updated when you change modes, and when the rooms are invalidated.

- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.

lawnjelly a814dda2ae BVH - fix deferred visible mesh collision check
When making items visible from the visual server, the collision check is deferred to prevent two identical collision checks when set_pairable is called shortly after.

It turns out that for some items (especially meshes), set_pairable is never called. This PR detects this occurrence and forces a collision check at the end of the routine.

lawnjelly 00bd087d82 BVH add support for visibility (activation)
A major feature lacking in the octree was proper support for setting visibility / activation. This meant that invisible objects were still causing lots of processing in the tree unnecessarily.

This PR adds proper support for activation, items are temporarily removed from the tree and collision detection when inactive.

lawnjelly 2527067c4d Partially revert change to BVH render tree update method
Leaves in the bug fixes, but reverts the change to the update method.

Turns out the new update method of getting the scenarios was causing problems, I will need to consult with reduz on the best way of getting access to the scenarios for a single update per frame.

Doing multiple updates isn't terrible but it should be nicer to get a single update working, as it should be more efficient, and give a single point for pairing callbacks.

JFonS 112b416056 Implement new CPU lightmapper
Completely re-write the lightmap generation code:
- Follow the general lightmapper code structure from 4.0.
- Use proper path tracing to compute the global illumination.
- Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper)
- Use OpenImageDenoiser to improve the generated lightmaps.
- Take into account alpha transparency in material textures.
- Allow baking environment lighting.
- Add bicubic lightmap filtering.

There is some minor compatibility breakage in some properties and methods
in BakedLightmap, but lightmaps generated in previous engine versions
should work fine out of the box.

The scene importer has been changed to generate `.unwrap_cache` files
next to the imported scene files. These files *SHOULD* be added to any
version control system as they guarantee there won't be differences when
re-importing the scene from other OSes or engine versions.

This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress;
Was then finished and polished by me on my free time.

Update copyright statements to 2021
Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

lawnjelly 667c970b77 Optimize octree and fix octree leak
Prevents adding new octants until a limiting number of elements have been added to the current octant. This enables balancing the benefits of brute force against the benefits of spatial partitioning. The limit can be set per octree.

Project settings are added for rendering octree to set the best balance per project depending on number of tests per frame / tick, and the amount of editing of the octree.

Fixes octants being leaked when removing elements.

Optimize octree with cached linear lists

Storing elements in octants using linked lists is efficient for housekeeping but very slow for testing. This optimization stores additional local_vectors with Element pointers and AABBs which are cached and only updated when a dirty flag is set on the octant.

This is selectable with 2 versions of Octree : Octree and Octree_CL, Octree being the old behaviour. At present the cached list version is only used for the visual server octree (rendering) as it has only been demonstrated to be faster there so far.

This uses slightly more memory (probably a few kb in most cases) but can be significantly faster during testing (culling etc).

Change "ID" to lowercase "id"
Reasoning: ID is not an acronym, it is simply short for identification, so it logically should not be capitalized. But even if it was an acronym, other acronyms in Godot are not capitalized, like p_rid, p_ip, and p_json.
