lawnjelly 0a350845d5 BVH - fix stale current_tree in deactivate function
Changes passing of current_tree from a member variable to a function argument, making bugs due to stale state less likely.

Fix a bug in deactivate where current_tree variable was stale. This may have resulted in visual anomalies.

PouleyKetchoupp 0dacc681b6 Fixed unnecessary bvh tree updates when calling set_pairable
Dynamic BVH doesn't update the tree anymore when calling set_pairable
with no parameter change.

Also modified Godot Physics broadphase to create objects directly with
pairable (static) set correctly to make use of this optimization for the
BVH broadphase.

Note: Octree broadphase doesn't use this optimization because it forces
an update on move, so passing the proper AABB and static parameters on
creation would cause the tree to update twice.

Core: Drop custom `copymem`/`zeromem` defines
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.

There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

Backport of #48239.

Fix area calculation of Face3
There seemed to be a bug in area calculation in Face3::get_area()-function. It returned the area of "imaginary" parallelogram instead of the triangle. Therefore the area returned was twice the real area. This manifested itself when using a hydro module for godot ( https://gitlab.com/ringtechsolutions/godot-tools/hydro/hydro ) causing the buoyancy to be two times the expected value.

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.

GDScript: Clarified/fixed inaccuracies in the built-in function docs.
The input to smoothstep is not actually a weight, and the decscription
of smoothstep was pretty hard to understand and easy to misinterpret.

Clarified what it means to be approximately equal.

nearest_po2 does not do what the descriptions says it does. For one,
it returns the same power if the input is a power of 2. Second, it
returns 0 if the input is negative or 0, while the smallest possible
integral power of 2 actually is 1 (2^0 = 1). Due to the implementation
and how it is used in a lot of places, it does not seem wise to change
such a core function however, and I decided it is better to alter the
description of the built-in.

Added a few examples/clarifications/edge-cases.

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 df18f72384 BVH fix pairing AABB init and mask checks

lawnjelly ba5e4d8baa BVH fix stale changed items, causing dangling pairs
In the octree collisions are flushed as objects are moved, whereas in the BVH they are usually flushed once per frame.

This was causing problems in the render tree in some rare situations where objects were being created (perhaps deleted and recreated using the same handle in the same frame). This PR flushes the collisions before creating objects, and set_pairable.

set_pairable may not be necessary but it is done for safety until proven not necessary.

Also a small potential for a bug is closed in remove_unordered use.

lawnjelly a241aeb289 Fix BVH set_pairable and masks.
Calling set_pairable now will update collisions (rather than waiting for the next item_move).

Mask behaviour used for pairing now (hopefully) matches octree.

JFonS 7d7d7ef16d CPU lightmapper formatting and minor fixes. 2021-01-14 18:08:33 +01:00
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 🎆

Andrii Doroshenko (Xrayez) 47899e67c5 Add ability to restore `RandomNumberGenerator` state
3.2 version of b5107715f1.

`get_seed()` still returns the previous state and not the initial seed,
because users may rely on this behavior for resetting the state in 3.2.
Documented this is going to be fixed in 4.0.
