2022-08-31Implement Physical Light Units as an optional setting.clayjohn
This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value. In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.

2021-11-19GPULightmapper: better algorithm to generate rays for indirect lightingWilliam Deurwaarder
Previous algorithm used an algorithm to generate rays that was not completely random. This caused artifacts when large lighmap textures were used. The new algorithm creates better rays and by that prevents artifacts.
2021-10-28clang-format: Disable alignment of operands, too unreliableRémi Verschelde
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`.
2021-10-16GPULightmapper: execute dilate also after denoiseWilliam Deurwaarder
Dilate fills gaps that are caused by the rasterization. As dilate is based on the alpha-channel which is not part of denoise, dilate can be run after denoise as well. So that colors are not denoised/mixed over seams.
2021-10-16GPULightmapper: execute dilate before denoiseWilliam Deurwaarder
Dilate fills gaps that are caused by the rasterization. Previously denoise was done before dilate which caused the gaps to become filled (non-zero). This resulted that the gaps were not recognized by dilate and the background color leaked. This is fixed by executing dilate before denoise.
2021-10-15GPULightmapper: increase ray triangle hit rateWilliam Deurwaarder
Currently the method ray_hits_triangle determines triangles not to be hit by a ray due to an epsilon that is too big. In practice those triangles are hit by those rays. This is fixed by introducing a smaller epsilon.

2021-10-12GPULightmapper: prevent loop with max iterationsWilliam Deurwaarder
In case the calculation of the delta contained infinity values (division by zero), than later the calculation of the next cell failed as the infinity value was multiplied by zero which resulted in a nan. The nan-value caused that the next cell was equal to the current cell which resulted in an end-less loop, which only terminates by the maximum iterations protection. This is solved by replacing infinity with grid_size which acts as infinity.
2021-10-12GPULightmapper: process rays to sky in all bounces as activeWilliam Deurwaarder
Before this change only rays to the sky (RAY_MISS) in the first bounce were processed as active rays. This caused artifacts, areas were too light, when more than one bounce were processed. Now rays to the sky are processed as active rays for all bounces.
2021-10-12GPULightmapper: skip smoothen positions for flat trianglesWilliam Deurwaarder
Smoothening positions for flat, non-smoothened, triangles is unnecessary and caused positions to move outside their triangle which caused side-effects as rays from those positions intersected with triangles which could not be reached from the original triangle. This is solved by skipping smoothening of positions for flat triangles. A triangle is determined to be flas as its vertex normals are equal.
2021-09-14GPULightmapper exclude back-face triangles while calculating bouncesWilliam Deurwaarder
Edges that are at the edge of a plane, may get behind the scene and will hit back-face triangles which where included in the lighting calculations. This caused leaking of light at the edge of planes. In case a ray hits back-face triangle, it is skipped in the bounce calculations.
2021-09-11GPULightmapper's triangles and their bounding box will be in-syncWilliam Deurwaarder
Previously the bounding boxes and triangles were maintained in two separate arrays (Vectors). As the triangle vector was sorted and the bounding-box array was not , the order of both arrays differed. This meant that the index in one was different than the other, which caused lookup issues. To prevent this, the bounding-box is now part of the triangle structure so that there is a single structure that cannot become out-of-sync anymore.
2021-07-26Implement Binary Shader Compilationreduz
* Added an extra stage before compiling shader, which is generating a binary blob. * On Vulkan, this allows caching the SPIRV reflection information, which is expensive to parse. * On other (future) RenderingDevices, it allows caching converted binary data, such as DXIL or MSL. This PR makes the shader cache include the reflection information, hence editor startup times are significantly improved. I tested this well and it appears to work, and I added a lot of consistency checks, but because it includes writing and reading binary information, rare bugs may pop up, so be aware. There was not much of a choice for storing the reflection information, given shaders can be a lot, take a lot of space and take time to parse.
2021-07-13Implement the ability to disable classesreduz
* This PR adds the ability to disable classes when building. * For now it's only possible to do this via command like: `scons disable_classes=RayCast2D,Area3D` * Eventually, a proper UI will be implemented to create a build config file to do this at large scale, as well as detect what is used in the project.

2021-05-03Assorted fixes to UV unwrapping and GPU lightmapperjfons
Various fixes to UV2 unwrapping and the GPU lightmapper. Listed here for context in case of git blame/bisect: * Fix UV2 unwrapping on import, also cleaned up the unwrap cache code. * Fix saving of RGBA images in EXR format. * Fixes to the GPU lightmapper: - Added padding between atlas elements, avoids bleeding. - Remove old SDF generation code. - Fix baked attenuation for Omni/Spot lights. - Fix baking of material properties onto UV2 (wireframe was wrongly used before). - Disable statically baked lights for objects that have a lightmap texture to avoid applying the same light twice. - Fix lightmap pairing in RendererSceneCull. - Fix UV2 array generated from `RenderingServer::mesh_surface_get_arrays()`. - Port autoexposure fix for OIDN from 3.x. - Save debug textures as EXR when using floating point format.
2021-04-27Core: Drop custom `copymem`/`zeromem` definesRémi Verschelde
We've been using standard C library functions `memcpy`/`memset` for these since 2016 with 67f65f66391327b2967a20a89c3627e1dd6e84eb. 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.

2021-02-07Invert spotlight angle attenuationjfons
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.
2021-01-26Reorganize RenderingDevice barriersreduz
-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.

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 🎆

2020-05-18GLSL: Change shader type specifier from [vertex] to #[vertex]Rémi Verschelde
The added `#` prevents clang-format from misinterpreting the meaning of this statement and thus messing up the formatting of the next lines up until the first `layout` statement. Similarly, a semicolon is now enforced on `versions` defines to prevent clang-format from messing up formatting and putting them all on a single line. Note: In its current state the code will ignore chained statements on a single line separated by a semicolon. Also removed some extraneous lines missed in previous style changes or added by mistake with said changes (e.g. after uniform definitions that clang-format messes up somewhat too, but we live with it).
2020-05-14Style: Enforce separation line between function definitionsRémi Verschelde
I couldn't find a tool that enforces it, so I went the manual route: ``` find -name "thirdparty" -prune \ -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \ -o -name "*.glsl" > files perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files) misc/scripts/fix_style.sh -c ``` This adds a newline after all `}` on the first column, unless they are followed by `#` (typically `#endif`). This leads to having lots of places with two lines between function/class definitions, but clang-format then fixes it as we enforce max one line of separation. This doesn't fix potential occurrences of function definitions which are indented (e.g. for a helper class defined in a .cpp), but it's better than nothing. Also can't be made to run easily on CI/hooks so we'll have to be careful with new code. Part of #33027.
