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.
2021-09-11GPULightmapper'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.
2021-05-03Assorted 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.
2021-02-07Invert 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.
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.
2020-05-10New lightmapperJuan Linietsky
-Added LocalVector (needed it) -Added stb_rect_pack (It's pretty cool, we could probably use it for other stuff too) -Fixes and changes all around the place -Added library for 128 bits fixed point (required for Delaunay3D)
