This refactors the SDF Effects to use a normal blend function instead of doing the blend in the effect itself, improving quality and reducing problematic sampling issues. In addition to this, the effect files have been cleaned up slightly and renamed to their proper names. Glow and Stroke are now supported, which solves both #2 and #4 in one go.
The caching optimization has also now been implemented, reducing the number of renders for this filter to 1 for each tick.
The number of files in the source directory was a little bit much and just made file naming more complex than it had to be. Therefore all files were moved into subdirectories where it matters.
Filters now reside in source/filters/, Sources in source/sources/, OBS Wrappers in obs/, OBS GS Wrappers in obs/gs/, Transitions will reside in source/transitions, Graphics Helpers will be in gfx/.
The nature of this Signed Distance Field based Filter is not to only draw shadows, but to also draw an outline or even glow around a source. Therefore the name "Inner/Outer Shadow (SDF)" does not fit well with the intent of the actual Filter.
Allows for enumerating any kind of source, as long as it has a name and is not private. As obs_enum_scenes is a 23.x and above function, this class should be used instead to remain backwards compatible.
While Linux was not an original goal of the project, it should still be supported out of the box. Therefore a number of changes are contained in this changeset:
- All C++ .h files were renamed to .hpp.
- All C includes (<....h>) were replaced with C++ includes (<c...>) and missing includes were added.
- std::memset and std::memcpy was replaced with memset and memcpy.
- All anonymous structs were removed where necessary.
- `extern "C"` was removed where it wasn't needed.
- #pragma warning was placed behind an #ifdef _MSC_VER
- The macros for `min`, `max` and `clamp` were removed as they were not used.
- `-fpedantic` was added to the GCC flags for bitmask support.
- `gs::rendertarget_op` is now declared before use.
- std::exception(const char*) was replaced with std::runtime_error(const char*).
- Added aligned_alloc and aligned_free macros for GCC and MSVC support.
- Replaced use of `sprintf_s` with `snprintf`.
- Placed additional guards around windows only code.
Additonally some changes were made that do not affect Linux:
- `NOMINMAX` and `NOINOUT` were removed.
Fixes: #27Fixes: #13
Linear Box Blur abuses the fact that with Linear Sampling we can sample up to four adjacent texels at the same time and get a correct result for Box Blur back. Using this the total number of sample for Box Blur is reduced by n, making the total either n+1 (Even Radius) or n (Odd Radius).
Additionally all blur effect files have been merged into a single blur.effect file to reduce the time required to change a single parameter name. New blur effects should be added as a new technique instead of as a new effect file.

Adds Inner/Outer Shadows for dynamic sources based on signed distance field generation. This is fast, but does add a bit of latency when it comes to updates - which means that moving objects will leave a trail before the generator has a chance to update.
Fixes#3
* Supports region, feathered region, inverted region, inverted feathered region and image input.
* Interpolates between image_blur and image_orig depending on the result of the mask function.
This class is an attempt at adding dynamic mipmapping support to OBS, which is lacking this feature. It is pretty much a hack until I figure out how to do it for both d3d11 and opengl and can make a PR for obs-studio to include this ability by default.
This includes support for included, referenced, packaged and downloaded obs-studio libraries, cppcheck, packaging using cpack, 7z, zip or InnoSetup and more.
Standalone builds should not assume that everything is Windows and in the future hopefully work out of the box for Linux and MacOS. This is required if CI should also work for Linux and MacOS.
Related: #13
* Standalone builds no longer require you to have a compiled version of OBS Studio. Instead the project will now download the last compatible libOBS version from CI and use it for linking.
* The project version now has a tweak field again, which is either 0 or determined by the number of git commits since the last release tag.
* The Install command now properly uses CMAKE_INSTALL_PREFIX instead of INSTALL_DIR.
* Packaging is now done using CPack instead of custom commands.
This utility class is used to quickly render and retrieve a Texture from a source. It should be used in place of manual rendering since it can be updated quickly, fixing outstanding issue in all places of the plugin instead of just one.
### Plugin
- Shipped files should now be actual images instead of broken images.
### Source Mirror
- Fixed a memory leak caused by not releasing the mirrored source.
- Fixed a rendering slowdown caused by trying to render the source inside an effect loop.
- Fixed 'Point' scaling not actually using the correct sampling.
- Implemented an option for Source Mirror to keep the original size even if rescaling.
Custom Shader allows you to write your own effect files and just have them applied to your source(s). It will dynamically update the properties to match the parameters in the source as well as offer some special parameters to the shader.

- Switched all filters and sources over to new initialization code.
- Fixed a 32-bit crash on machines with CPUs capable of SSE caused by Vertex Buffers.
- Reduced memory requirements of Vertex Buffers by ~60%.
- Removed a superfluous reallocation, loop and copy from Vertex Buffers.
This unifies the logic in GS::IndexBuffer and GS::VertexBuffer so that both can take the same amount of vertices. Additionally the limit for vertices was increased to 16777216 from 65536 to allow for proper models to be stored.
- Improved initialization code to ease future development.
- Fixed several possible crashes in the GS subsystem wrappers.
- Fixed 'Blur' filter color being wrong due to non-power-of-two textures.
- Improved 'Blur' filter error reporting for better debugging and support.
- Fixed 'Blur' filter crashing OBS on GPU reset, better support for this is added in a future version of OBS.
- Fixed 'Blur' filter occasionally just not working.
- Added 'Source Mirror' source which allows you to add filters to a source without modifying it as well as rescaling it.
The source allows you to apply effects to the same source without requiring a new instance of the source. Any changes done to the original source also apply to the mirror, so there is less total work that needs to be done.
It can also rescale the source, allowing you to use the same source as a cheap instant backdrop with Blur for example. What you do in the end is completely unwritten and up to you to decide.
INSTALL would incorrectly copy /data instead of the content of /data, resulting in the plugin not being able to load effects and default images.
PACKAGE was running from the wrong directory, resulting in an extra ".." directory being added, which was invisible for some decompression software.
- Improved cmake script to allow packaging from within the IDE.
- Fixed a crash/freeze caused by not closing the rendering context.
Blur Filter:
- Reduced blur CPU usage and GPU usage.
- Fixed LOD being calculated causing slower rendering.
- Fixed an issue where the effect would randomly not load depending on the actions before starting obs.
- Improved rendering speed via pre-calculated Blur Kernel for those filters supporting it.
- Added 'Color Format' option to improve de-noise type blur for cameras.
- Added 'Bilateral Blur', a de-noise type blur which can be used to reduce low frequency noise.
- Changed default blur size to 5 pixels.
- Improved effect loading to only compile the shader once instead of every time.
Transform Filter:
- Added shearing support allowing for more weird shapes to be rendered.
- Fixed camera aspect ratio when source width is smaller than source height.
- Fixed scaling being affected by rotation.
- Fixed an issue with the mesh reconstruction logic causing invisible sources.
Displace Filter:
This is not very optimized at the moment and will take quite a bit of GPU time. Will have to spend some time later to optimize it and perhaps add directional blur ("Motion Blur" to it).
* Fixed the perspective mesh not filling the entire frame with the default settings.
* Changed the maximum range of 'Field of View' to 179 degrees instead of 180 degrees.
* Changed the direction the perspective camera looks at to +Z instead of -Z. This should feel more natural for users of other 3D programs.
* Changed the 'Position (Z)' default to 0.
* Added translation strings for 'Field Of View', 'Position', 'Scale' and 'Rotation'.
