bean-mhm/realbloom

📋 Changes

• Now using [grace v1.2](https://github.com/bean-mhm/grace/releases/tag/v1.2)

📋 Changes

• Fixed bug where using unexpected locale or region settings (for example, using `,` for decimal point and/or `.` for thousands separator) would mess up some parts of the program including parsing the CMF tables which would ruin dispersion.

📦 Diffraction

• The output is now perfectly centered and sharp due to forcing odd resolutions (example: 501x517).
• Now defaults to linear normalization for more realistic results. Logarithmic normalization can be optionally enabled.
• Removed the *Aperture* slot. *Diffraction Input* and *Diffraction Result* should be used instead.
• The output no longer goes into the *Dispersion Input* slot. You can use the new *Move To* button in the *Image Slots* panel to move the contents of *Diffraction Result* into *Dispersion Input*.

📦 Dispersion

• Now using proper logarithmic scaling.
• The new *Edge Offset* parameter defines whether to scale inward, outward, or in between.

📦 Convolution

• The *FFT CPU* method now supports deconvolution (experimental).
• Renamed the *LAYERS* section to *BLENDING*.
• Minor improvements

📦 Image Transforms

• 

📦 Color Management

• Now using [grace](https://github.com/bean-mhm/grace) as the default user config and the internal config.
• Minor improvements
• 

📦 Drag 'n Drop

• You can finally drag and drop an image file into the main window to load the contents into the selected slot.

📦 UI Layout

• Added a *Move To* button in *Image Slots* for moving the contents of one slot to another.
• Added a *Clear* button in *Image Viewer* for clearing and resetting the contents of the selected slot.
• All modules are now in separate tabs/panels.
• Minor layout changes and improvements

📦 CLI

• New command `image-transform` was added to apply an *Image Transform* to any arbitrary image file.
• Updated the arguments according to the new features and options added in different modules.

📦 Code

• Many loops have been accelerated using OpenMP parallelization.
• Fixed invalid includes for OCIO and OIIO, the code no longer includes the sources and binaries for these libraries. The *How To Build* section in `README.md` now explains how to install and use vcpkg for linking with said libraries.
• Performance improvements, bug fixes, and code cleanups

📦 Color Management

• RealBloom now comes with a custom OCIO config, made by using [Troy Sobotka's new AgX config generator](https://github.com/sobotka/SB2383-Configuration-Generation) and [Eary Chow's version of AgX](https://github.com/EaryChow/AgX/releases/tag/v11.9).

📦 Image IO

• A new *IMAGE IO* section has been added for adjusting image input/output color management settings. The user is no longer prompted to choose a color space when importing/exporting images.
• More output image formats are now supported, including TIFF, PNG, and JPEG. The active view transform is applied to non-linear formats like PNG and JPEG and can be optionally applied to linear images as well.
• Upgraded to [Native File Dialog Extended](https://github.com/btzy/nativefiledialog-extended).

📦 Dispersion

• A GPU method has been implemented, allowing for much faster simulations.

📦 Convolution

• A new experimental GPU FFT method has been added. This method performs poorly as of now and is intended to improve in later releases.
• New *Kernel Color* parameter for colorizing the kernel
• The threshold knee is now transformed exponentially.

📦 Main

• The GUI now requires OpenGL 3.2.
• The main config is now stored in an XML file (`config.xml`).

📦 CLI

• The new CLI provides an interactive way to perform actions. You can enter the CLI by running `realbloom cli`, use `help` to get a list of the supported commands, and exit the program with `quit`. This saves a lot of resources previously used for initializing and cleaning up during repeated tasks such as batch processing a sequence of images.
• The CLI now requires OpenGL 3.2.
• New commands for getting a list of the available `displays`, `views`, and `looks` in the OCIO config
• New output color management and view transform arguments in `diff`, `disp`, `conv`, and `cmf-preview`
• New `--gpu` option in `disp`
• New `--kernel-color` argument in `conv`
• Removed `--compact` in `colorspaces`, it now prints compact output by default, unless `--verbose` is used.
• `demo/Scripts/anim_conv.py` has been updated to work with the new interactive CLI.

📦 More

• Layout improvements
• Improved code quality and structure
• Performance boosts and bug fixes
• Improved state handling in modules
• Better error handling and reporting
• Dispersion color and kernel color are now applied live in preview.
• New *Compare* button for *Dispersion Input* and *Dispersion Result*
• Updated demo images
• + 1 more

📋 Changes

• Color pickers, color buttons, and color tooltips now use the active display/view transform.
• New "Auto-Exposure" option for convolution which helps match the brightness of the convolution output to the input.
• Removed the kernel normalization option.
• File dialog paths are now stored separately for each slot. As an example, if you are continuously opening kernel images from a `Kernels` folder, and aperture images from an `Apertures` folder, the file dialog will store the individual directories for each image slot.
• *Image Viewer* now displays the image source filename.
• New `--compact` option for the `colorspaces` command
• Added a template Python script in `demo/Scripts` for performing convolution on a sequence of frames.
• Minor improvements and bug fixes

📦 FASTER EVERYTHING

• All three modules are now much faster and more optimized.
• New FFT Convolution Method
• ... which is orders of magnitudes faster than previous methods. (Spoiler: GPU FFT Convolution coming soon!)
• Multithreading for Dispersion
• ... allowing for more efficient simulations.
• Now using [PocketFFT](https://github.com/mreineck/pocketfft)
• ... for more overall performance and consistency.

📦 COLOR MANAGEMENT

• RealBloom now supports accurate color management, tone mapping, and more image formats, thanks to utilizing new industry-standard libraries.
• [OpenColorIO](https://opencolorio.org/)
• [OpenImageIO](https://openimageio.org/)
• ... to support a - *very* - wide range of image formats, including OpenEXR.
• Color-Matching Functions
• ... for more accurate Dispersion. You can use and preview any arbitrary CMF table. RealBloom comes with 3 tables by default.

📦 A FRESH LOOK

• The user interface has been redesigned and re-themed for a more modern and comfortable look.

📦 DEMO CONTENT

• New demo content has been added.
• More Apertures
• New "Kernels" Folder
• ... with premade and ready-to-use kernels. Includes a custom gaussian kernel generator.
• Updated HDR Images
• Now using OpenEXR

📦 AND MORE

• Diffraction Pattern can now work with any dimensions and aspect ratio
• Mix mode for blending the convolution result
• Support for non-uniform scaling and cropping of the kernel
• Can now disable kernel normalization
• New sophisticated XYZ conversion system
• More intuitive image slots
• New S-shaped contrast curve
• Bug fixes and performance improvements

📦 WHAT'S PLANNED

• In the next few months, I'll be working to make the current set of features utilize the GPU, for more performance.
• Dispersion on the GPU
• Diffraction Pattern (FFT) on the GPU
• FFT Convolution on the GPU
• Image transforms on the GPU (e.g. kernel scaling)
