Changelog

Release Candidate 9 (first public release, formats, python bindings, and fixes) [July - September 2026] [0.3.X - 0.4.X]

• TODO: Improve project structure and modularity.
• TODO: Add support for additional mesh formats such as Neutral (.ntr) files, ANSYS Input (.inp) files, and MARCs files.
• TODO: Python bindings using PyO3 for drop-in replacement in existing Python workflows.

[0.3.X]

• TODO: Fix the CLI and TOML export of images.
• TODO: HTML performance improvements.
• TODO: Cannot visualise files that have unsupported element types in them.
• TODO: Test bonemat and luma at same integration value to see if that is the source of difference.
• TODO: Workout a better way to handle the SVG export of large models so that there are issues with OOM errors.
• TODO: Workout a method that produces leaner SVG files that don’t have occluded geometry in them, which is currently a limitation of the SVG export.
• TODO: Look at how the abaqus sets are defined and the part definitions, setting global as part name from mesh/mod.rs is probably not the best approach.
• TODO: Improve the phantom calibration tool, currently it is a bit clunky and could be improved to be more user-friendly and intuitive.

[0.3.7]

• Add cylindrical ROI and node based box ROI phantom calibration.

[0.3.6]

• Added the histogram export functionality to visualisation of already assigned models.
• Unified timestamps on any exports from visualisation to use the same UTC timestamp format.
• Mesh filenames are now parsed to the visualisation so when exporting images, the mesh filename is used in the export filename, making it easier to identify the source of the exported images.

[0.3.5]

• Fix the TOML output that had slope and intercept values swapped, which is a bit of a silly mistake to make and has been fixed.

[0.3.4]

• New ROIs now spawn in the centre of the CT planes, with a fall back to the old arbitrary fixed location.
• Corrected TOML ROI output to avoid dividing a string, which could break formatting in the output file.

[0.3.3]

• Fix for the TOML output to be in the right units for LUMA material assignment.
• Now only a CT is needed to load in to the mesh CT viewer, making phantom calibration easier.

[0.3.2]

• Fix fragility in ANSYS node reading that caused failures in unaccounted for string patterns.
• Fix handling of unsigned char and signed char scalar types in VTK files.

[0.3.1]

• Change the sliders value to use an input (spinbox) so that slices can more precisely be stepped through.
• Updated to the 0.7.0-rc2 of vtkio to resolve possible lz4 vulnerabilities.

[0.3.0] First Public Release

• Refactored the mesh code to make the abaqus file easier to manage.
• Refactored the volume code into separate modules to make it easier to manage and maintain.
• Expanded scan format support (NIfTI and NRRD).
• Clippy lint fixes and code refactoring to improve code quality and maintainability.
• Frontend cleanup and fixes.
• Changed abaqus files to not set part names to global, for single part files.
• Support FeBIO files.
• Phantom Calibration tool built in to the GUI.
• Clean up the codebase, remove unused code and dependencies, and improve documentation for better maintainability and usability.

Release Candidate 8 (enhancement, features, and fixes) [May/June 2026] [0.2.0 - 0.2.5]

[0.2.5]

• Moved from JSON serialised IPC to Tauri raw IPC to improve visualisation performance.
• Made improvements to the RAM usage of the visualisation GUI, by using the built-in clipping planes in Three.js and better material use.
• Rotation in the visualisation window was originally setup with Three.js OrbitControls, which have a fundamental limitation on the rotation of the camera around the target point. This has been replaced with ArcballControls, which allows for a more natural and unrestricted rotation of the camera around the target point.
• Updated to use the latest version of Three.js (r185).
• Added the Three.js ViewHelper to the visualisation window, which allows for a better understanding of the orientation of the model in 3D space.
• Moved to HUGO for documentation, which allows for better organisation and navigation of the documentation, as well as better support for versioning and multilingual content.

[0.2.4]

• Some code refactoring and output clarity, printing the luma version used in generated files to create repeatablity.
• Visualisation is now a single consolidated command with granular control through subcommands.
• Added support for VTK file type import and export.
• New fix attempt for number of materials.
• Increased accuracy of abaqus inp file.
• Added density back calculation to the inp files.

[0.2.3]

• Fixed number of materials not matching the value set in the config.
• Fixed issue when using dicom files, where a double correction was being applied and skewing the outputted.
• Fix resizing of the CT image appears to break LUMA until it is returned to its original size/CT images don’t resize and move with the window.

[0.2.2]

• Fix visualisation for abaqus files.
• Fix scanIP generated abaqus files.
• Add the mean value to the histogram.
• Improve the mesh + CT view. It looked bad and cluttered in comparison to the normal visualisation view.
• Consolidated the html viewer to be a single file correctly called in tauri.
• CT image picking from dicom stack.
• Better DICOM image support.

[0.2.1]

• Consolidate into one build type, don’t need to separate feature builds for visualisation and non-visualisation, just have the visualisation features be optional and not used if not needed.
• Some minor fixes to visualisation performance (see known issues).
• Ported from tiny_http to Tauri v2 to mitigate issues with visualisation (this presents the opportunity for a full GUI in the future alongside the CLI).

[0.2.0]

• Moved from legacy key=value parameter file format to structured TOML format for better readability and validation.
• Added the choice to use either a gap value or a fixed number of materials for material grouping, providing more flexibility in material assignment strategies.
• Histogram export functionality added, giving a csv and json file with the distribution of materials, with one command.
• Histogram view added to the visualisation page, with extensive options, and the ability to export the histogram as an image.
• Control over the visualisation histogram, such as the number of bins, the range, and the scale (linear or logarithmic).
• More control over visualisation page.
• Can now right-click save image (material distribution and colorbar) on the visualisation page to export the current view as an image (png and svg).
• Updated to use the latest version of THREE.js (r184).
• Migrated from THREE.js WebGL to WebGPU.
• Allow users to visualise models that have already been processed with material assignments, without needing to re-run the assignment process. This would allow users to quickly check the material distribution on their models without needing to wait for the assignment process to complete again.

Release Candidate 1 - 7 (stability and core features) [October 2025] [0.1.X]

• Initial releases with core functionality and visualisation features.
• Used to test and refine against other workflows and users that may be interested in using the tool.
