Changelog

Release Candidate 9 (formats, python bindings, and fixes) [September 2026] [0.4.X]

• TODO: Improve project structure and modularity, currently the code is quite monolithic and could be better organised into separate modules and files for better maintainability and readability.
• TODO: Add support for additional mesh formats such as Neutral (.ntr) files, ANSYS Input (.inp) files, FEBIO 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.

[0.3.0] 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.
• TODO: 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.
