XROMM toolkit stands out in the Blender extensions library as a port of the established XROMM Maya Tools, maintained by its own developer, Prof Peter Falkingham, and shipping sample data on GitHub. It has drawn 8694 downloads.
XROMM toolkit is a Blender version of the XROMM Maya Tools, brought to the add-on by Prof Peter Falkingham. XROMM stands for X-ray Reconstruction of Moving Morphology, and the toolkit carries that workflow into Blender rather than Maya. The GitHub releases page ships the add-on together with sample input data you can work through.
The add-on includes a CT marker creator and exporter, imports and exports motion data, and reads files containing NaN values without crashing. It handles frame numbers and multiple objects, and version 0.9.8 added a relative motion function. The add-on can also calculate marker position using an equivalent of vAvg, either by averaging locator vertices, the method the Maya tools used, or by using the bounding box. Vertex averaging may suit highly irregular marker shapes, while the bounding box can be more accurate when vertices are unevenly distributed and should always run faster.
It runs on Blender 4.2 LTS and newer, needs no special permissions, and is released under the GNU General Public License v3.0 or later. At 34.7 KB it installs by drag and drop or from disk.
XROMM toolkit is best for reconstructing moving morphology from X-ray data in Blender and exporting marker motion, following the XROMM workflow without Maya.
XROMM toolkit is completely free to download and use.
XROMM toolkit is compatible with Blender 4.2 LTS and newer, so it targets the current long-term support line rather than older releases. The add-on is a version of the XROMM Maya Tools, rebuilt for Blender by Prof Peter Falkingham, and covers X-ray Reconstruction of Moving Morphology. At 34.7 KB it's a small download. If you're on an earlier Blender build, check the developer's GitHub releases page before installing to confirm which version fits your setup.
XROMM toolkit installs by dragging and dropping the extension into Blender, or by downloading the file and using Install from Disk. It requires no special permissions. The GitHub releases page hosts the latest build along with sample input data you can use to try the workflow. Once it's in place, the tools cover creating and exporting CT markers, importing motion data, and working with frame numbers across multiple objects.
XROMM toolkit is listed as free here, and it's released under the GNU General Public License v3.0 or later. That license governs how you can use, modify and redistribute the add-on. Because licensing terms can change, check the developer's GitHub page for the current details before you rely on it in a project. The same page from Prof Peter Falkingham hosts the download and the sample input data.
XROMM toolkit 0.9.8 added a new relative motion function. The add-on can also calculate marker position using an equivalent of vAvg, either by averaging locator vertices, the method the Maya tools used, or by using the bounding box, which is new. Vertices may be more accurate for highly irregular marker shapes, while the bounding box can be more accurate when vertices are unevenly distributed, and it should always be faster. The developer suggests testing both before committing to an analysis.
