Implementation of the CJFIT algorithm as a Blender Add-on.

The current implementation uses iterative roto-translation with fixed step size to remove intersections.

Requires Blender >= 4.2

Normal procedure for installing an extension from disk.
From within Blender: Edit -> Preferences -> Get Extensions -> (top right dropdown arrow) -> Install from disk -> (select the release zip for your os)

Once installed you will see the extension's panel in the Sidebar of the 3D Viewport:

You can adjust the cylinder's radius and height.
A cylinder is created in the viewport to visualize the changes in real time.
You can hide/delete the cylinder from the Outliner:

When a Mesh object is selected and active, the Test button activates.
Clicking Test, well, initiates the test.
The test is blocking because, as of now, it runs on the draw thread.
You will, however, visualize the rotation/adjustments of the object in realtime, as the algorithm tries to solve the problem.

When the test finishes, the original object will be parented to its convex hull, parented to its bounding box:

A notification will appear with the test result:

The object will be in the solving orientation and position:

Or in case of a negative outcome, like:

the object will be in the last orientation and position where the algorithm concluded the object does not fit.
