Andras Lasso

Thanks a lot. It gives perfect results for the meshes submitted in #39. For the meshes submitted in this issue it is much better: - subtracting fibula.vtk from guide.vtk now...

Sounds great, thank you for all your help.

Thanks for investigating this. What do you mean by "boundary edge" and what is the problem with them? It is fine if vtkbool has certain requirements for the input meshes...

OK, thans for the clarification. I'll check if vtkFeatureEdges can correctly detect this edge and if we can fix this by removing the edge and fill holes.

## Linear transforms I would not recommend to introduce separate transform types for `affine`, `rigid`, `axis_permutation`, etc, just a simple linear transformation, described with a homogeneous transformation matrix (4x4; or...

Getting the scale from the transformation matrix is very simple (scale[i] is `np.linalg.norm()` of the i-th column of the transformation matrix). The ngff library can also provide convenience functions for...

In 3D Slicer, each non-overlapping group of segments is stored in a 3D volume (we call this a "layer", I think it is referred to as "channel" above). If all...

I cannot comment on what is common in computer vision, but in medical imaging labelmap volume is the standard (3D volume with char or short voxel value specifying what structure...

> @lassoan For sure. This was the common structure in computer vision too. But this changed, like everything else in the past decade, when learned-based methods became standard. Think about...
