When looking at the classes in [VTK Class List](https://vtk.org/doc/nightly/html/annotated.html)

It would be nice to add in \*\* Detailed Description\*\* an indication as to where the class is in the VTK source.

For example, in the case of [/vtkSubdivideTetra](https://vtk.org/doc/nightly/html/classvtkSubdivideTetra.html#details), in \*\* Detailed Description\*\*:

Change the line:

subdivide one tetrahedron into twelve for every tetra

to:

subdivide one tetrahedron into twelve for every tetra, found in _./Filters/Modeling/_

In 20 years of using VTK I usually do a

```bash
find . -name '*xx.h'

```

and wonder why this information is not on the web page.

I have added this as an issue [Request to add the location of classes in the documentation.](https://gitlab.kitware.com/vtk/vtk/issues/17646)

Good idea. I’ve done the same kind of `find` countless times.

It would also be nice if the VTK module name was spelled out there (e.g. `vtkFiltersModeling` for your example), for easy copy-pasting into `CMakeLists.txt`. I know it’s almost always a concatenation of `vtk`, `Subdirname` and `Subsubdirname`, but it would be nice to have it presented.

@estan That’s a good idea, @ben.boeckel also mentioned this in the above issue. These should be simple enhancements to the documentation.
