This demo begins with a demo image. The details of how this image is generated aren't important, but it creates a tuneable number of spheres in random positions within a
(100,100,100)image (aka RandomAccessibleInterval).
We then display this image as a volume in sciview
Now comes a key step, we perform what is called a "Connected Components Analysis" (aka CCA), which assigns all connected pixels to a specific label. Each of these labels represents a segmentation.
Note one nuance of this is that if 2 of our randomly generated spheres overlap, they will be treated as being connected.
An alternative would have been to use the pixel values of the image to create each
LabelRegion. However, in practice that is not a luxury that an image analyst has.
The next thing to do is to create meshes for each segmentation label that we have created. We do this by looping over all
LabelRegions that we've created and computing a mesh.
