Graphics3D not rendering Ball as a filled object
I suppose this is a minor bug. I say "minor" because I think Ball
was introduced as part of the geometric region functionality that's really meant to support the FEM framework and it works well in that context. Thus, we can use it to visualize a sold ball like so:
DiscretizeRegion[Ball[], {{0, 1}, {0, 1}, {0, 1}}]
This is a bug. I reported the problem to Wolfram tech support and I got the following confirmation:
I have filed a bug report with the development team and thank you very much for giving us feedback.
