Hi Andy,

> On a side note what does the add detail to inflections do?

It analyzes surface fragments to see if they have a kind of "S" type shape where curvature is changing from one side to another (that's an inflection point), and breaks those down with more triangles.

Those kinds of areas tend to create some pretty noticeable display shading artifacts if they don't get refined enough. There was a recent example here:

In the future I'd like to try and manage the display density more automatically, something like start with a coarse mesh initially and then in the background calculate higher density ones if there is plenty of memory available.
