I've put together my first script. It's
intended to create some specialized
terrain for me. I create an NxN mesh
by determining the [x,y,z] positions
of the vertices. When I'm done I create
faces connecting the vertices. I do
an update method when finished.
I get a nifty little mesh, but it's
invisible in all the viewports but
the perspective view. If I go into
sub object mode and select faces
they show, but not out of that mode.
I'll attach a small copy of the output
