Part of the problem has been that OpenGL has not had a rich font library.
I’m guessing people have found work arounds? Or has OpenGL improved? Can
we do 3D graphics in a terminal beyond some textronix emulation? A 3D
terminal in the web browser?

Now possible?
Anyone have a version of vim3d? Not exactly a 3D terminal. Great idea
instead of editing a text area, just edit the graphics! Vim SAI?
