Any '3D' scene on a monitor is an illusion of 3D not true 3D. There were many many 3D games and applications long before the invention of 3D graphical accelerators, these by your definition would not be true 3D...
So I guess Elite, Starglider, Carrier Command, Midwinter, Tomb Raider, Duke Nukem, Doom, 3D Studio, etc etc are not 3D?
