At one time 3D cards were an add-on. 3D cards did only 3D, so you needed a 2D card. The 3D cards acted as a pass through and only funtioned when programs that were written for them were run. The original Voodoo boards were very popular. Games were written specificly to run on these boards in something called GLIDE. It's like openGL or Direct3D. The deal was you couldn't play many games if you didn't have a Voodoo board.

Voodoo was 3D. Seems like ancient history.
