This is absolutely amazing. I seem to recall ultima underworld came out a few months before with a similar ray tracing engine, but it wasn’t open sourced so it’

Wolf3D has a much more limited renderer - only walls are rendered, no lighting (the shaded side for walls is actually different textures) and the viewport is fixed at the middle of the walls for example. On the other hand Wolf3D was much faster and responsive and had a larger render window than UU. UU itself was not open sourced, however System Shock 1 which is based on the same engine was[0][1].
