Original Quake using Doom 3 Technology

tc writes "Charles Hollemeersch is currently developing a source port for the original Quake that adds "stencil shadows". Stencil shadows are extremely detailed and realistic. The results are very impressive. The code is apparently based on the same algorithms used in Doom 3." Sure makes me wish Quake looked this good the first time around, but I reckon my computer wouldn't have been able to render it fast enough to play it, either.
