Just saw that Fabien Sanglard released his Quake 2 Source Code Review a couple of days ago.

Nice. I could have swore that q2 had software colored lighting, apparently I was wrong. :(

No, but you can have it nowadays... FTEQW software engine does. Possibly DP vid_soft mode also. It would have been nice to see a modern engine added to the comparison- FTEQW, KMQuake2, Berserker, etc. Newbies need to be herded AWAY from the ancient original exe's.

I loved the lookup table trick to implement transparency in software. Very clever.
I know FrikaC made a cgi-bin version of the quakec interpreter once and wrote part of his website in QuakeC :) (LordHavoc)

yeah though lookup alpha is common at the point when quake2 did it (even Heretic did it), even the 33/66% alpha method (using row or column order to switch between the two)

shame it didn't do more than that - there certainly was room for additive transparency with using the colormap fade table to control the opacity of the additive colors.

BTW FTEQW's software engine only does colored lighting on the level in 16/32bit color modes, and doesn't color the models, AND its software renderer is retired, anyway
