I think it's really interesting that the implementation of Carmack's Reverse is intentionally left out of the source code release. Is this a lingering effect of the patent bullshit Creative Labs pulled back in the day with the original Doom 3?

How is the engine for BFG different from the older Doom3 version?
shocks
As far as I can tell, not much except the addition of stereoscopic 3D and various optimisations.

I believe some tech from id Tech 5 was back-ported into it. Wikipedia says it also has support for 3D [head-mounted] displays.

Yep. John Carmack stated that the BFG edition is actually Doom 3 in the Rage "framework". E.g. Rage's network layer and (probably?) all the behind the scenes stuff like input and file management, boilerplate for different GPUs etc.

Not that we don't have enough of them already, but this release comes with a new port of the Doom1/2 engine as well[0]. I don't know either codebase enough to say what's different, but it's now C++ vs. the original's C[1], and appears to be some Xbox and PS3-specific code as well (not that it's useful to mere mortals)

But with all the stuff ripped out of DOOM and DOOM2 then my original 3.5" floppies might be worth something one day.

If they still work...

Don't see how this re-release would have much effect on their value, given that the original games themselves have been "preserved" by many countless times over across the Internet, likely since Doom's launch. Not to say the disks are any less of a collector's item.
talmand
I was thinking that as the "new" versions make their way into the market the original versions might be harder to come by. But I agree, it's more about the physical disks with labeling than the content. I wish I still had the boxes.

I wonder what's comming up next as the new game industry standard programming language after C++?

People like, John Carmack have 'personally' invested a lot in C++ (with DX and GL)

It appears to contain support for the Oculus Rift VR headset. http://www.oculusvr.com/

John added Rift support to Doom3 BFG and it was the primary demo when the Rift was displayed at E3 and subsequent (kickstarter) tours.

Where is this code that implements the Oculus support?

People named the obvious things, but from doomwiki[0] I noted those:

    > * Flashlight-projected character shadows are disabled.
    > * More light sources in the levels.
The latter may make the game a bit prettier, but the first one was one of the few things that made Doom III stand apart, and might be a letdown.

You can feel the pain :-)

Seems that code existed in Doom before this... although the I_PrintfE appears to be new? Part of the "Rage" framework perhaps? Can anyone comment on this?

Too bad all the commit history got squashed into one single commit. `git blame` can make it entertaining to see the history of where these types of lines come from :-)

So I'm a cheapskate and don't want to bother with the BFG edition. Can I compile this and use the data off the original Doom3 / Resurrection of Evil CDs I have lying in a box somewhere?
ConstantineXVI
Right now: doubt it, but couldn't hurt to try if you've already got the proper environment to compile it anyway. Give it a few weeks and I'm sure someone will "port" it (if nothing else, likely for Doom3 mod compatibility).
voltagex_
By the look of it, no, but I'll have to check the source more later.

You could try watching the price of the BFG edition in the upcoming Steam Winter sale.

One of my favorite things about these id source releases is getting to read Fabien Sanglard's excellent code review that inevitably follows. Here's the review of the idTech4 Doom 3 code released last November.

Is there a chance someone will port this to a Mac buildable? Or are there too many Win/VS dependencies to make this feasible?

What's this?

https://github.com/id-Software/DOOM-3-BFG/tree/master/neo/sw...

A whole SWF-parser/player/renderer? Like Scaleform? Seems to have no ActionScript implementation.

Does anybody know more about this? How complete is it and what features of flash does it play?

It's remarkable that ID software created such a clean nice game engine and holds all the IP without integrating other components: The whole physics engine is also in there and had even been open sourced very early as part of the Doom 3 sdk.
