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?

  According to Carmack, it really wasn't that difficult to program around it, which I'm sure made the decision easier. https://twitter.com/ID_AA_Carmack/status/136614459887202305 https://twitter.com/ID_AA_Carmack/status/136614459887202305 https://twitter.com/ID_AA_Carmack/status/137189212519792640 https://twitter.com/ID_AA_Carmack/status/137189212519792640

  You might find my previous comment about this topic interesting: https://news.ycombinator.com/item?id=4088162 https://news.ycombinator.com/item?id=4088162 Here is the code section that you might find interesting in tr_backend_draw.cpp. The comments start at line 1439: https://github.com/id-Software/DOOM-3-BFG/blob/master/neo/renderer/tr_backend_draw.cpp#L1439 https://github.com/id-Software/DOOM-3-BFG/blob/master/neo/re...

How is the engine for BFG different from the older Doom3 version?

  http://en.wikipedia.org/wiki/Doom_3#Doom_3:_BFG_Edition http://en.wikipedia.org/wiki/Doom_3#Doom_3:_BFG_Edition The BFG Edition features enhanced graphics, better sound with more horror effects, a checkpoint save system, and support for 3D displays and HMDs.

  As far as I can tell, not much except the addition of stereoscopic 3D and various optimisations.
- Jayschwa 14y ago
  I believe some tech from id Tech 5 was back-ported into it. Wikipedia says it also has support for 3D [head-mounted] displays.
  - phoboslab 14y ago
    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) [0] https://github.com/id-Software/DOOM-3-BFG/tree/master/doomclassic/doom https://github.com/id-Software/DOOM-3-BFG/tree/master/doomcl...

  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 14y ago
  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_ 14y ago
  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. http://fabiensanglard.net/doom3/index.php http://fabiensanglard.net/doom3/index.php

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/swf 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.
