Strutt your stuff! / RBDoom3-BFG VR experiement
July 17, 2016, 03:06:15 PM
Hey guys, just thought I'd pop in with a little mod I'm working on for RBDoom3, mainly fixing up some of the VR leftovers.

I have yet seen an actual working port to SteamVR/OpenVR just yet so I have done just that, started from scratch using Robert's base class he put up in a separate branch years ago.

It's not quite complete, but it's functional. Works with my old DK2. I'm interested in getting the bugs worked out so maybe I can do a pull request someday soon.
For now its Windows-only.

Probably vomit inducing, but I'm not 100% sure I have the FOV or Projection matrix correct.

id Tech 4 Engine Coding / Deferred Shading
August 27, 2014, 11:09:13 PM
Hey all,

I have yet to see anyone do any real work on optimizing the original Doom 3's renderer for modern systems. I have set out to do just that.

I forked dhwem3 on GitHub: https://github.com/raynorpat/dhewm3. It uses a subset of Tr3B's BFG framebuffer code as well.
Pics are over here of the gbuffer construction: http://imgur.com/a/gkTMW

It's still a WIP. Forward Shading is broken and the deferred lighting suffers from a lack of attenuation and shadows of course.
