I see this new note on the Adobe Alchemy labs page: "Domain memory (used by Alchemy) and Stage3D hardware acceleration – when used in combination – will be part of a premium tier o…

That reminds me: I noticed that humblebundle.com is apparently involved in the purchase transactions for the recently released 'English Country Tune'. So maybe there's more afoot t…

For the sake of completeness, here is where I read that: http://www.ode.org/old_list_archives/2004-December/014735.ht... From looking at the game code, I see odd things like rollin…

The slightly longer and more correct answer is the source release contains the game engine source and the Doom 3 and RoE game DLL source. The Doom 3/RoE game data is still required…

It includes the source code for the expansion pack game dll (in d3xp). You'll still need the original RoE assets (when I went to install them on Windows, the installer crapped out …

I'm not sure where I picked up the info, and I haven't looked at the code to confirm it, but I believe the physics engine implementation is tied tightly to both the collision detec…

You don't. It's only implemented for Win32 (see neo/tools/edit_stub.cpp).

Surprising? I wouldn't say that; C# is used in lots of non-Microsoft places these days: http://www.fastchicken.co.nz/2011/09/15/c-its-just-not-porta...

Unexpected, but not without precedent. XNA on Xbox/Windows Phone 7/Windows, Unity3D across its range of supported platforms; it'll be interesting to see with Sony come up with.

You can get a pretty good idea from looking at the mod sdk code, which is available from here: http://iddevnet.com/doom3/ There's quite a lot available in the game code; the physic…

He may be referring to Scaleform (or another Flash GUI library; I don't think he specifies), but he's also talking about his experience with scripting in Doom 3- which I'm fairly s…

RAD game tools, purveyors of lots of 'middleware' for games, have developed their own Flash playback engine called Iggy. I don't know how it rates, but its an option: http://www.ra…

My understanding is, "drawing" (in-view composition) is largely, if not completely, software (Quartz2D). Composition between views is (can be, at least) handled by the GPU; and tha…

This isn't new news if you've been following this business since the start: http://news.ycombinator.com/item?id=2552563

As a complement, Chris Hecker has kept some of his notes regarding OpenGL vs. Direct3D around: http://chrishecker.com/OpenGL It seemed quite important at the time that he- who bega…

Reportedly, it isn't restricted to just in-app purchase: http://twitter.com/#!/jamesthomson/status/70095343605391360

I'm not an IP lawyer, but according to this other post the patent at issue was filed in August 1992: http://www.lodsys.com/1/post/2011/05/q-opinion-in-several-bl... Won't that expi…

It was recollection on my part; not backed by empirical evidence. For this exact case, though: wouldn't you better handle this with floating point exceptions?

I've had fairly heated arguments about this in the past and I'm curious to know if anyone else holds the same opinion: I contend that a normalize function is a really bad place to …

Digital Foundry has a series of interesting articles about measuring input lag in console games; I think this is the first: http://www.eurogamer.net/articles/digitalfoundry-lag-fac…

Another excellent resource is the archive of Erin Catto's GDC presentations (Erin is the author of Box2D). Box2D was first presented in 2006; the 2005 presentation is about an iter…

Spot on, I think; I would add that as well as being a subject matter expert, you will also need to be intimately familiar with the hardware architectures of the Xbox 360 and PS3, s…

To my knowledge, this is actually the second such fund being made available since late last year. I guess the first one was oversubscribed, which (I hope at least) augurs well. If …
