comment Optional samplers in shaders
Actually, you'll most likely get BOTH useless texture lookup AND a useless test, the way shaders work =)

comment Do 2D games have a future?
Most "3d" games are actually 2d. Even mass effect 2 is, from a physics point of view, a 2d game.

comment Are the Marek-knows tutorials any good or still relevant?
@iamcreasy Yes, there is. First, most of the stuff you need to learn are not really dependent on how you do rendering, and second, if you want to support low-end chips (such as intel's), shaders are still not there. All this said, I don't know if Marek's tutorials are good, I'm just answering your question of whether it's still relevant, and yes, it is.

comment What are the steps to get sound from reality into a game?
Too bad I can only vote this answer up once =) As I've understood it, for most movies made today, nearly 100% of the audio is re-created after the fact, sometimes even including all voice acting.

comment What exactly is UV and UVW Mapping?
I don't understand what you mean. 3d textures may be useful in other uses than as simply textures, though; if some data a shader needs conveniently maps into a 3d array, that would be one use. But as a "normal" texture, they're generally just a waste of memory.

comment What exactly is UV and UVW Mapping?
No, because they're generally speaking never used. There's always some cheaper way of doing the same thing. Think of the chopped items in wii sports plus; you can break the items in any way you wish, and see the "internals". They could have wasted huge amounts of memory by making them 3d textures (assuming the hardware even supports that), but it's much cheaper to simulate that with a couple of 2d textures instead.

comment Getting the number of fragments which passed the depth test
Does apple support AMD_performance_monitor? If yes, you may be able to find the counter that shows passed pixels. Do note that this is very, very device specific even if you get it to work.

comment What is a good way to test demand for a new game platform?
I think we need a bit more information on what you mean by "game platform". Apple generally dislikes meta-platforms and kills any app that hosts other apps, if that's what you meant.

comment What is causing these visual artifacts on my OpenGL sprites?
Here's a page regarding pixel/texel centers: drilian.com/2008/11/25/… - and I meant OpenGL dithering, not photoshop dither (glDisable(GL_DITHER))

I didn't mean you'd use the editors; I meant you can look at their source code for reference on how to load the data.

about the invisible bg: it's hard to tell from the screenshot, but it seems to me like you might have dithering enabled.

comment What is causing these visual artifacts on my OpenGL sprites?
about the sprite: is your uv wrap mode set to clamp (assuming one texture per frame)? if you have several frames in a single texture, it's just a matter of defining your uv coordinates so that you take the texel center into account.
