I've actually been working on a NES emulator on and off for a few months (video). And after my first weekend working on it, it was looking like this: Getting the basic cpu and graphic output working really doesn't take too long but when you start trying to emulate 100s of little undocumented behaviors which all games make use of to varying degrees, it starts to get pretty time consuming. And even now every once in a while the NES community will discover some new feature that no one knew the hardware was using that is only used in maybe 1 game.

Another one of the iPhone apps I'm working on. This one is the official app for the New England Patriots 2010 season.     No iPhone 4 high-res support yet unfortunately (due to some of the libraries we are using that haven't been compiled for iOS 4.0 yet). It's a neat little app if you are a Pats fan. All the news content is directly aggregated from their main site, so it's not a bunch of neglected mobile-specific crap.

Is it true that in Handegg games (sorry, I refuse to call it "Football") that players and the ball are tracked using various technologies so their positionduring the game are continuously recorded? I've heard people speak of it, but don't know for sure. I was wondering if maybe you could write an app that takes that data, and renders a 3D scene of the game on the iPhone so people can see how a match went (or is going, if the data is available live) without needing to burn through their data plan downloading actual video. ...just an idea. What do you think?

 Automatic updater for goodreads based from the XML data on ereaders (currently just my sony prs-600). Two of the books up there are the result of not having proper metadata about the books and goodreads kinda taking it's best guess as to what they are. Two of them are just evidence that my reading choices as of late have been total poo poo. Oh and I can finally talk about what I have been doing for work.

I've heard people speak of it, but don't know for sure. I have no idea. The NFL does have people who input play-by-play of everything that happens into a system which can real-time aggregate the data to other sources. That's what powers stuff like those Flash apps where you see a football field that updates with arrows and poo poo as each play happens (Yahoo Sports Football and other stuff use this I think). A 2D or 3D abstract rendering of the game (you aren't going something that looks like Madden) is entirely possible with just this feed, it contains lots of information. I don't believe the feed is public however. EDIT: poo poo, meant to put this in my other post, my bad.

I'm actually making a full game, the idea being that you have to cheer on your world cup team to the finals. How well you play has no bearing on whether you win or lose; if you lose, you just pick another team and bzzzz on. Spoiled since I kind of want it to be a surprise to some people.

OneEightHundred posted:I think the best way to do Vuvuzela Hero would be trying to stop 6 Vuvuzelas from playing instead of making them play. A game where you play a hidden sniper sneaking about on the TV camera gantries on the roof of the stadium, you will be paid a large sum by FIFA to eliminate each person in the 60,000-strong live audience caught playing a Vuvuzela. The justification for back-story of the game hinges on the fact FIFA is opposed to introducing technology to the game (such as in this case, adding a simple anti-300kHz filter) and prefers to rely on the frailty of human agents, in this case: you. Part of the challenge is spotting the difference between a bright orange vuvuzela and the bright orange beer industry whores. ...and since the scenes involve billions of polygons for each spectator and high-qualtiy scenery means you might get at most 0.001FPS making it even more challenging, and hence, fun to play!

Yeah it was playing at 48bpm, I had it that low for testing. Still got some minor issues with timing detection at higher tempo (i.e. it's basically impossible to hit some notes), then I'm cleaning up the menus and finishing up with some graphical polish. Should have a full beta out this week.

I'm not nearly at the same level as a lot of you, but I've been trying to learn OpenGL, Cocoa and Objective-C, and have been working on creating a Collada model loader, with geometry and skeletal information loaded for iPhone. So far, using TBXML, I can parse a Collada file and load and display geometry and load the skeleton and bone information. Still working on linking the skeletal information to the bind pose, and then will work on reading actual animation. Eventually I'd like to create a game or something out of this, but for now, just learning for fun/hobby. This is all done using OpenGL ES 1.1, but I might switch to ES 2.0 if I ever get a device that can support it. For reference, loading a ~1 meg Collada XML file with 4500 polygons takes about 8 seconds on iPhone 3G. Or, about .006 seconds on my Macbook Pro. Model was taken from the Collada test model repository, but refined to use <Triangles> instead of <Polylists>  Click here for the full 1029x490 image.

I've heard people speak of it, but don't know for sure. http://mlb.mlb.com/mlb/gameday/ MLB has been doing this for a few years now. They show every pitch along with its supposed trajectory and placement. Their stats (96.1mph, 13.5" break) are pretty precise but I have no idea how accurate they are. Especially with pitch speed since they don't specify if it's when the pitch leaves the pitcher's hand or crosses the strike zone. I remember seeing a job posting for MLBAM a while back for pitchfx operators; it seemed pretty automated from the description they gave about the system.

Looks like in this thread the 3D stuff is the most popular, so here's mine   Click here for the full 640x480 image.  Click here for the full 640x480 image. It's a Z-buffered software rendering engine with flat and gouraud shading (with one diffuse light), texture mapping, and frustum culling. The main gimmick is that it isn't a lib, but a standalone (SDL-based) program that reads drawing instructions from STDIN, and optionally dumps mouse/keyboard events, or rendered framebuffers, to STDOUT. There is a description language (parsed with flex/bison) for defining geometry, using some usual basic solids, polygons, or used-defined objects. The scene can be changed between multiple frames (e.g. by changing the transformation matrix on defined objects to move them). This way any program that can write to STDOUT can generate fairly complicated 3D animations. Handy for visualizations, for example. The program is called Projector, is utterly undocumented, and available from svn://repo.hu/projector. Interactive 3D programs can be made by connecting Projector's STDIN/STDOUT to another program with two pipes. You can get Projector to report a position where a ray shot towards the mouse intersects a defined plane - here this is used by a 3K AWK script to display simple objects on a map, movable by the mouse:  Click here for the full 640x480 image. A C program using ODE for bouncing lots of stuff off of each other, dumping the object positions and orientations (as quaternions) to Projector:  Click here for the full 640x480 image. We used Projector in the Challenge 24 programming competition. The competing teams had to control three helicopters in a helicopter simulation (also done using ODE), and could view a real-time video stream from a "camera" on one of their helicopters. The video streams were served by xinetd, that ran a shell script that emitted a few HTTP headers, then called a pipeline something like: netcat (from the simulation server) | AWK (for transforming simulation state to Projector instructions) | Projector | ffmpeg (for encoding into Flash video) It looked like this:  Click here for the full 640x480 image. One interesting tidbit: the terrain engine converted a 16384x16384 heightmap + texture to a bunch of gradient-shaded triangles in a quadtree. To make the block cutoff look nicer, a fog effect was needed. The Z buffer has the depths in floating point, and calculating the fog per pixel in the usual way was rather too slow. In the end, I found a way with direct floating point hackery - using the bits in the Z FP value with a bitmask and some shifts gives a pretty nice alpha (but this way the fog density/distance is not variable in runtime).

Here are some final screenshots of the Hacker News app I submitted recently.   Of course, this got rejected "because it is a web clipping. Applications that only display a web page do not provide sufficient functionality beyond what a user can experience by adding a site to their Home screen using Safari." Death to Steve Jobs. There is already a sufficient difference between this app and Safari that makes me want to use this app. How should I change this app so that it will pass review?

I've been writing a visual shader editor for Unity 3. The shader system in unity is really nice but to hard for the average artist to use so I'm writing a system to make it easier. It outputs unity shaders that can be compiled and run ect. I'm most happy with the validation systems I built into the graph (it's self validating so you can't write a bad shader), and the preview tools that let you see the shader without leaving the editor (the unity editor api's not easily allow this and it took me quite a bit of time fighting to get it working properly). Here is a simple shader that does additive blending from two textures. There is still quite a bit of work to go but it should be pretty ace when done. I've validated that this kind of thing can work in unity, so now it's just grunt work to get it done.

That's really awesome. Also, I'm really impressed with your UI concept of validating so it's impossible to make a valid shader. I know it takes a lot of extra coding for small UI stuff like that, but it's so worth it when someone else has to use the app.

Strumpy: Looks cool, although all your operations are flipped horizontally - every graphics program that uses nodes for content manipulation/creation (no matter the exact type or field of appliance) has inputs on the left and outputs on the right. But I'd assume that's not a big thing and maybe you can even add a toggle for it in settings or something.
