Not nearly as impressive as most of the other stuff in this thread, but I just finished the realtime lighting engine for my stealth game! Whoo!

Not nearly as impressive as a lot of the stuff here, but I recently got moved to the team doing object recognition and reconstruction. Only user input is a single click to select what object to recognize. With simpler objects like chairs and tables, the application can reconstruct 3D models using a single image. It's still very much in the beta.

What's the hue if there are multiple routes to the same location? Or does it only work for mazes with one path to each location?

I'm guessing it uses the lowest distance to the location, unless he's using something other than A*.

I'm using Dijkstra's algorithm because it lets you find the shortest path between a vertex and every other vertex on the graph, while A* just uses heuristics to find a path between two vertices on a graph.

A* is shortest path, too. It's also faster than Dijkstra, if I remember right.

I have done a lot more work on my maze game including MULTIPLAYER and an editor that is way faster. Also create an account to customize your guy or you can just stay anonymous as a blue square. The starting area is pretty turbulent so if you want to draw something cool just head to the west or east for some clean area. WASD moves and Space draws.

The digit on the left is a raw bitmap with 784 pixels and the digit on the right is a reconstruction by a trained neural network based on a 500 bit binary vector. So, the model drew the one on the right knowing only the 100 bit values.

I'm working on a hand written character classifier (MNIST) for a class I'm taking. I'm replicating Dr. Geoffrey Hinton's work using neural networks to reduce the dimensionality of data (using discovered binary features) and then I'm going to use a K Nearest Neighbor classifier to evaluate how good the reduced data is. Once I've done that, I'm going to do a similar thing with a slightly modified model using discovered continuous features and do a similar evaluation. The overall goal is to figure out which method works better. I suspect I should be able to use fewer features to get comparable classification performance with the continuous model, but who knows!

For a broad overview, check out this paper (very approachable to the layman!):

Finishing up a sprite animation editor which imports/exports XML.

EDIT: Added Internet Janitor's suggestions. Have origins now. No auto-bounding box yet. Also cropped for tables and added blue blobs for added work safe-ness.

Internet Janitor posted:

Jo: On the one hand, that seems reasonably useful. On the other hand, you created something new that makes XML and will inevitably create other new things that read XML.

Does it figure out bounding boxes automatically from transparency, or do you set them manually? If you're dealing with variable-size frames you'll probably want some way to define the origin for each one.

TilED, the map editor, exports XML. I figured rather than hack together some binary format it would be easier to just re-use the code. Beside, Python has an easy XML implementation and Java can just copy/paste my loading code.

As for the origin, you're right. Thanks for the suggestion.

Wrote an iterative permutation generator (rather than using itertools) to cycle through an alphabet. Added support classes and hosed with parallel python to create a distributed hash cracker. Whoo lunch break!

I'm peeved that DNF and Deus Ex: Human Revolution are so far away. I decided to start (or restart, depending on how much code I use from Devil Gear Solid) and make a 2D stealth game. Hoping to have a decent demo by the end of the weekend.

I suck at drawing sprites.

Any progress on this? I've always been bummed out by the lack of indie stealth games.

Yes. I'd say I'm close to 35-40% done. The basic pieces are in place, but I need to refactor the mapping system and make the entities less stupid.

EDIT: I should say I'm aiming for release of a one level demo on May 15.

Why not just use the OpenGL orthographic camera? A perspective camera at optical infinity is practically the same thing, but you need to mess with floating point imprecision.

Roflex posted:

Maybe I'm misunderstanding the Ortho view but the way I did it, it's still 3d/perspective at the core, allowing free view from any angle.

I'm not one to comment on your implementation -- I haven't seen it. My curiosity is why would one bother doing strange tricks to make a perspective camera into an orthographic one? Why not use an orthographic one in the first place?

I assert the following:

Orthographic projection will accomplish the isometric viewpoint you desire.
Orthographic projection will allow this viewpoint to be achieved without moving a camera to optical infinity. (Or close to it.) Additionally, with orthographic views, you don't have to compensate for the huge draw distance by zooming.
Orthographic cameras offer greater numeric stability over perspective cameras under these circumstances.

Water under the bridge, though, since the implementation is done and fun was had doing it.

I posted a link to a prototype game a while back. Ported it to Android and released on the Google Play Store. It's very basic, but it's kind of a fun time waster. There are two game modes: reflex and cone hunt. In reflex, you weave between cars on either side. In cone hunt, you try and smoosh construction cones.

I've been working on a stupid puzzle game for Android and the iPhone.

It's conceptually pretty simple. Take turns. Black moves first. Put down a piece, then slide a row or column. Pieces wrap around the edges. Get four in a row to win.

There's also a super-secret beta copy if you've got Java: https://dl.dropboxusercontent.com/u/51917/ofu.jar

This is cool and if you have any details of what you are doing behind the scenes I would be interested to hear them.

You're going to be disappointed. It's a stupid simple thing. It starts by pulling stock price data, then for each company randomly samples tweets with relevant words, converts them to ngrams (order two), and attempts linear regression with the term frequency as the input matrix. For foreign terms (most of them, given the sparsity of the matrix), it pulls a number out of its rear end. The volume of the last trade is the 'confidence' until I stop being l lazy.

Taking a break from some of the harder math stuff to throw together a UI for labelling vehicle data. Summarily, the air force UAV dataset contains a ground truth, but it sucks dick. Average 'center' can be as far off as 100 pixels from the real vehicle. Since I'm not one to label 12,000 tracks by hand across 1TB of images, I made a backend that breaks things down into small chunks for processing by an army of undergraduates and the interface to add centers and forward vectors.

There's still some usability stuff to be considered, like keyboard shortcuts and auto-switching from normal to create mode, but it works well enough for me to make a few hundred labels.
