Just about finished my program for my final project, it's a functional query language based on the functional data model. It might not be as cool as making a compiler because it's interpreted but it was pretty fun to make and learnt a lot doing it  . Now onto report writing!

This is a Tron lightcycle game that my team and I recently finished for our 400 level computer graphics class (that will be a listed as a 300 level class next semester, like it should be). Click here for the full 864x646 image.  Click here for the full 863x647 image. It has support for 1/2/3/4 players with split screen, or you can watch 4 pretty bad AI lightcycles go at it. There are gratuitous amounts of particles when you die that work (sort of) physically with the exception of collisions. We also included the bouncing wheel from the original Tron lightcycle scene that shows up when someone hits a wall. There are occasionally collision problems, but for the amount of time that we wrote this in I'm surprised how decent it is. Due to the short amount of time we wrote this in (one week), we had to cut corners and ended up drawing everything in immediate mode. If I was to continue actually working on it I'd probably put all the wall coords in a vbo so that it doesn't slow down like crazy with 4 viewports. Also, the OBJ Loader was written by someone in the group and is pretty poorly coded. Here's a link to a binary that should work under 32bit windows with .NET 2.0: http://senduit.com/26c255 If your graphics card doesn't support aux buffers you can press g to turn off the blur effect on the playfield. Buttons (since they aren't listed) for player 3 are left arrow/right arrow, player 4 divide/multiply on the numpad.

tofufish posted:This looks amazing, Ive been looking for a decent program like this for quite a long time. Anyway for us to keep updated on the updates/release time? Do you have a link to that other manager you were talking about? It's very close to release now. I was slacking off on it because of school and Street Fighter IV, but I picked it up a few days ago and did some good stuff. All of the functionality is there, I'm currently re-engineering some of the stuff to make more sense since it is an open source project. Also working on getting as many bugs as I can fixed before the initial release. So to answer your question, soon

 Click here for the full 956x518 image. A crossplatform (Windows and OS X - Linux support shouldn't be hard to add in the future) Python hard drive benchmark. Generates files on one drive, uses the operating system's shell to transfer them to the other drive, then saves the results to a .csv and plots the data using matplotlib. It's intended to simulate a real drag-and-drop file transfer as closely as possible. The only thing left to do is package it so that you don't have to install python, matplotlib, numpy, and pywin32 to use it. I've been thinking of making a thread to ask people to beta test it, because there are about a million different use cases and I haven't had time to try all of them.

This is less of a project and more just killing time, but I thought it was kind of neat. I'm trying to apply some optimizations to a simple Mandelbrot app. The pixels in red are the ones it decides it does not need to calculate. Click on image for app (Flash 9); in app, click to zoom. Zooming is limited by AS3's Number precision, which is 64 bits and I suck at reading documentation. Not UNIX fucked around with this message at 07:22 on Apr 15, 2009 |

 A friend told me about reaction-diffusion systems, and they seemed pretty interesting. I write a lot of javascript for some reason, so I ended up writing the things using JS and canvas, which can be found here. Javascript is pretty slow, especially at this kind of thing (and I wrote/tested it all on an Eee,) so I decided to write the thing as a desktop app with a somewhat decent UI. I figured it was time to learn C# too, so I'm doing that for this project. The only thing left to do is generate a little settings table when the reaction-diffusion module is changed, as each model has its own parameters and things. Edit: poo poo I sure sound interested! Reaction diffusion systems model chemical reactions and how they diffuse in a space. They can generate all kinds of patterns found in nature and are fun to watch as they change and form. broiledmeat fucked around with this message at 17:02 on Apr 17, 2009 |

I'm working on an internal app to do our invoicing. It uses PHP and JavaScript with some AJAX and it creates PDFs from the invoices. A key design goal was 'Disco Shine.' Other than that it's mostly a simple DB app.

 For my final year masters project designing a program to help solve rubik's cubes. The idea is that it uses a web cam to track the position and state of a rubik's cube in real time, and show a 3d reconstruction of the user's perspective of the cube (the opposite side to what the webcam can see). I've spent quite a while on the image acquisition side of it and finally have it identifying and labelling some of the faces on the cube - now it should be trivial to search around to find the remaining faces!

This is a great idea for a project. Does the information in this picture uniquely determine the arrangement of the squares on the other side? You'd think that the opposite corner, for example, could have any of 3 orientations, but maybe there are some subtle constraints. I also wonder if you're finding indiviual colored squares without much context, or if you start by estimating the overall orientation of the whole Rubik's cube and use that for finding the squares.

Fecotourist posted:This is a great idea for a project. This is not enough information to determine the overall state of the cube, but it is enough for the application to know which side of the rubik's cube it is looking at. The idea is that the cube will be rotated so that at least one image is captured of every face until the position of the cube is determined. after that the program will assume that no moves other than the instructed ones have been made (although if it detects that the cube is in a different position it will update the solution, but if a move is made off screen it wont detect it until it sees the cube again. I did begin by estimating the overall orientation of the cube and using this information to find the individual faces, but this doesn't cope so well with fingers obscuring faces, and capturing the rubiks cube mid move (when the sides are not aligned). A basic summary of the process I'm using to find the faces is: - perform harris corner detection. This finds points which match up with the corners of each individual face (although not all of them) as well as plenty of back ground noise - Go through each pair of corners found, and for those within a certain distance of each other, analyse the variations of colour on a line between them. When a solid line of colour (in the HSV colour space) is found, this line is added to a list of candidate lines - For each pair of candidate lines, see if they intersect each other with the same colour values and similar size. If they do, add them to a list of candidate faces - For each candidate face, perform a flood fill (in HSV colour space) starting from the intersection point of the two lines. Then update the original face corners to match the new filled area There are a few extra steps involved but that summarises the key stages. And it is fairly fast - takes about 50ms a cycle.
