Context:
Watch: http://www.youtube.com/watch?v=AWcbj7ksqwE
I'm familiar with OpenGL / GLSL / C++ / C
I've done some audio programming.
Never mind trying to compress it down to 64k or 4k for the moment.
I don't even know how to procedurally synthesize something like the above demo.
Question:
I realize the demoscene is somewhat of an underground blackart. However, is there any good tutorials / walkthroughs on creating one of these? Something like:
"Demoscene for Dummies that know OpenGL / GLSL / C++ / C"
I also realize there are toolkits designed to compress down the code -- however for me compression is not important at the moment. I would be happy to merely learn how to create something like this.
Concise Question:
Can anyone suggest a good tutorial / walkthrough on creating a demo scene step by step, for someone with enough of a technical background to understand the individual steps (but yet unable to see the whole picture).
Thanks.
Here's a link to a pdf written by the programmer behind the technical magic. It's a really great read.
http://www.iquilezles.org/www/material/function2009/function2009.pdf
His site itself is a treasure trove of information regarding demoscene programming techniques.
I wrote a 4k demo which won 1st place at an Australian demoscene party (Syntax)... http://www.youtube.com/watch?v=t7anicyRI3w

I am a beginner in programming world and i have basic knowledge in Python Java and good knowledge in C++. I have started learning web development in my summer break and i would like to start Data structures and Algorithms .
Please suggest some good reference/book/content for my Data structures and Algorithms learning.
welcome :)
Unfortunately, since this question does not have a fully objective answer (i.e. answers vary on opinions), it is not a very good idea to ask it on Stackoverflow.
There are really nice books which we all still get help from. You can find them on web with a basic search, read comments, and so on.
I don't believe that you can choose a disaster-like book for beginning your adventure, I mean, you will learn a lot somehow.
While you are learning, do not hesitate to ask if you face with something which you would need help, just be careful about its answer being objective :)

I am a high school student who live out side of the USA.
So... please excuse any mistake.
I am planning to study for Olympiad in Informatics(I have never participated in this contest) and I am going to try on next year since it begin in April in our country I think I still have a time to prepare for it. And actually, I am kind of interested in data structure and algorithms . Although I cant get a good result from the contest, it would be worth experience to me.
However, there are no one who have ever participated in this contest in our school. So, I have no idea how to prepare.
I sure know how to code with python ,C ,C++ (but I am not good at it..)
So... If you guys know about it, please just give me some information. like books and way to prepare.
First research what the contest is about.
Learn your stuff. If it's algorithms, then I suggest something like Skiena, The Algorithm Design Manual. I think there's also a competitive programming book by Skiena.
Then practice. It looks like it might be similar to "classical" programming contest, so it would make sense to try:
- https://uva.onlinejudge.org/
- http://www.spoj.com/
- Any of the numerous online judge systems.

I'm a novice in the field of ellipse detection/extraction. But I know this topic has a long history. Although there are tons of papers addressing ellipse detection, I can hardly find any C++ implementations of these advanced algorithms such as Straight Line HT (SLHT), Fast Ellipse Hough Transform (FEHT), and Randomized HT (RHT). I'm curious Why the researchers don't put their code online such that more people can benefit from them? Can anyone kindly tell me where I can find any of the C++ implementations? Thanks.
(PS: I'm familiar with OpenCV. I know OpenCV has few implementations such as fitEllipse and HoughCircle.)
A lot of image processing research is done in Matlab, there are generally implementations available in that language. The reason you don't see any C++ implementations is because they would be much more about the details of implementation (memory management, performance, etc) rather than the actual algorithm; Matlab is much more succinct about this.
If you really want to get to learn about image processing algorithms, you'll probably want to learn to read Matlab code.

Can anyone recommend any software/books required to learn and build fractal patterns? I want to also be able to animate the fractal patterns too. Like something off of winamp.
For book on animated fractal Fractals: An Animated Discussion with Edward Lorenz and Benoît Mandelbrot could be what you want.

http://mitpress.mit.edu/books/flaoh/cbnhtml/
I am working on a project in java for creating fractals (flame fractals).
The user provides a script file in javascript, that takes care of the interpolation between fractals. Also, as input, one can provide a file that affects an animation in some way,
so this is the way to make an animation change to some music,
see for example
http://www.youtube.com/watch?v=imDPqR9cDL8
I can send you the source code if you provide me with an address.
There's lots of fractal programs out there.
I know that Ultrafractal is pretty popular, but not free.
As far as free ones go, there are programs such a ChaosPro and others. A quick google search will find them for you.

Where should I start to write a custom language for PLT? Is there any information on the net (or maybe information in the manual I'm overseeing?) Or are the existing language packs the best reference for such a task?
Thank you in advance!
The book - Programming Languages: Application and Interpretation might be a good place to start, especially chapter XII "Domain-Specific Languages and Metaprogramming". It uses PLT Scheme for the code samples, and the entire book is a worthy read.
This may be no longer relevant, but worth a mention. While PLAI is a good read, it is intended to be a general textbook on programming languages. If you want to get some specific details about creating new languages in PLT, then you are likely to be interested in a tutorial that I have given in DEFUN09 about this. I didn't make this public yet, since there is still some more work to do to get it in shape, but it is likely to be a useful resource if you're interested in this. (I will eventually turn it into a guide that will be included with the PLT documentation.) If you're interested, you can email me -- I'll send you a copy and I'll also be happy to get any feedback.
