I've been working on porting some of my Processing code over to regular Java in NetBeans. So far so well, most everything works great, except for when I go to use non-grayscale colors.
I have a script that draws a spiral pattern, and should vary the colors in the spiral based on a modulus check. The script seems to hang, however, and I...
What is the algorithm for storing the pixels in a spiral in JS?

A friend was in need of an algorithm that would let him loop through the elements of an NxM matrix (N and M are odd). I came up with a solution, but I wanted to see if my fellow SO'ers could come up with a better solution.
I'm posting my solution as an answer to this question.
Example Output:
For a 3x3 matrix, the output should be:

I'm trying to fill an array in spiral order. So far, I can print the array in spiral order, but is there a way to modify the array so that i can fill it in spiral order and then just print the array? I'd like it to go in decreasing order like a countdown. Please help!
public class Spiral {
public static void main(int m, int n) {

Hi,
I am preparing for an interview and have been stuck on this question for quite some time now. Could anybody please help me with the code. If not complete then may be a snippet of it?
Please..

Does anybody have a PHP (or other language) script for drawing a spiral. A simple (Archimedean spiral) would be just fine. Of course the principle is simple but coding it in SVG or GD would take some time, so I wonder if somebody has one ready :-)

What's more appropriate than a Spiral for Easter Code Golf sessions? Well, I guess almost anything.
The Challenge
The shortest code by character count to display a nice ASCII Spiral made of asterisks ('*').
Input is a single number, R, that will be the x-size of the Spiral. The other dimension (y) is always R-2. The program can assume...
I have looked at this example using php and GD to piecewise-render a spiral with small arcs. What I would like to do is render an approximation to a spiral that is as mathematically accurate as possible.
Inkscape has a spiral tool that looks pretty good, but I would like to do the spiral generation programmatically (preferably in Python...

Task:
For a given position in 2D array generate list of surrounding positions located in radius.
For example:
input: (1, 1)
radius: 1
output: ( (0, 0), (1, 0), (2, 0),
(0, 1), (2, 1),
(0, 2), (1, 2), (2, 2) ).

for(radius <- 1 to r) yield ...
