Integer math can generate amazing patterns when laid out over a grid. Even the most basic functions can yield stunningly elaborate designs! Your challenge = Write 3 Tweetable (meaning 140 characters or less) function bodies for the red, green, and blue values for a 1024x1024 image. The input to the functions will be two integers i (column number for the given pixel) and j (row number for the given pixel) and the output will be an unsigned short between 0 and 1023, inclusive, which represents the amount of the given color present in the pixel (i,j). For example, the following three functions produce the picture below: /* RED */ return (unsigned short)sqrt((double)(_sq(i-DIM/2)*_sq(j-DIM/2))*2.0); /* GREEN */ return (unsigned short)sqrt((double)( (_sq(i-DIM/2)|_sq(j-DIM/2))* (_sq(i-DIM/2)&_sq(j-DIM/2)) )); /* BLUE */ return (unsigned short)sqrt((double)(_sq(i-DIM/2)&_sq(j-DIM/2))*2.0); ![Pattern-1][2] /* RED */ return i&&j?(i%j)&(j%i):0; /* GREEN */ return i&&j?(i%j)+(j%i):0; /* BLUE */ return i&&j?(i%j)|(j%i):0; ![Pattern-2][1] The Rules = - Given [this C++ code][3], substitute in your functions. I have provided a few macros and have included the <cmath> library, and you may include complex.h. You may use any functions from these libraries and/or my macros. Please do not use any external resources beyond this. - If that version isn't working for you, make sure you're compiling with: g++ filename.cpp -std=c++11 If that doesn't work, please use the [alternate version][4] using unsigned chars instead of unsigned shorts. - You may implement your own version in another language, but it must behave in the same way as the provided C++ version, and only functions from C++'s built-ins, the <cmath> library, or the provided macros may be used to make it fair. - Post only your three function bodies - please don't include my code in your post - Please include either a smaller version or an embedded copy of your image. They are made into a ppm format and may need to be converted to another for proper viewing on stackexchange. - Function bodies (not including signature) must be 140 characters or less. - This is a popularity contest - most votes wins [1]:http://i57.tinypic.com/2iiik61.png [2]:http://i57.tinypic.com/2luvwpx.png [3]:http://pastebin.com/dSXQV1SR [4]:http://pastebin.com/Fb7nk6Ua
