| Sep 6, 2015 at 2:16 | comment | added | A Frayed Knot | @trichoplax I agree with your first comment, but I decided to choose Manuel Kasten' s blue mandelbrot, because I've been using it as one of my backgrounds ever since he posted it. I didn't want to choose something with too few votes seeing as I tagged it as a "popularity contest" | |

| Sep 5, 2015 at 23:24 | comment | added | trichoplax is on Codidact now | The tablecloths answer is my least favourite among my own answers to this question, and certainly can't compare to some of the amazing answers by others. | |
| Sep 5, 2015 at 23:22 | comment | added | trichoplax is on Codidact now | Although I'm grateful, please don't accept the tablecloths answer. Even today there are still new votes coming in with more interesting answers bubbling their way towards the top. I encourage sorting by oldest and seeing how the answers developed over time, and having the highest voted pinned to the top will only serve to skew the voting further. | |

I'm curious if you considered just using GLSL and glsl.heroku.com or shadertoy.com. The cool thing is their viewable online. Just provide a template, allow 140 chars in the middle of say void main() { /* insert 140 chars here */ };

| Aug 7, 2014 at 23:43 | comment | added | trichoplax is on Codidact now | This type of question encourages participation in code golf. I'm generally disinclined to answer a straight golf question as I'm not confident of doing well. With this type of question the byte limit makes me try a simple answer, learn golfing techniques along the way, and then use them to make more complex answers. This is like a stepping stone into answering straight golf questions. I think it could be key in bringing more people in. | |

| Aug 6, 2014 at 19:17 | comment | added | DreamWarrior | Ugh, I didn't see it, but it was listed, haha.... Anyway, the fact remains that the answers using short still don't produce what their sample images show. For example, faubiguy's answer is just a black and white image of a gradient circle with a smooth diagonal gradient behind it. And cjfaure's answer is just a black canvas (though without the proper byte-order I get color). Oh well, I guess them's the brakes. | |
| Aug 6, 2014 at 19:04 | comment | added | DreamWarrior | @ManuelKasten tried that, still didn't produce an equivalent image. However, it is required on my machine, and thus did produce more sensible images! So thanks -- don't know why I didn't think of that, though I looked up the PPM format and didn't see endian-ness listed, so maybe that's why :-). | |

| Aug 5, 2014 at 20:50 | comment | added | Manuel Kasten | ImageMagick should work. Didn't try display, but convert was fine. On little endian systems you might need a htons() to write the color values like so: color[0] = htons(RD(i,j)&DM1); The 16bit ppm format is big endian. Declaration of htons is in arpa/inet.h | |

| Aug 5, 2014 at 18:25 | comment | added | DreamWarrior | For those using the unsigned short (non-alternative) version of this, what are you using to display the results? Neither my version of Gimp (2.2.13) nor ImageMagick's display (6.2.8) seem to like PPM files w/ 1023 as a max. Many of these answers don't seem to work at all with the alternative version (and some produce severe palette shifts with it). | |

Shortened names of the 3 color functions
|
| Aug 2, 2014 at 23:21 | comment | added | A Frayed Knot | Haha good call. Just a few minutes here... | |
| Aug 2, 2014 at 23:15 | comment | added | trichoplax is on Codidact now |
If you are going to add forward declarations and allow mutual recursion, is there any chance you could also shorten the function names, for example r() instead of red_fn()?

Forward declarations in pastebin files to allow mutual recursion
|
| Aug 2, 2014 at 23:03 | comment | added | A Frayed Knot | @MartinBüttner That sounds interesting. I'd say that isn't really in the scope of what I was looking for... but I'm curious. Updating it now. Show me what you got! | |
| Aug 2, 2014 at 21:34 | comment | added | Martin Ender | @KyleMcCormick could you maybe add forward-declarations of the three colour functions to your framework? that would allow some funky mutual recursion. also, people porting the framework to other languages will get those capabilities for free anyway. | |

Allowing complex.h

| Aug 2, 2014 at 20:34 | comment | added | A Frayed Knot | @githubphagocyte We'll say the opening/closing braces don't count toward your 140 char count. | |
| Aug 2, 2014 at 20:34 | comment | added | A Frayed Knot | @MartinBüttner Feel free to do whatever you want in the space between the braces, but please do not change the function signature or write any external functions to call inside these. Also, changing to allow complex.h. | |

| Aug 2, 2014 at 12:24 | comment | added | trichoplax is on Codidact now | @MartinBüttner your macro question makes me wonder if it is acceptable to call, for example, red_fn from green_fn, with two arguments that don't necessarily relate to pixel coordinates. | |
| Aug 2, 2014 at 12:20 | comment | added | trichoplax is on Codidact now | Am I right in thinking that the function body doesn't include the enclosing braces? | |
| Aug 2, 2014 at 11:38 | comment | added | Martin Ender |
@KyleMcCormick Do you consider it cheating to define a macro in red_fn and use it in green_fn and blue_fn?

@Kyle I've tried both your examples, but both give a different image to what you've shown and the second one raises a division-by-zero error that I fixed with i|j->i&&j. Mind looking at it?

Added option for alternative languages
|
| Aug 2, 2014 at 5:02 | comment | added | A Frayed Knot | @algorithmshark I was considering allowing other languages, but I'd have to require that whoever chose to do so would have to implement a nearly identical framework. I chose to make it this way to make it easier & quicker for people to work out a quick solution, rather than making it a more in-depth problem. | |
| Aug 2, 2014 at 4:48 | comment | added | algorithmshark | Added C++ tag because the nature of the rules excludes other languages. We generally prefer language-agnostic challenges unless they have a good reason to require a specific set. | |
