Edit - And as for "why mobile-first", I wanted to make the app casual and approachable. You can take a photo of your teacup and have a cool low poly version of it in an instant. Or generate a pretty colourful wallpaper with one tap. But I'd love to build a desktop version too. Larger screen and finer control over the pointer would give some new possibilities.
Edit 2 - In case somebody didn't notice, you can generate a wallpaper for your desktop from the mobile app. Just choose a desktop option in the "Size" setting.
I've tried d3.js, but decided to go with iron wallaby's delaunay (https://github.com/ironwallaby/delaunay) implementation for performance reasons. The difference was especially visible when working with photos.
It's nice, good work. I wonder if you might be better off without the ads though. Not much revenue, and without them you can possibly build a bigger user base as a reputation point for your resume.
The ad made me buy the in-app purchase instantly, even before trying (it's placed nearly in the way of the action button).
So in my case, the ad worked as a immediate trigger to pay.
(I would have bought it a 1€ directly in the store, without any hesitation, too. So it made no difference in the end. I'm just a little annoyed that in the future I might have to restore my purchase).
2005-2010 | Concentric vector circles on everything.
2011-Present | Gradients with triangles on everything.
In all seriousness, this is a nice idea, but it seems really limited for just an app. It should be a photoshop filter! (or I'm sure GIMP could use some love)
This reminds me of voronoi diagrams, except the vertices seem to be applied as a best-fit around contrast and hue differences--then the cell being filled with the average color of such.
Beautiful. I bet you could get some very nice results if you use a Voronoi diagram using the color gradient as distance function. Even better if you chose points not randomly, but based on the slope of this distance, so they're concentrated in "feature points".
I can't try the app (stuck on a Gingerbread phone) but it seems fun. I'm eager to try it.
As far as I can tell, the user chooses the location of triangle vertices, right? It would be interesting to try a genetic algorithm there though it probably fits best in a desktop version.
Also, did you experiment with Voronoi diagrams instead of triangulation?
For abstract patterns, points are chosen "randomly" (grid with randomised offsets). For photo-based ones, I'm using JSFeat's YAPE06 (http://inspirit.github.io/jsfeat/#features2dcorner), plus some own customisations. I'm constantly looking for ways to improve generating photo-based patterns; if anyone has some ideas here, I'd be happy to listen.
I've played with genetic algorithms, but without anything practical. Indeed, this might be more appropriate for desktops.
I've experimented with Voronoi too, but the results weren't as pretty. The cells were more rounded; and the low poly style was gone.
I'm getting a force close when trying to choose a picture on a Sprint Samsung Galaxy Note II. I have no experience with android development and don't know how the force close reports work, but one was sent and I hope you can figure out the bug.
Really looking forward to trying this out! Will be great for wallpapers.
I'll be looking into it. In the meantime you might experiment with a different camera (pick "System" in the "Camera & Gallery" option). And many thanks for your comment.
Crop aspect ratio matches the "Size" setting, located one screen earlier; so it's a feature for now. I plan to revisit the crop screen sometime in future and bring more control there. Thanks for your comment!
The regenerate button seems to cycle (inconsistently?) thru the grain sizes. Undesirable; if I pick a grain size and regenerate, I'm looking for a suitable arrangement at that size.
The "refresh" button randomises as much as it can, but you can prevent a section from being randomised by "locking" it (clicking on the tiny lock icon).
So you can pick a size, lock it and hit "refresh" as much as you wish. I'm glad that you like the app, cheers!

Personally I would use it the most from my computer, considered a port ;)

Surprised to see that this wasn't authored by Mario Klingemann, creator of the very clever LowpolyBot:

The back-button gets hidden per default and when used he doesn't go back to the main menu but leaves the app.

Works fine when rendering with colors.
Anyone else seen something like this?
