nbartlomiej | 11 years ago | on: Show HN: PolyGen App, turn gradients and photos into pretty low poly patterns

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'll be happy to make a desktop version if users want it. Comment here, reply to this tweet (https://twitter.com/polygenapp/status/560846810735206400 ) or let me know in any way if you're interested.

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.

> How do I focus?

I've assumed that "Tap to snap..." works on the (right) button area only and tapping the photo triggers focus. This isn't clear though.

Remember that iAD doesn't work worldwide, it's only enabled in selected countries (Australia, Canada, France, Germany, Hong Kong, Ireland, Italy, Japan, Mexico, New Zealand, Spain, Taiwan, the United Kingdom, and the United States; see FAQ -> iAd in iTunesConnect).

Hybrid gaming might become a bigger thing when iOS8 is finally released, it should bring WebGL support. I'd like to see how e.g. pixi.js with WebGL renderer performs on mobile.

I've been able to use PhoneGap / Cordova in my iOS projects and achieve ~60FPS, but I've had to stay within some constraints (e.g. use GPU-accelerated CSS animations). As suggested, Crosswalk is an interesting alternative for Android.

Author of the blog post here. From my experience, achieving a native feel with a hybrid app on e.g. iOS isn't that hard. There are constraints, true. But it can be done.

My strategy is to use GPU-accelerated CSS transitions, test often on the real device and see how others are doing it, e.g. in UI frameworks (onsen ui, framework7, ratchet, etc).

nbartlomiej | 13 years ago | on: Foggy: jQuery plugin for blurring page elements

I like your point, I agree that you should be careful when using this effect.

However, in proper places blur feels very natural; after all, human eye works this way.

I think blur has lots of potential. I especially like these use cases:

- triggering blur effect after a dialog pops-up

- leading the user through a series of mundane forms, displaying the goal in the blurred background

I'd be interested to hear other ideas too.
