Metropolis 3D City Live Wallpaper
​

Introduction

Metropolis is a live wallpaper that streams urban, drone-scanned 3D scenes onto your home screen. It currently has 100+ 3D locations in North America and Europe, including:

The Empire State Building

The Statue of Liberty

Paris Las Vegas

Bordeaux Cathedral

and more

All these scenes are fully 3D like the ones in Pixel Live Wallpaper from Google. If you like Pixel LWP or Super Wallpaper, then Metropolis would be a good alternative for you :) Here is a trailer for Metropolis:

Performance Concerns

Here is the catch: Metropolis is built with Unity. Yes, that Unity game engine.

Now, before you close this page immediately thinking that's crazy, please read my explanation on why using Unity (might get technical):

Currently, the only 3D city model data source that I, as an indie app dev, can get on the market is the Bing Maps Unity SDK. This Unity SDK shares the same upstream data source with Windows 10 Map app and the incoming Microsoft Flight Simulator (well that is just a speculation). That's the main reason I am using Unity to build Metropolis. (I know there is Google Earth but I cannot rip the model due to copyright issues)

I certainly understand your concerns that Unity might destroy your battery life and available memory, and Metropolis does have a relatively high memory usage in current stages. This is mainly due to the SDK's streaming approach. Unlike Pixel LWP or Super Wallpaper in which the data is already baked into a static scene, Metropolis streams city blocks tile by tile, which comes with additional memory cost and draw-calls.

However, the battery cost should be on par with most 3D live wallpapers, especially if you enable the 'adaptive framerate' option in the app. And I will continue optimizing the app with newer Bing Maps SDK that is more memory-friendly. After all, you can always download the app for free and try it yourself.

(BTW, a fun fact: Xiaomi's Super Wallpaper is also Unity inside)
