Epic’s new RealityScan app can make 3D models from smartphone photos

Epic Games has announced a new smartphone app that can construct 3D models of objects from a series of smartphone photos. The idea is that you’ll be able to use the app, called RealityScan, to scan an object in the real world — say, a chair — and then bring the scan of that object into your game or project.

You can see how it works in the video at the top of this post, which features somebody scanning a brown chair, the result of which looks like a handcrafted 3D model. The app is currently available in a first-come, first-served beta via Apple’s TestFlight platform that will be open to 10,000 users.

I got into the RealityScan beta, and using the app is pretty straightforward. To take a series of photos, you can hold the capture button down or take the shots individually, and as you do, you’ll want to slowly move around the object to take various shots. The app asks that you take at least 20 images. Once you’re done scanning, you can send the model to be uploaded to Sketchfab, a 3D-modeling platform, and after a few minutes, you’ll be able to see the scan you’ve taken on the site.

Unfortunately, the two separate scans I took of my desk chair weren’t quite as good-looking as the chair Epic is featuring in its marketing:

I promise my chair doesn’t have a big hole in the middle.

I do sort of wish my chair floated, though.

A scan of my water bottle on a table didn’t turn out much better:

Feels like this water bottle wouldn’t work very well.

While my RealityScan models might look more like abstract art than believable 3D models, there could be any number of reasons why they weren’t up to par. Perhaps my iPhone 12 mini’s cameras aren’t good enough. Maybe I wasn’t in a well-lit room. I may not have taken enough scans or didn’t get the correct angles. And the app is launching in a limited beta, so Epic will presumably continue to iterate up to the app’s official release.

I still think the app has a lot of promise, as it could be a really useful tool to quickly create 3D models using just your smartphone. An early access release on iOS is set for spring, and an Android version of the app is set to be released later this year.

And this isn’t the only developer tool news we’ll get from Epic this week; the company is hosting a “State of Unreal” event on Tuesday, April 5th, at 11AM ET.

FCC approves broadband 'nutrition labels' to help you shop for internet

The FCC is pushing nutrition labels for internet providers. What you need to know The FCC has voted to move forward with new rules for ISPs to display nutrition labels. The proposed rulemaking would mandate ISPs to display relevant speed and pricing information to consumers. This should make it easier for consumers to make an informed decision on their broadband. The FCC voted unanimously on a plan that would allow consumers to make better decisions about their broadband internet. The proposal will require internet service providers (ISPs) - including many of the best wireless carriers in the U.S. — to display "nutrition labels" that display relevant service information for consumers at point-of-sale. This includes internet speeds, allowances, and clear information on rates. "If you walk into any grocery store and pull boxes of cereal from the shelves, you can easily compare calories and carbohydrates," FCC Chair Jessica Rosenworcel said in a statemen

Yandex spins out self-driving car unit from its Uber JV, invests $150M into newco

Self-driving cars are still many years away from becoming a ubiquitous reality, but today one of the bigger efforts to build and develop them is taking a significant step out as part of its strategy to be at the forefront for when they do. Yandex — the publicly-traded Russian tech giant that started as a search engine but has expanded into a number of other, related areas (similar to US counterpart Google) — today announced that it is spinning out its self-driving car unit from MLU BV — a ride-hailing and food delivery joint venture it operates in partnership with Uber. The move comes amid reports that Yandex and Uber were eyeing up an IPO for MLU  last year. At the time, the JV was estimated to be valued at around $7.7 billion. It’s not clear how those plans will have been impacted in recent months, with COVID-19 putting huge pressure on ride-hailing and food-delivery businesses globally, and IPOs generally down compared to a year ago. In that context, spinning out the unit could

Slack’s new integration deal with AWS could also be about tweaking Microsoft

Slack and Amazon announced a big integration late yesterday afternoon. As part of the deal, Slack will use Amazon Chime for its call feature, while reiterating its commitment to use AWS as its preferred cloud provider to run its infrastructure. At the same time, AWS has agreed to use Slack for internal communications. Make no mistake, this is a big deal as the SaaS communications tool increases its ties with AWS, but this agreement could also be about slighting Microsoft and its rival Teams product by making a deal with a cloud rival. In the past Slack CEO Stewart Butterfield has had choice words for Microsoft saying the Redmond technology giant sees his company as an “existential threat.” Whether that’s true or not — Teams is but one piece of a huge technology company — it’s impossible not to look at the deal in this context. Aligning more deeply with AWS sends a message to Microsoft, whose Azure infrastructure services compete with AWS. Butterfield didn’t say that of course
