Following the basic project setup of the first part of this article, we now get to the fascinating details of the ARCore SDK. Learn how to find and visualize planes. Additionally, I’ll show how to instantiate objects and how to anchor them to the real world using Unity.
ARCore by Google is still in preview and only runs on a select few phones including the Google Pixel 2. In this article, I’m creating a demo app for ARCore using the ARCore SDK for Unity (Preview 1).
It’s following up on the blog post series where I segmented a 3D model of the brain from an MRI image. Instead of following these steps, you can download the final model used in this article for free from Google Poly.
In the first part of the article, we captured a 360° photo using a Samsung Gear 360 camera. Now, we’ll create a new Unity project for Android. Using the right shader and material, we can assign the cylindric projection to a Skybox. This is the perfect 360° photo viewer for Unity, which can then be easily deployed to a Google Daydream / Cardboard VR headset!
Loading the 360° Photo in Unity
The Skybox in Unity is the easiest way to show a 360° photo in VR. Note that 360° 2D and 3D video will be supported out-of-the-box in the upcoming Unity 2017.3 release, according to the current Unity roadmap.
With the first Bluetooth 5 devices just released (first and foremost the Samsung Galaxy S8), Bluetooth Beacons like Apple iBeacon and Eddystone by Google gain a lot of potential. Increased range means future beacons will cover a much larger area, without increased power consumption. With the payload increase of beacon advertisement frames from 31 bytes to 255 bytes, the amount of information transmitted by beacons can substantially increase.
In my session about Bluetooth Beacons at the Mobile Developer After-Work #14: Creating Immersive Environments, I provided a short update about the latest news. Unfortunately, recording of the live session at the event failed. Therefore, I’ve re-recorded it – you will miss the live experience, but I did have a little more time for more detailed explanations of some important facts, so it’s well worth watching again even if you have been at the #mdaw14 Event!
The blog post from Google sounds intriguing – 20% to 30% better JPEG image compression at the same visual quality through the Guetzli encoder. That has potential for a huge speed increase of websites.
While there are of course a lot of other better image formats around than JPEG (e.g., WebP or JPEG 2000), time has shown that it’s more or less impossible for them to gain any traction. It’s a pity, but on the other hand ensures that pretty much every device available on the market right now can load and show all websites.
