visionOS 2 PortalComponent: A more anticipated teleportation artifact

Keywords: Portal, visionOS

In this article , Puffinwalker introduced us to the use of the new features of PortalComponent in visionOS 2, and made a very cute super dream with PortalComponent, worth reading.

News

Meta Quest v69 released

Keywords: Quest, Meta

In the past week, Meta officially released Quest v69 , in this update, the more interesting are these features:

• Seamless multitasking: Simply put, when you were using Quest before, if you were playing a game and wanted to open an Android-like application floating window, you had to exit the game and come back. The updated Seamless multitasking allows you to use the Home button to display the multitasking panel that existed before, and can hold up to three applications, including the browser. This feature is greatly beneficial for games that need to check the strategy to play (such as various lost black myths, Wukong 🐒), or some slow-paced games. Watch some videos at the same time (like in the 👆 picture)
• Meta AI adds Hey Meta wake-up word: a more common update, before this Meta AI can only be awakened by double-clicking the Meta button on the handle or clicking on the system menu, but Meta AI This function itself is only available in the US and Canada.
• Window supports Spatial Audio : Simply put, the audio played in the flat window application in Quest also supports Spatial Audio, and the sound you hear will be more spatial

Unity no longer charges runtime fees

Keywords: Unity, Runtime Fee

The Unity runtime fee controversy, which began in September 2023, finally settled in September 2024, one year later: the new CEO Matt Bromberg announced that Unity will cancel runtime fees .

Tips

About the runtime cost of Unity, we have mentioned it in Newsletter 009 and Newsletter 010 .

If you are not familiar with this matter, it can be simply understood that Unity required all users of Unity to charge additional fees based on the number of installed users of the game in addition to the original fees in September last year. This move has caused strong dissatisfaction among industry developers. Former Unity CEO John Riccitiello resigned as CEO because of this matter, and Matt Bromberg took office in May 2024.

Along with the cancellation of runtime fees, Unity Personal has raised its fee threshold (from $100,000 to $200,000), and Unity Pro and Unity Enterprise have increased their subscription prices (by 8% and 25% respectively). Overall, Unity’s strategy is friendly to small and medium-sized developers and raises prices for large customers to reduce its losses (yes, Unity has not yet achieved profitability since its launch).

Unreal now supports perspective mode on visionOS

Keywords: Unreal, visionOS, Passthrough

Although there are still some rough edges and imperfections, according to this X , Unreal can finally show the real world on visionOS 2!

Article

Using visionOS to revolutionize surgery and medical treatment

Keywords: visionOS, Surgery, Medical

In this article , the author proposes the following viewpoint: before spatial computing, 2D plane CT and MRI scans have brought better tools for surgeons’ surgeries, allowing them to more accurately understand the internal structure of patients. Vision Pro only requires hand interaction and fine rendering of 3D objects, undoubtedly giving surgeons a more capable assistant on the operating table.

In addition, the author also lists and discusses a series of medical-oriented apps currently available on Apple Vision Pro, such as:

• INSIGHT HEART : an immersive view of the structure of the human heart
• Fundamental Surgery : Immersive surgical training simulation

App

AquaZen: Immerse yourself in the tranquility of water

Keywords: Apple Vision Pro, Zen, Zen

AquaZen is an app that can provide an immersive aquarium experience. It provides three modes internally: 360 ° Aquarium, Space Aquarium, and Shared Space .

In the 360 ° aquarium, you can watch various sea fish swimming around you in a panoramic underwater world, and the app also provides configuration options for you to choose which fish to display in the current scene.

In the space aquarium, these fish no longer swim in the vast and boundless water, but in the room next to you. Obviously, the scene perception ability of visionOS is used here. If you are in a very small room, you will find these fish swimming very “crowded” in the small room.

In the shared space, you can place the aquarium in the form of an aquarium, like a decoration, next to you. Similarly, you can also configure all the displayed fish here.

Next, let’s talk about this application from the perspectives of user requests, product solutions, and Technology Implementation.

From the user request, AquaZen intends to solve the user with Apple Vision Pro, find a different environment and then change the mood of the needs, such applications on the App Store is not few, the official, meditation applications, Healium , Endel are intended to solve this kind of problem.

From the product plan, AquaZen uses a solution surrounded by swimming fish. Unlike the previously mentioned applications, the fish in AquaZen swim under certain rules and are not completely preset scenes. Therefore, compared to seeing the same video or audio every time, the threshold for visual fatigue for users will be slightly higher.

From Technology Implementation, the most interesting technology applied in the entire application should be how to make these fish swim. In this regard, Apple has a Demo: Building an Immersive Experience with RealityKit on the iOS.
