Morning session:
Afternoon:
2/ Looking at the tech stack for #WebXR (interesting to see watches included in the discussion of WebXR) + the schedule for the day for the WebXR Developer Summit.
3/ @mrdoob have a bit of history & context in the evolution of @threejs, and then answered some questions about the most popular, open source graphics library on the web.
4/ @DePanther is talking about using exporting WebXR from Unity. There's a number of different exporters, including one he maintains:
github.com/De-Panther/uni…

Downsides to this approach are build size + download times, testing iteration times & can't use all aspects of Unity yet.
5/ More from @DePanther on which WebXR APIs are supported in the Unity WebXR Export + what's coming next.
6/ @DePanther recommends doing smaller gamejam projects to start with WebXR from Unity.
He listed a bunch of WebXR examples exported from Unity:
msub2.github.io/silk-brush/
drone.sectortech.app
prefontalcortex.de/en/projects/di…
needle.tools
worldsdemolisher.totalviz.com
7/ @samsunginternet's @AdaRoseCannon moderating "All-In-One Workflow" panel featuring @stew_rtsmith of #AmazonSumerian (and handy.js), @willeastcott of @playcanvas, & Jonathan Hale of Wonderland @WebXREngine.
Featuring some of the benefits & challenges WebXR frameworks.
8/ Three Google engineers @cwilso, @DaKangz, & @Tojiro talking Low-Level APIs like #WebGPU.
More info: webgpu.io
It'll be leveraged by higher-level frameworks like @threejs & @aframevr.
Shout out to extensiblewebmanifesto.org
Risks of fingerprinting via WebXR APIs
9/ @MetaVRse engine demo by CTO @walida16 publishing WebXR scenes for both AR & VR without needing to know any code.

12/ Covering the main features of #WebXR including the core that replaced WebVR.
AR Module to show WebXR scenes on top of passthrough camera or transparent display.
Gamepads to get access to input controllers
13/ Other main #WebXR features include Hit Test raycasting to select virtual objects, DOM Overlays on top of graphics (for handheld phone-based AR devices only), Layers for static images, video, or WebRTC content in WebXR (layers may have DOM content in future), & hand input.
14/ A look at some of the future #WebXR features in development. These features may or may not ever land, & they're soliciting feedback & user interest.
Light estimation: github.com/immersive-web/…
Depth Sensing: github.com/immersive-web/…

[Me: The Oculus Browser team has been doing an amazing job at rapidly iterating]
Progression of Immersive Web development ecosystem (we're likely between emerging & capable phases).

1/ THREAD covering a #NeuroRights gathering co-sponsored by @FBRealityLabs & @Columbia_NTC's @neuro_rights called "Noninvasive Neural Interfaces: Ethical Considerations Conference."
They'll be Looking at the ethical implications of XR technologies from neuroscience POV. ImageImageImageImage
2/ Here's the #NeuroEthics Humans Rights Framework by @yusterafa, @JaredGenser, & @SRHerrm published in March:
3/ The @FBRealityLabs Co-organizers are Stephanie Naufel (@snaufel) & Carlos Hernández (@cxhrndz)

I'm really glad to see Facebook catalyzing these conversations between ethicists, academics, and the bleeding edge of industry.

I'm watching #Vivecon, where @htcvive is announcing 2 new VR HMDs (embargo lifted at 9a).
@RtoVR has specs on the Vive Focus 3, enterprise-oriented, $1,300 price, 120° FoV, new controllers, (2,448 x 2,448) per-eye, swappable battery.
roadtovr.com/htc-vive-focus…
2/ @Htcvive's single one-off cost of $1300 for Vive Focus 3 is interesting since Oculus Quest 2 for Business is $799, but I believe Facebook requires some additional recurring subscription requirements for their Workplace for Facebook & perhaps more.
3/ Vive Business was announced at #Vivecon.
New app Vive Sync was added to their Vive XR Suite.
New Vive Business App Store to sell enterprise XR apps.
New Vive Business Device Management System.
[A number of these do have subscription options, bringing parity to Oculus]

1/ Here's the 7 amazing @VRChat worlds that @LakuzaVR took the @NoProscenium SPRING FLING to on the PCVR World Hop.

We same in the virtual water & rode a turtle at the bottom on the ocean in DEEP BLUE by @VRCFins
vrchat.com/home/world/wrl…

2/ @LakuzaVR started us on THE EDGE by Mochie, which is a creative coding/shader world impeccably timed to the music.
vrchat.com/home/world/wrl…
3/ TREEHOUSE IN THE SHADE by @1001vrchat and SCRN is one of my favorite @VRChat worlds.
It's got the most impressive array of worldscale shader effects that transport you to MANY different realities. Play w/ the controls, but also let someone else drive.

1/ What's so unsettling about happened on Wednesday is it marks the beginning of a new cycle of violence, & not the end. This is the physical manifestation of @johnrobb's concept of "Networked Tribalism" on the right, & I expect it to continue in 2021.🧵👇
2/ These two images from the attempted insurrection contrast the maturity of tactical sophistication vs a more harmless tourism of sedition. Whether you fall onto on side or the other, then @johnrobb says lessons will be learned from this first iteration.
3/ I doubt there was really a master plan for what to do once they got inside. But there's probably a lot of foreign adversaries who were watching who no doubt got a lot of ideas about how this movement could be exploited for the benefit of their country.

FTC + 48 states are suing Facebook:
"The FTC alleges that Facebook engaged in a systematic strategy to eliminate threats to its monopoly, including the 2012 & 2014 acquisitions of Instagram & WhatsApp"

Some of these behaviors may be still happening in VR.
cnbc.com/2020/12/09/ftc…
The FTC lawsuit focuses on Whatsapp & Instagram, but Bloomberg reported on December 3rd that the Justice department has also been talking to a number of VR developers, who are also alleging similar anti-competitive behaviors within the VR industry.
bloomberg.com/news/articles/…
3/ On August 18th, Oculus announced that Facebook social media accounts would be required to use their VR hardware, and there was a backlash that catalyzed VR developers like @BigscreenVR's @DShankar to speak up about potential anti-competitive behaviors:
