The Blender / FreeCAD communities might bite.

Was thinking what GitHub does to preview STLs. I'm assuming WebGL with glTF exported... Meaning am ElectronJS app in transparent mode code render a 3D thing like a part to be 3D printed.

Yes! Some desktop 'widgets' that show 3d content from various forms.

I wouldn't go as far as fsv[1] but some basic in-environment vis is called for.

That would be so, so cool. I don't see this happening for a while unless a CAD vendor works with us but definitely where I see this tech.

How about 3D modeling with something like Blender? BTW, the key to making stuff like that work well isn't just the UI affordances, but latency. Head tracking, room tracking, video passthrough for AR, all highly sensitive to latency. You can see the effect even in the GIFs on your landing page: in the AR mode the floating windows slightly lag the external view when the user moves their head. Latency is what makes many…

There are tools for latency measurement for VR applications. Before FB acquired them, Oculus had one for $99. But jitter's just as bad as latency. That usually required some thinking to work on.

I just want to comment that, my interest in a VR headset is precisely for standard terminal-based editing, except that now the focal point is at infinity and my eyes can relax better. That might be an underappreciated draw. Consider seeing if that holds and including that as a use case. You'd have +1 consumers here and I cannot be alone.

The focal point in our headset is on the order of ~2m. Infinite conjugate adds significant difficulty and basically nobody does this (we tried in our first iteration). But 2m is comfortably far, imo

Yeah, that's so much better than the 1m for 14 hrs/day I get here at home.

> VR is in my opinion a success if it becomes normal but no one really uses it day to day. I think pretty much all the members of my family regularly play games in VR (on their own headsets). > But as something central like I imagined the metaverse or what ready player one proposed? We don’t actually want that. That movie was supposed to display something dystopian. Meta is something dystopian.

Heh. My personal take on Facebook's Metaverse[1] is that it jams the entire framing of VR computing through the prism of "social network", which causes all kinds of poor product focus and misaligned incentives. With that said, I personally don't mind Meta selling Quest units at a loss. It's been a net good for the ecosystem (IMO), and has exposed a lot of people to VR who wouldn't be able to afford a headset otherwis…

It's mostly just a shitty version of VRChat with people you don't like.

This looks like a decent deal looking deeper into it. Things that weren't obvious on first pass: (1) The VR specs are much higher than consumer level. I suspect this is what makes it reasonable to read text on it. The comparison headset is this: https://varjo.com/products/aero/ (They named it, but didn't google it) (2) They said "VR Computer" but don't define the term. They mean that it's a full PC with a headset ins…

Upvoted for the excellent feedback. 1. We'll do a better job defining the term "VR Computer" in our sales page. 2. We'll consider adding a keyboard/mouse as optional add-ons. We have thought about including a "keyboard apron" as an item add-on that is actually differentiated from other keyboards, and one that would be particularly useful for VR computing (with the added freedom of movement).[1] Would something like t…

First, congrats on all the progress you've made. I've been part of your mailing list and watching from the sidelines for a while. I really do hope you succeed, and i love the idea, i just don't have the spare cash to pre-order.

> At a high level, SimulaOS is going to be NixOS + our VR window manager.

I don't know all the technical details about Nix and the various VR development SDK/tools available, but when i see something like "it'll use NixOS" when i know NixOS is very opinionated and unique in how one uses it and develops for it, i immediately assume that it is 100% is some engineer on the team's tech pet project technology, and not necessarily the best tool for the job.

Is there any reason to use it over eg. Debian/Ubuntu/etc that has a lot more use and people are more familiar with tweaking and developing for it?

It used to be that companies had products ready for sale before trying to sell them. Generally with production being funded by a loan. Is this something that’s just impossible now? Or banks don’t want to fund something like this?

Bank debtors are very downside oriented, and want to see a conservative track record of cash flow coming into a business before they are willing to go anywhere near it. (Not necessarily saying this is always bad).

Venture is a better fit for our project, but from the outside we look like we're way too niche to ever have a big market. Great VCs will know that small markets can turn into large markets[1], but we had a very hard time finding good investors in the past. We tried to raise money from traditional institutions and failed, and decided that the best way to proceed was to just focus on our product and carve our own path.

The software side does; there's videos of George working on Simula in Simula. Trickier for the EE/ME side as it's all Windows.

RE weight: we're targeting 800g (balanced evenly between front headset/rear compute pack).[1] This shouldn't be more straining than a Valve Index. RE battery: our target is 3 hrs (for reference: the Quest has a 2-3 hour battery life). Here's the link David was referring to: https://youtu.be/FWLuwG91HnI . It shows me dog-fooding Simula's software on the HTC Vive. [1] This is still a preliminary number, which might cha…

The Quest doesn't have a 2-3 hour battery life if you're doing anything past staring at the welcome lobby. A bit over an hour for most applications is standard. Source: I am VP Eng of ForeVR Games, we make games for the Quest

I would be tempted by this if I could try out SimulaVR first using my HP Reverb G2 HMD. It has great resolution, but I don't think there is a Linux driver that I guess would be the pre-requisite? I know a lot of people into VR for flight sims and driving, that spend $2000+ for high resolution VR experiences, so that demographic could be a good cross-over with this sort of productivity set-up - as long as they can try…

Some support for WMR headsets is available in https://github.com/OpenHMD/OpenHMD but without 6DoF / inside-out controller tracking so far.

Man, what has HAPPENED to this place? I'm the biggest curmudgeon in the room, I'll have six feet of dirt on my face before I agree to use this daily, but damn, folks, this IS cool. Everyone complains about boring stagnating consumer tech, locked-down hardware, and Mark Zuckerberg making a real go at personally stalking every single person on the planet - this is the _exact opposite of that_. This is high-end, incredi…

Yeah - as an ancient software geek I don't want it, but I definitely want someone to build it, especially in the open source space.
