Vircadia Reviews

  1. Most flexible Metaverse out there...

    Most of the 3D world experiences limit what a user can build and do. This is not so with Vircadia. The Apache license makes this 3D application the most flexible tool for building custom and interactive worlds. Vircadia is truly free, open and relatively easy to use. There are several developers who are working and improving this platform daily! Free content ensures that new users have access to materials for building their world without having to worry about learning difficult 3D applications. I highly recommend Vircadia and believe this will be the next big server technology on the world wide web.

    👍 Pros:    Spacial audio|Apache license|Inworld creation tools|Multiple platforms|Vr ready|Free content
    👎 Cons:    In development
  2. Probably the best open-source metaverse

    🏁 Competitors: VRChat
    👍 Pros:    Open-source|Running on linux
    👎 Cons:    A little buggy

    I'd heard about one, but it looks like they shut down a couple months ago: https://altvr.com/. Source: 11 months ago
  • R.I.P. AltspaceVR I will miss you
    I know a lot of you probably do not care that AltspaceVR is going away in March but I will miss it dearly. Sauce : https://altvr.com/ I was on the platform at the very beginning using an opendive 3D printed DIY headset my phone and trinus. I then made the switch to GearVR in 2017 and had great fun playing cards against humanity until they ended mobile support. I still visited occasionally the past few years on...

  • Microsoft is shutting down its metaverse
    For those who are unaware of the Microsoft metaverse, it is called AltSpace (altvr.com) and it was pretty much one of the most successful VR metaverses around until Microsoft bought it in 2017. Source: over 1 year ago

  • So you want to run a virtual event
    One specific sub-flavor of this sort of chat tool you might encounter are VR spaces like AltSpace, VRChat, or Mozilla Hubs that are primarily focused on VR but also usually support flat displays or smartphones. - Source: dev.to / about 2 years ago

  • FLAC 1.3.4
    Not pre-baked. I work on https://vircadia.com/ -- it has to give every user their own audio mix to account for their 3D position. This means codec costs add up fast. You can't just encode once and stream the same thing to a dozen people. - Source: Hacker News / about 2 years ago
  • FLAC 1.3.4
    Both, primarily the first. Low latency is definitely a requirement, but no issues with Opus on that account. > I haven't looked into how expensive it is to encode in terms of CPU time, so I assume maybe you're taking about a bottleneck in terms of the number of simultaneous streams you can support on a single CPU? Yup! I work on https://vircadia.com/ -- we have to compress audio in real time and every user gets... - Source: Hacker News / about 2 years ago
  • When the Stagnation Goes Virtual
    Second Life improved avatars by quite a lot in fairly recent times. There's also alternatives to it, eg, check out the project I work on: https://vircadia.com/ It's a sort of spiritual successor to Second Life, since it was started by the same guy -- Philip Rosedale -- after he left SL. It didn't quite work, so the commercial project died and got picked up by open source forks, which is what I work on. It's less... - Source: Hacker News / about 2 years ago
  • When the Stagnation Goes Virtual
    To me it's useful/entertaining in the ways forums and chats are, plus some additional features on top of that. Eg, you can talk to people, but in addition to that you have a collaborative 3D environment with positional audio where you can script, make games or do other stuff. Recently a group using our project put up a Christmas Carol VR play, and the results were most impressive. https://vircadia.com/ -- it's an... - Source: Hacker News / about 2 years ago
