Microsoft’s recently acquired virtual reality community, AltspaceVR, has announced a Developer Portal to enable developers to use their SDK to create holographic, multi-user web apps and experiences for virtual reality.

The AltspaceVR SDK can be used together with three.js and other javascript libraries to create a variety of content that can be experienced with consumer VR hardware like the Oculus Rift or HTC Vive.

A bit like Second Life, AltspaceVR is a social platform for virtual reality.

The service brings people together in virtual reality from over 160 countries to attend meetups, comedy shows, yoga classes, dance parties, and large-scale events hosted by NBC, Reggie Watts, Justin Roiland, Drew Carey and more.

Microsoft has said they intend to use the service to help build the world’s preeminent mixed reality community.
