AltspaceVR
why we work on the VR web
our service
communicate with anyone on the planet in the most natural and fufilling way possible
many platforms
operating systems
headsets
many devices
controllers
body sensors
many people
over 167 countries represented
live events have audiences in the thousands
widespread access to high-quality VR
active developer community
diverse languages, interests, and skillsets
be together
do things together
people want information, applications, and games
in VR, people can
- meet
- discuss
- laugh
- attend
but they want more
they want the web
across all platforms, instantly, and safely
How can we make this happen?

Three.js Renderer
-
Three.js is renderer agnostic
-
We wrote our own renderer
-
Converts the three.js scene graph to Unity objects
-
Supports a performant subset of materials
Javascript APIs
getUser()
// public information about the user
// useful for nameplates / highscores
getSpace()
// information about the space
// useful for persistence
getEnclosure()
// enclosure dimensions and scaling
// useful for reactive VR design-
Normal A-Frame components
