Frequently Asked Questions¶
Is this open source, free to use and share?¶
Yes, it's all free and open. Server and client code is published under Apache 2 license, all 3D models published by their respective authors under Creative Commons Attribution license.
Is there any documentation?¶
This is good place to start, this page links to all available resources.
How many users can share a “world/space” simultaneously?¶
By default, number of users per space is not limited. There is a server parameter to limit that (org.vrspace.server.maxSessions) that can be specified either in config file or command line. Users that hit the limit remain in the queue for configurable timeout (org.vrspace.server.sessionStartTimeout, zero by default) until someone leaves. An error is raised on timeout.
Setting up development environment¶
Here's all you need to start development on Windows.
IDEs can work with github directly, but whatever you ask, you'll get a command line answer.
Command line git is simply a must have. Bash also includes a lot of goodies like ssh.
Java 8 will work, java 11 recommended. Get it either from Oracle or elsewhere, e.g. Zulu OpenJDK: https://www.azul.com/downloads/zulu-community/?package=jdk
Mind that IDE will complain if you installed unsupported version of Node; should that happen, remove Node, and install latest one supported.
Get it from https://nodejs.org/
Eclipse for Java developers (not enterprise), with Spring and Web plugins:
Download eclipse here: https://www.eclipse.org/
And then go to Help -> Eclipse Marketplace
Search and install Spring Tools 4 and Wild Web Developer plugins.
You'll also need to download and install https://projectlombok.org/
Once done, restart the eclipse.
Import and start the project¶
In Eclipse, you can use either default or new workspace for the project.
Assuming you have cloned the project from the github,
Go to File -> Open Projects From the Filesystem
Then choose vrspace directory.
This will import vrspace folders and project subfolders, click Finish.
In vrspace project folder, in src/main/java, there's org.vrspace.server.ServerApplication.java.
Open it, then right click on the code.
From the menu, choose either Run as or Debug as -> Spring Boot App.
Open http://localhost:8080/babylon/connect.html with two browsers, and navigate around.
That's all, you're all set!
HTTPS is required for pretty much everything - WebXR, camera, mic access.
By default, the server runs on 8080 port with plain HTTP. To enable HTTPS, edit application.properties (found in src/main/resources), and change following properties:
server.ssl.enabled=false # default port 8080 #server.port=8443
Apache reverse proxy setup, linux, windows, TBD
Docker and OpenVidu¶
OpenVidu voice/video chat server runs as docker image. This is only required for development of voice chat functions.
Local execution (development):
docker run -p 4443:4443 --rm -e OPENVIDU_SECRET=YOUR_SECRET -e DOMAIN_OR_PUBLIC_IP=YOUR_IP openvidu/openvidu-server-kms:2.17.0
Running on server:
Then either modify openvidu.publicurl and openvidu.secret in application.properties, or run server.jar with -Dopenvidu.publicurl=YOUR_URL and -Dopenvidu.secret=YOUR_SECRET
