Introduction

IEC  Akraino Edge Stack supports AR/VR  applications. It could support AR/VR Algorithms that with GPU Modeling (i.e. modeling describes the process of forming the shape of an object) Compositing (e.g. Environmental Mapping, Tone Mapping) Rendering and Illumination Models Visualization of Large Volume 3D Models (e.g. Global Network Operations Center monitoring) Registration (e.g. Stitching data from distributed sources) Segmentation (e.g. Segmentation and detection for security monitoring). This IEC Type 4 AR/VR platform utilizes Tars for remote direct memory access control. In this document, we use Virtual Classroom  as demo for IEC Type4.   Virtual Classroom is an online learning environment that allows teachers and students to communicate and interact with each other in real time. We use WebGL, Three.js and JavaScript to develop Virtual Classroom application.

1. deployment
cd /opt
yum install docker-ce --nobest --allowerasing-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce docker-ce-cli containerd.io
systemctl enable --now docker
curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version

curl https://s3-eu-west-1.amazonaws.com/aws.openvidu.io/install_openvidu_2.13.0.sh | bash

2. Configuration
vi /opt/openvidu/.env

# add IP and admin PW
OPENVIDU_DOMAIN_OR_PUBLIC_IP= $your_host_IP

OPENVIDU_SECRET= $admin_PW

3. Execution
cd /opt/openvidu/
./openvidu start

Available services 
Consume OpenVidu REST API through https://$your_host_IP/
If the application is enabled, it will also be available at https://$your_host_IP/
You can open OpenVidu Dashboard to verify everything is working as expected at https://$your_host_IP/dashboard/ with credentials:
user: OPENVIDUAPP
pass: $admin_PW

4. Install Java for Jenkins Slave

For Slave Mode, install Java will be ok.

sudo yum install -y java-1.8.0-openjdk-devel

...

Virtual Classroom demo includes two parts: (1) server side and (2) client side. The technologies used to develop these applications includes WebGL, Three.js and JavaScript.

The code could be find at:

git clone https://github.com/OpenVidu/openvidu-vr.git

...

sed -i 's/demos.openvidu.io/${Local_IP_Address}/g' app.js

To execute:

docker run --rm --name openvidu_server -d -p 4443:4443 -e openvidu.secret=MY_SECRET -e openvidu.publicurl=https://${Local_IP_Address}:4443/ openvidu/openvidu-server-kms
