3D visualization

• Make sense of large data sets

Technology for a better society

Big data

• Requires heavy processing

• But we want to be mobile!

Technology for a better society

Security

• Encrypted data!

• Evil maid attack • Cold boot attack • Stoned boot attack • + many more

Technology for a better society

What do we want

• Ability to visualise large data sets – Large processing power

• Access anywhere

– On any device

• Security

– Stop people from stealing our data

The Tinia Framework, a possible solution

• Developed by SINTEF Applied Mathematics as part of the CloudViz Project

• Keeps the data on the server

• Use the server hardware to do advanced visualization

• Displays only resulting image to the client

• Using HTML5, it works in modern browsers

The Tinia Framework

• Demo showing large model of chemical installation from

Technology for a better society

Security

• No data on client

• Ability to restrict access to the visualization server – VPN – Access through gateway server – SSL encrypted web page – Username / Password restricted access – Whatever else you want

• Open Source framework, Apache server module – Inspect source

• Does not solve how to secure server or transmission

Technology for a better society

Security breach

• Only gives access to resulting images – Underlying data is only on server

• Ability to blacklist client

• Restrict access to known IPs/Machines/Mac-addresses/other

Technology for a better society

Supported platforms

• Works on most any modern device – iOS, Android, Window, Linux, OS X

– iPad, iPhone, tablet, smartphone,

– Netbook, laptop, desktop, workstation

Technology for a better society

Demo

• Running on Amazon EC2 GPU instance

How is this different from Citrix or other solutions?

• Interactions handled on the client

• Supports local rendering of simplified geometry (client geometry) – Hides latency – Requires WebGL support

Technology for a better society

C++ framework

• Integrates with your existing visualization software – Requires source changes to software

• Desktop development environment – Full access to usual debugging tools!

• Change to server application by changing a handful code lines – Server runs only on linux
