Compressing 3D Data For Online Computer Games

Case Study: Delivering high quality 3D graphics to a web browser in real time

A current challenge in online computer gaming is how to transmit data-hungry 3D images using existing broadband networks. Is it possible to maintain realistic levels of detail while reducing the quanity of data required?

The new techniques we developed during this project have resulted in two European patents and a spin-off company with venture funding.


To demonstrate that geometric data in computer games can be efficiently compressed and rendered using mathematical functions based on solutions to Partial Differential Equations (PDEs).


Enterprise Ventures Ltd.


Based on patented work, Enterprise Ventures invited us to demonstrate that existing geometric game data can be efficiently compressed. This was part of a feasibility study and due diligence to identify if the patented technology has potential for a future market product.

The problem is that current approaches for representing complex 3D models are not well suited for use in web browser applications. They either require significant bandwidth to download a detailed 3D object, or sacrifice detail to enhance response speed for the end user. Although internet bandwidth is slowly increasing, a software approach could make data distribution easier for a wide range of industries.


The techniques developed through this project allow the actual game content to be compressed by 90% compared to existing techniques.

The project resulted in a spin-out company, Tangentix Ltd, which has so far received two rounds of funding from Rising Stars and South Yorkshire Investment Fund.
