About The Opportunity:

Next-generation computer graphics technology, including ray tracing, a technology that describes how to identify the intersection between a line of sight and a three-dimensional surface in a more efficient manner, and a photon mapping invention that describes a technology to reduce errors in the reconstruction of the lighting using virtual photons in a graphical image, have been developed at Swansea University. The ray tracing technology allows faster image processing with less usage of power and is ideal for mobile applications. The photon mapping technology allows for dramatically more realistic images with fewer photons in the estimate, thereby speeding up rendering time.


  • The graphics accelerator is particularly suitable for mobile applications and the photon mapping technology can be applied to any general application where efficient, realistic images are required.

Key Benefits - Graphics Accelerator:

  • Identifies intersection between a line of sight and a 3D surface in a more efficient manner;
  • Faster and more efficient power processing and therefore suitable for mobile applications;
  • Availability of algorithm in a format compatible with OpenGL or DirectX;

Key Benefits - Photon Mapping:

  • Produces dramatically more realistic images with fewer photons in the estimate, and therefore speeds up rendering time, and greatly reduces blurring and noise;
  • Reduces memory overhead since scenes can be rendered using fewer stored photons.


IP Status:

The technologies are claimed under patent application nos PCT/EP2009/059618, US 13/354578 and PCT/EP2010/015998.
