Geometric computing and graphics

Our group explores the design, capture, analysis and optimisation of 3D models and data, and their applications in computer graphics and other domains.

We live in a three-dimensional world. Modelling and processing 3D information is an important task in computer graphics and many other fields such as science, engineering, and architecture. The group works on fundamental techniques for 3D geometry processing including acquisition, registration, segmentation, optimisation, as well their real-world applications.  

The group collaborates with the Welsh School of Architecture on the research and education of Computational Methods in Architecture.


  • Attracting PhD students and research funding
  • Facilitating cooperation with research groups and organisations outside the School of Computer Science and Informatics


Our research deals with two broad areas:

3D modelling and geometry processing techniques:

  • 3D acquisition
  • 3D reconstruction
  • surface parameterisation
  • shape registration
  • shape analysis
  • 3D shape retrieval and indexing
  • data-driven modelling
  • procedural generation
  • numerical optimisation
  • mesh processing.

Applications of geometric computing:

  • 3D printing
  • CNC machining
  • virtual and augmented reality
  • reverse engineering
  • robotics
  • architectural design
  • computer animation.
