Mesh Processing

We are working on various mesh and surface processing techniques as detailed below.

  • LiLit. Lilit is a software package for visualising functionals on free-form surfaces.
  • Mesh Filtering. There are many areas of scientific data processing in which the data is non-uniformly distributed. Beyond resampling the data to a regular grid there are currently few techniques for processing such data. This project aims to develop a general framework for processing irregular mesh data that copes with problems such as points having different numb...
  • Reliefs. Complex decorative reliefs are often added to CAD models in such application areas as sign-making, packaging, and ceramics to make product designs more interesting, more characteristic of the company, or of higher intrinsic value. New reliefs can be created from 2D artwork using software such as Delcam's ArtCAM, or can be hand-crafted, typically on...
  • Smoothing Boundary Curves. Many CAD/CAM processes utilise algorithmically generated boundary curves for a variety of purposes. For example, milling applications often use boundary curves to limit regions where a cutter may go, die design utilizes boundary curves to define parting lines on the object, and reverse engineering utilises boundary curves to segment the surface. Ho...
  • Watermarking Meshes. With the development of the Internet, digital media including audio, video, image and 3D shapes, can be copied and distributed easily. Often owners of the data wish to distribute it to some extend, but would either like to limit the distribution only to authorised persons or ensure that they can be clearly identified as the owner to avoid unauthori...
  • Watermarking

    A suitable watermarking scheme has to be sufficiently reliable such that it is feasible to use it as a mean to resolve disputes over ownership or origin of a particular object in the context of a court of law or similar situations. It should be infeasible to remove the watermark from the object on purpose ...
