Retrired (Emeritus) professor of computing science. I’ve wprked with
VTK since mid 90s. Firstly in exploiting it fot graph visualization using exensions that mirrored the work of Sandia that became incorporated into the toolkt. Later I worked on Multifield Topological Analysis, in paricular eork on the JointContour Net with Hamish Carr that was used for a number of substantial case studies.I’ve also done more exotic work. Using Haskell for vis - exploiting lazy evaluation; initial work on anontology for visualization.
