Beyond the Visualisation Workshop

Thanks to Brian Corrie, the instructor, and the 23 UofS researchers who attended the Introduction to Visualisation Workshop last week, and who made the workshop a success.

For those unable to get into the workshop, the materials from the workshop are available on-line. This includes the powerpoint slides; exercise text; and data used.

There were a few people at the workshop who were interested in learning more and having more opportunities to play with Paraview, to learn more of its features and to explore other datasets. To help those people, and others that are interested, here are a few resources that might be of interest:

  • The Paraview Tutorial is a set of exercises and data intended to familiarise readers with the program. It covers some of the same features that Brian talked about in the workshop, but does show some different features.
  • Boston University’s Information Technology & Services team have prepared a web based tutorial that has a focus on vector visualisation, and includes example data.
  • Try Paraview with your own data. It can manipulate a number of file types and formats. Molecules expressed in the PDB (Protein DataBase) format can be read in with the “Protein Data Base files (VisIt)” filter. Files for 3d printers (STL files) can also be viewed with Paraview.

Paraview is based on the VTK (Visualisation Tool Kit), which has a number of features not directly available in Paraview. However, VTK filters can be added to Paraview as plug-ins.

Moving on after Paraview, your visualisations can be enriched through other programs. Here is an example of how to bring a Paraview visualisation into a ray tracing program (Blender) to do enhanced post processing effects.

If you have an interest in visualisation of your data, please send a note to Research Computing. And please follow this blog to catch our future posts on visualisation.

  1. There was a question about viewing PDB (Protein DataBase) files in Paraview at the workshop.

    I have found that when using these files, they are best opened with the “(VisIt)” reader.

  2. A further note:

    Brian mentioned the new version of Paraview (4.0) had been released the day before the seminar. Some of the new features of this version are being announced, and this one may be of interest to the seminar attendees (and others).

    Sections of data that are grouped together can now be shaded independently. This simplifies visualisation processes in cases where segmentation of your data gives “blocks” that are to be treated differently.

  3. A reminder for attendees – please fill in your surveys for the workshop. These are extremely important in helping us provide training in subjects like this, and for future workshops on visualisation.
