Workshops

The programme of BDVA’15 will include four exciting hands-on workshops on 22nd September 2015. There will be two parallel sessions in the morning and in the afternoon.

Dynamic Visualisation of Scientific Workflows with Workspace (Matt Bolger)

Abstract

Workspace, developed by the Computational Modelling and Simulation Group in CSIRO, is a powerful, cross-platform scientific application framework and workflow editor in which you can construct scientific workflows, reusable software components and complete applications quickly and easily. Workspace features out-of-the-box support for tasks like mesh processing, interactive 3D visualisation, volume rendering, plotting, provenance, networking and database access and can be easily extended through plugins. This plugin support makes Workspace the perfect glue for combining components that utilise existing frameworks and languages such as OpenCV, NetCDF, GDAL, PCL, C++, OpenCL, Fortran, Python, R and JavaScript.

This hands-on half day workshop will get participants up and running with Workspace, provide a taste of developing their own workflows (including inline 3D visualisation) and outline how users and developers can continue to learn more through the tutorials and wizards included.

Communicating Science with Animations (Christopher Hammang)

Abstract
Many important biological interactions occur at the “mesoscopic” scale (the range between the size of atoms to cells), which is hard to capture through medical imaging. Animation can be a powerful and engaging way for scientists to communicate their work by visualising the structures and dynamics of biological phenomena. At the same time, the tools to produce animations are becoming increasingly accessible to scientists. The open source and free program Blender has seen dramatic improvements in recent years and is now being used extensively for scientific communication. Learn the basics of animating biological processes in Blender (software you already own) in this introductory course. This course will focus on getting users over the initial challenges of using animation software, as well as a guide to some of the concepts that should be considered when producing scientific visualisations.

His work has been featured on Australian national broadcast (ABC Catalyst) and was exhibited at the University of New South Wales galleries 2014 “Body Image” exhibit. His work has received international recognition, winning first prize at the 2013 VIZBI “Art and Biology” contest and achieving a top ten position in the Science Journal’s international visualisation contest “The Vizzies”. Christopher has produced work for many internationally recognised organisations, including CSIRO, Garvan Institute of Medical Research and the Nature Biotechnology Journal.

Multi-Dimensional Data Visualisation with Parallel Coordinates (Julian Heinrich, Timos Kipouros & Alfred Inselberg)

Abstract
In this workshop, participants will learn how to use parallel coordinates for the visualisation and analysis of multi-dimensional data. We will briefly discuss the basic geometry of the parallel-coordinate system, learn how to read the resulting visual patterns, and investigate some of the most important interaction techniques to find these patterns. We will demonstrate how to use parallel coordinates for the analysis of engineering optimisation data, and how to support the decision making progress. Participants will also have the opportunity to create parallel-coordinate visualisations of their own data using tools such as R or javascript. If you want to join the hands-on parts of the workshop, please bring your own laptop. A description of the required data format will be made available soon.
Due to the large number of participants we will not be able to allocate much time on the hands-on part of the workshop. However, we invite you to bring your laptop as we will be pointing to some online resources that you might find useful. Note that we can not guarantee for power supplies.

High-performance Visualisation Using OpenGL/WebGL (Tomasz Bednarz, Daniel Filonik, Xavier Ho)

Abstract
In modern data science, accelerated visualisation techniques are required to explore data sets in a robust way. This workshop will provide introduction to OpenGL, which is the most widely adopted 2D and 3D graphics API in the industry, bringing thousands of applications to a wide variety of computer platforms. In addition, it talks to compute platforms such as OpenCL or CUDA, and enables developers/scientists to create high-performance, visually compelling graphics software applications. The workshop will include introductions and hands-on exercises to basic concepts of hardware rendered graphics, shader language and also web based version of OpenGL, called WebGL. Short introductions to OpenCL and new Vulkan APIs will be also showcased.
