Data
NeCTAR Research Cloud Training
This training workshop will provide attendees with an introduction to the available NeCTAR Research Cloud resources at the Pawsey Supercomputing Centre. At the end of the workshop attendees should feel confident in applying and experimenting with this exciting new technology. The workshop will aim to provide an introduction to using the Infrastructure as a Sevice - IaaS capability of the NeCTAR Research Cloud.
The workshop will include:
- Introduction to the Unix shell.
- The NeCTAR Dashboard basics of key generation, configuration and launching a Cloud instance.
- Managing and Maintenance of your Cloud instance.
- Moving data to/from the Cloud.
- Introduction to git (time permitting).
Scientific Workflows on NeCTAR – An Introduction to SaaS
A hands-on workshop were we will work through the procedures of configuring a basic NeCTAR Cloud instance to be able to meet unique research requirements. Attendees are expected to have current NeCTAR projects.
- Using the package management tools.
- Efficiently handling your data with Volume Storage.
- Advanced scripting to automate workflows.
At the end of the workshop attendees should feel confident in modifying their instances and developing custom workflows with this exciting new technology.
Visualisation
3D printing and data visualisation: A technology brief
3D printing is an exciting technology whereby a digital representation of data is converted into a physical object that can be held and explored in the same way as we normally study physical objects in everyday life. The technology has been around for some time in the engineering disciplines where it is generally referred to as Rapid Prototyping. Developments in more recent time have removed some of the previous limitations, which in turn have created a range of new application areas.
This seminar will present how 3D printing may be employed as part of the visualisation process, both as a way of studying datasets as well as conveying a sense of that data in teaching and public outreach. As an attendee of this seminar you will gain an appreciation of the current state of the technology, it’s strengths, and it’s limitations.
You will be equipped to judge when 3D printing may be an appropriate means of visualising data, and how to go about creating optimal digital models. You will also see a number of examples of the use of 3D printing from researchers in various diverse fields such as medicine, geology, mathematics and archaeology.
Content Creation for Dome Displays. Part 1
Please accept our invitation to the the presentation 'Content creation for dome displays'. Domes are an exciting way of surrounding the viewer in a digital environment, filling their entire visual field of view. This introduction to dome displays will provide a comprehensive overview of the advantages and challenges of creating content for this particular style of immersive environment. Unlike flat single surface displays or multiple wall displays there are some fundamental differences when it comes creating content for smooth hemispherical surfaces. The seminar will draw upon the presenter's extensive experience of using a range of hemispherical dome configurations, these include large scale planetarium-orientated domes to the small personal front facing iDomes. Content will include photography, fisheye and 360 degree video, realtime applications and simulators using game engines.
Application examples will cover science visualisation across a number of fields, education and public outreach through exhibitions in museums or art galleries. At the end of this seminar the audience should understand the opportunities and requirements for creating content for a dome environment.
Content Creation for Dome Displays. Part 2 - Technology Workshop
This workshop is a follow-up to the one hour Content Creation seminar run by Paul Bourke at the HIVE in June. Dome displays have unique characteristics that provide a very immersive experience, however a unique display also requires unique content development techniques. This three hour workshop will provide in-depth guidance on the actual process of developing content for dome displays. Content types include 360° panoramas, 360° videos, and virtual environments. The HIVE and Pawsey have a range of content capture equipment available to allow you to capture compelling dome content. Dome displays are also becoming more widely available. The workshop will provide specific step-by-step guidance on how you can turn your imagination into a dome experience. In the afternoon we will also offer an optional opportunity to capture some content suitable for displaying on dome displays, and time for extended Q&A on dome content capture, and perhaps discussion of content production ideas.
In order to reduce repetition of content we ask that everyone attending this workshop has either attended the earlier one hour seminar (“Content Creation for Dome Displays”) or watched the video recording of the talk. This video will be made available on request.
