My kind of desk – pre-work within Research IT office, for a touchtable and projection display stand at the University of Manchester Regius Professorship award celebration.
Using the new Acer Predator (17 G9-792) laptop, with an inbuilt great graphics card (NVIDIA® GeForce® GTX 970M with 6GB GDDR5 Dedicated Memory), and touchscreen – bits borrowed from UoM and STFC visualisation groups along with (STFC www.CCPi.ac.uk) tomography data and the drishti-prayog volume visualisation software all appear to run extremely sweet.
Moving this to the exhibition area within the NGI (National Graphine Institute) with a HDMI splitter should then be suitable for 100’s of viewers per hour …
Show setup for 150+ special visitors. This example on the screen (one of about 15), just prepared, showed work from by the new EPSRC Flagship CCPi fellowship, Daniil Kazantsev et al from RAL that using multiple volume vis transfer functions highlighted the centre and the fractal edge of slices showing dendritic behaviour (even measurable).
The laptop and small workstation were hidden and all you see is the touchtable, controlled by the operator or user on the right, and the main screen allowing multiple people to view and comment at once.
The volume visualisation was a little tricky as the raw data had been pre-segmented already so I had to create a boundary edge by interpolation and reducing the size of the complete object.
There was a talk by Regius Phil Withers after a presentation of the award from the Queen’s representative, as well as a question and answer session chaired by the President of the University of Manchester.
Not really vis but this was important in the day.
Back in the Computer Lab., at the University of Cambridge in about 1992 there were at least two filter coffee systems; both running on a slow drip-filter setup. The Rainbow Group had access to one machine in a walk down a corridor to a small kitchenette; but the network team had to travel a lot longer way to their coffee machine. A problem of lack of enthusiasm to travel meant that often they would find an empty coffee pot – or even worse stale coffee. A solution was a camera video stream that linked to the linux server and stream images to X Windows. So when new fresh coffee arrived this would be obvious from the image on everyone’s desktop.
http://64bits.co.uk/ have been rebuilding old systems and in East London they rebuild the Cambridge Coffee pot scenario – with similar equipment. There is a wikipedia page on the original: https://en.wikipedia.org/wiki/Talk%3ATrojan_Room_coffee_pot
Is video streaming – visualisation – well definitely yes as it is an interpretation. Due to low quality network speed and CPUs; the small 128×128 video stream of images had to just include the coffee level and also the fps was about one frame every few seconds – but that is a good rate and good enough resolution for “coffee pot observation”.
Touchscreens are all the fashion – but any system you deploy is expected to work smoothly and intuitively – including visualisation ones. There are some company purpose-built systems for exhibitions that are far from cheap although they may work well they can also suffer from lack of agility when recreate new content. There are also simple tablet/phone software options available for touching and manipulating volumes but can have limited graphics ability.
Over the last couple of years we have collaborated informally with partners to share knowledge on open source solutions for large scale volume visualisation (say greater than 256 x 256 x 256) on a touchscreen device.
A hardware specification service has evolved where we can assist with advice and quotes for touchscreen and workstation visualisation nodes, as well as more importantly related software installation; used for exhibitions and PE. A wiki is available at:

At Manchester, connecting through Research IT, there are now groups available to informally share equipment and expertise – and as importantly share experience in interacting with the public and other scientists – even if their research data content is often diversely different.
Both being asked to be available for the upcoming Presidents Office organised ‘University Celebrations of Regius Professorship’ on 25 April 2017 in the NGI.
I was having to wait for a train at Euston Station in London- and visited the Welcome Trust that is opposite, and they had an exhibition on the story of electricity.
One neat bit of 3D visualisation was near the end of the exhibition and showed a 1950s Electrical Consumption Graph:
“This 3D graph, compiled by the planners of the Central Electricity Generating Board, represents the daily electrical energy consumed over a period of two years during the 1950s.”
Unfortunately, not very interactive – with the glass protection, although you can view it easily from many angles; but a few things were right in that they chose two years of data. This is a trick used today even when there is only one year’s data available – where you recommend copying the data – and was used by Florence Nightingale in her more radical circular statistical plots (of morbidity rates during the Crimean war). The problem comes with matching the ends up – between January with December in most calendar statistics. These should be continuous, but the human eye has difficulty in spotting smoothness etc. If you can not use circular plots and in this case with card indexes this would have been very difficult, then by repeating the data or here using two years of data, you can see the changes between December and January as clearly as any other pair of neighbouring months.
In principle the whole medical topic of radiotherapy analysis is full of visualisation. A recent sandpit discussed Monte Carlo techniques that are critical within the radiotherapy planning / beamline construction / or just radiation safety / etc…
So where is the visualisation interests as the main need is to make these processes faster and more useful. We did pitch three small projects to look at:
More details to come. This was organised by the Advanced Radiotherapy network https://www.advanced-radiotherapy.ac.uk/ and thank them for allowing these ideas to be pitched.
There were global other issues and “Focus Where it Matters”, was a industry quote and will reuse here; so they need not just to increase speed but also to control inaccuracy and inconsistency.
