What is Visualization
•
As described on Wikipedia•
Illustration
•
Information Graphics –
visual representations of information data or knowledge
•
Mental Image –
imagination
•
Spatial Visualization –
ability to mentally manipulate 2dimensional and 3dimensional figures
•
Computer Graphics
•
Interactive Imaging
•
Music visual
IEEE on Visualization“Traditionally the tool of the statistician and engineer,
information visualization has increasingly become a powerful new medium for artists and designers as well. Owing in part to the mainstreaming of computer graphics and the democratization of information sources on the Internet, this new cadre of creative researchers has discovered the possibility of visualization techniques to reveal thought-provoking but otherwise hidden narratives. Often using little more than home computers and widely available programming toolkits, artists and designers have taken material evidence into their own hands and expanded the conceptual horizons of information visualization as a mode of artistic practice and critical inquiry.”

TRB on Visualization“…visualization technologies have continued to evolve at a considerable pace,
yet the highway transportation industry is still years behind its counterparts in aerospace, architecture, plant facilities, automotive, shipping, and others, when it comes to fully embracing visualization tools and the corresponding mindsets.
Times, however, are changing. Recent technologies are gaining the awareness and interest of transportation organizations.
As fascinating as these advancements are, it is still not clear how visualization directly assists in addressing our transportation needs.”

A Visual of Visualizationhttp://www.visual-literacy.org/periodic_table/periodic_table.html
Basic Visual Goals
•
Able to reach 8th
grade level
•
Attention grabbing
•
Doesn’t require explanation
•
Says everything without saying anything (hidden narratives)
•
Ability to create either stationary, animated or interactive images –
driven by the viewer experience
Image Rendering (Ray Tracing)
•
Rendering is the process of creating an image by calculating expected behavior of light against a given material and surface type
•
Referred to as Ray Tracing since light rays are diffused and/or absorbed during the process
The Graphics Turing Test
•
Based upon Alan Turing’s 1950 test of Artificial Intelligence which states “a judge in three way conversation between a computer and another human should not be able to distinguish the computer from the human”
•
Graphics variant sets bar at real time rendering for truly photo realistic animations as the scene is modified by human interaction –
virtual reality or
“The Matrix”
effect
•
Not there yet, but VERY rapidly approaching – ABC News article dated 4/4/08
The Hardware Research
•
Scalable Visualization using off the shelf components and Monte Carlo estimation http://www.hp.com/techservers/hpccn/sci_vis/scale_vis_otsc.html
•
High Performance Clustering for Visualization

Where do we start
•
Narrow the opportunities to small set of immediate realistic goals for visualization followed by phased approach to a series of more complex goals
•
Decide what the unspoken narrative should be
•
Draw Roadmap for achieving desired result•
Tools necessary for solution will be determined as a result of roadmap planning
•
Staff resources & skill set
What if we wait or do nothing
•
Risk of being viewed as stagnant in our presentation mediums
•
Risk of another party visualizing a narrative differing from our own and gaining credibility especially given the emergence of many good free tools
•
Likelihood that younger generations will not engage in the process as they are completely accustomed to visual information dissemination
Flash Web content, iPod, YouTube, MySpace, Facebook, Multi-faceted Gaming ConsolesSometimes referred to as snippet kiddies by media designers
Possible Uses
•
Land Use Image Rendering•
Microsimulation model presentation
•
Interactive Public Involvement Utility using Blender Game Logic function•
Excellent example in Carnegie Mellon University's Alice project. Teachs kids Java programming language while they play a SIMS like game.

•
Video –
traditional or rendered•
Distribute via YouTube, Myspace, Facebook
•
Enable content available via cell phone
Possible Uses
•
Google Earth –
use photography placeholders to show current condition along with rendered “after”
image
•
LCI and DRI evaluation by rendered concept submission
•
Application showing effect via rendered images when capacity and transportation mix changes (buildings disappear for right of way change, transit additions, actual lane widths)
