Motivation

Visual Computing helps for many applications(visual solutions for data intensive problems)

research often solves problems suspected by researchers

the VRVis Research Center solves real problems (in cooperation with companies = from the real world!)(in cooperation with companies = from the real world!)

this leads to practically useable results and publications

for this VRVis researchers need to havenumerous „non‐academic qualifications“

Computer Graphicsgraphical user interfaces, animations ...

Computer Vision / Pattern Recognitionmodeling of human vision…

Visualizationrendering of volume data + higher dim. data…

Interactive Visual Analytics visual analysis of multi dim and abstract data

Visual Computing includes:

visual analysis of multi‐dim. and abstract data…

Optical Sensorsrecording methods for visual information…

Modelingdigital models of data and images…

Rendering real‐time visualization, lighting simulation, hidden parts…

Virtual / Augmented Realitycombination of real and virtual objects…

Requirements on the Staff

diff i h i li i i d i i iHow different is research in application oriented institutionsfrom research at universities?

communication with real users

(in addition to 1a project fulfillment!)

Requirements on Staff


use of real data


Requirements on Staff Use of Real Data

cracks

and:exceptions!exceptions!exceptions!

cracks

missingdata

errors, e.g. wrong normals

Use of Real Data

and most of all:huge data sets(too large for commercial products!)
