Visualizing Glacier Ice Flow in an Immersive Environment
Pekka Ekman · 2000
This report describes the application of immersive visualization techniques to the problem of visualizing glacier ice flow. An application based on IRIS Performer, pfCAVE and VTK was developed to implement the visualization. A high degree of interactivity is maintained in the application through the use of movable probes controlled by a positional tracker. VTK proves to be a very powerful visualization tool but one that has to be used with care in order to achieve good performance. A major problem with the development of visualization applications for immersive environments is the lack of a general graphical user interface system designed for these environments. Visualisering av isfloden i glaciarer i en immersiv miljo Denna rapport beskriver hur isfloden i glaciarer kan visualiseras i en immersiv miljo. En applikation, baserad pa IRIS Performer, pfCAVE och VTK, som implementerar visualiseringen har utvecklats. God interaktivitet uppnas genom anvandandet av positionssensorer kopplade till verktyg i applikationen. VTK visar sig vara ett kraftfullt visualiseringsverktyg som dock maste anvandas med viss forsiktighet om god prestanda skall kunna uppnas. Bristen pa generella grafiska anvandargranssnitt for immersiva miljoer ar det problem som utgor det storsta hindret vid utveckling av immersiva applikationer.
