Enhancing Data Visualization in 3D: Graphics and Interaction Techniques

Utilize 3D visuals to emphasize sculptural window elements, implement drop shadows for figure-ground separation, and improve affordances. Explore mapping data to real-world 3D features, and enhance scalar and vector data visualization. Overcome challenges of static 3D images through interaction and movement, enabling users to see inside objects. Incorporate virtual components like bubbles and smoke for enhanced information visualization. Aid comprehension of hierarchical and temporal data fusion through dynamic visual techniques.

Presentation Transcript

  1. using 3Dand visualising 3D

  2. “sculptural” window elements • highlighting • drop shadows • may help distinguish features– figure ground separation – e.g. X Motif – everything in sculpture! • improve affordances– buttons are for pushing

  3. 3D data visualisation • arbitrary parametrisation • e.g. height  weight  lifespan • build on 2D features • e.g. country  car production • N.B. volume or height! • map to real 3D world features • e.g. virtual wind tunnel

  4. 3D graphs for non 3D data • 3D histograms etc. • may be misleading (3Dpie charts!) • hard to see 3D for static pictures • use colour as redundant cue • use movement • allow user controlled rotation etc.

  5. real 3 D data • scalar data • temperature, density, pressure • vector data • wind flows, electromagnetic fields

  6. seeing inside? • Problem - we only see the surface • Solution - reduce ‘density’ of data • points OK (stars) - show samples only • translucence • slices • lines

  7. seeing inside - use interaction! • move in the environment • look around the back! • manipulate things • pick up, open up • control cuts, density etc. • e.g. virtual human • insert markers • virtual bubbles, smoke

  8. information visualisation • abstract data • use 3D to increase virtual space • humans understand physical world

  9. Hierarchical data

  10. Temporal fusion • moving changing images • successive images • parallel changes
