  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
