using 3D and visualising 3D

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. scientific visualisation (I) • 3D graphs for non 3D data • 3D histograms etc. • hard to see 3D for static pictures • use colour as redundant cue • use movement • allow user controlled rotation etc.

5. scientific visualisation (II)real 3 D data • scalar data • temperature, density, pressure • vector data • wind flows, electromagnetic fields

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

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

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

13. Hierarchical data

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