using 3Dand visualising 3D

“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

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.

scientific visualisation (II)real 3 D data

• scalar data– temperature, density, pressure

• vector data– wind flows, electromagnetic fields

seeing inside?

• Problem - we only see the surface

• Solution - reduce ‘density’ of data– points OK (stars) - show samples only– translucence– slices– lines

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

information visualisation

• abstract data

• use 3D to increase virtual space

• humans understand physical world

Hierarchical data

Temporal fusion

• moving changing images

• successive images

• parallel changes
