Interactive 3D visualization

• Consist of computer generated 3D graphical presentation and interaction methods for moving around in a virtual environment and manipulating it.

• Construction perspective: give the user a better understanding of a building to be built, to select among design choices, to represent simulation results in a comprehensible way´.

Product model visualisation

• Visualising construction industry product model data can involve:• various domains: architectural, structural

engineering etc.• Simulating different properties: thermal,

lighting, acoustical and visualizing the results

Current situation in interactive 3D in construction

• Nice looking visuals for marketing and lighting simulation.

• Other characteristics of a building is visualised for other technical persons: like thermal comfort data.

Building quality from the end-user perspective?

• Quality of living is a strengthening trend.

• How about visualising the quality of a building solution beforehand to the end user of the building?

• Factors of interest like: thermal comfort, ergonomics, lighting quality, space information

• We need illustrative enough means to present the relevant product model and/or simulation data to a non-technical person.

• Examples: thermal vis, spatial ergonomics

Research question

• What visualisation methods could be used to enhance construction product understanding even for non-technical persons?

Interaction theory

• Human computer interaction in graphics applications can be thought to be composed of basic interaction tasks:

• Object manipulation (indicating an object, selecting, moving and orienting, releasing)

• Alphanumeric input• Navigation in a 3D world

• Usability viewpoint: these have to be tackled first!

Navigation = locomotion & wayfinding

• Locomotion in 3D worlds:• how to move ones’ viewpoint• interaction: input device -> interaction

technique in software -> visual feedback of motion to the user

• different input and display methods: mouse, keyboard, joystick, data glove, spacemouse & different displays

Navigation = locomotion & way finding

• Way finding• Mental process of knowing where things

are in a 3D world and knowing how to get there.

• In the real world we use cues to remember places: turn left after the green house.

• We also use maps.

An example from the construction world

• Zermatt, a software for viewing ArchiCAD eported architectural models.

• The building model and the viewing software form a single .exe file that can be easily distributed.

Zermatt

• Navigation:• Movement is first person –type, i.e. looking through a persons’

eyes. • Keyboard for movement, collision constraints mimic real world

type movement in a building.• A map to aid comprehension of the building structure.

• Observations:• first person view, with constrained ”walking” gives some sense

of being inside of a building.• it is not easy to form an opinion of the building as a whole or of

a floor plan of a particular storey.• NOT MUCH USE OF DOMAIN SPECIFIC KNOWLEGDE

Current status: New navigation technique in development

• Combines ideas from games for first person/third person views.

• Takes advantage of IFC model structural information:

• multi-scale navigation by recognising where the user is located: building storey, space

• Software prototype implementation is under progress.

• Let’s see what happens next.
