Workshop: Computational Tools and Technologies for Construction Practitioners
February 13, 2008
Shafee Ahamed and Niall Murray
Advanced Visualization Technologies and
Topics for Discussion
• Visualization Technologies and VR Techniques
Technologies and
Techniques
• Existing Technologies • Issues • T he FutureVirtual Environments
• These are technologies that allow you to create objects in a virtual environment that exists only inside a computer
• The environment can range in complexity from a virtual house, to a virtual city, to a virtual
construction process
• The “objects” can be stationary or dynamic
• Individual immersion is accomplished by allowing the observer to interact with virtual objects

Applications of VR in
Construction
• Why virtual reality ?
• Where can it be used ?
• How NRC and others are using this technology.
Immersive Visualization Original CAD model
Why Virtual Reality in
Construction
• Modeling and simulation of construction processes • 3D presentation technology
Many technologies exist to do the job, but we would like to be:
Faster, Cheaper, Better, Super …
Maximize the Information and Minimize the Cost Before building it physically, tell them ... show them
Looks real Sounds real Feels real
Where Virtual Reality is
used in Construction
• Space Modeler Landscaping Interior Design • Concept Design• Design of sub-systems, HVAC, MEP • Ergonomic Analysis
• Fire Risk Assessment • Urban Planning
• Evaluation of Construction scenarios • Simulation of Construction processes • Virtual Testing
Where Virtual Reality is
used in Construction
How Virtual Reality is
used in Construction
Objective: To identify the concerns about the impact new arena complex will have on the proposed
location in city of London
Data:
• Plan view map of the city • 3D view of the city
• 3D model of the proposed arena complex • How much and how far
• L.O.D and how realistic • Terrain details
Information:
• Modeling, transformation, translations & scaling
• Image resolutions, distortions, scene clutters, etc
Modeling & Imaging
• Cleanup, Transformations to VR world • Integrating, programming and control
