I gave this talk at the ITEA3 Smart City Business Event. In this talk, I introduced mago3D project, an open source based digital twin platform first. And then shared the real cases that I and my company have carried out in various industries. I concluded the talk with what I've learnt from these real projects. Some food for thoughts around digital twin were provided for further discussion.

24. A City is NOT a Computer
<Source: https://www.ordnancesurvey.co.uk/business-government/innovation/happens/articles-ehs/smart-cities-digital-technologies>
“Despite the futuristic images the term conjures, a “smart city”
is merely a well-managed city aided by digital technologies.
One of the primary challenges in achieving success for smart
cities, and the reason many initiatives have failed to make it
past the pilot stage, is that they have been driven by a focus
on implementing the technology rather than achieving the
end policy goal, such as improving access to education, or
better transport links.”

27. STANDARDS?
• Standards are not widely accepted across industries.
“Why should we export our Revit file to IFC?”
“We convert our 3D data to CityGML only because government order to do that.”
• Sometimes data converting lose some part of original information.
• Clients prefer to provide original native format.
• Converting format gives another hassles.
29. WebGL vs Game Engine
