Virual Oral Question and Answer


IEEE/ICACT20210167 Question.8 Questioner: seunghee5@etri.re.kr 2021-02-09 오전 10:12:30	IEEE/ICACT20210167 Answer.8 Answer by Auhor mots@etri.re.kr 2021-02-09 오전 10:12:30
Digital twin seems to be an attractive topic. What are the main differences between digital twins and existing BIM and Vitual City? Also What are the main advantages of Digital Twin?	That's a great question. Virtual city and BIM technologies have similarities in terms of information models in the ditital space, but they are data model constituting a smart city and a visualization tool in the field of computer graphics. Digital twin is different from BIM and virtual city in that it has simulation platform and has interoperability between physical and digital models. Thank you.
