Editor's Notes
- Det er her vi starter. Der ute er den virkelige verden, og det er den vi skal gjenskape på egnet måte på skjermene våre. Virkeligheten kan for eksempel se slik ut. En veg med fotgjengerovergang og en rundkjøring, gang- og sykkelveg, en støyskjerm, noen flaggstenger, et politihus og en halvferdig fotballstadion. Dette kan vi gjenskape som et kart, der de ulike objektene vi ser på bildet er vist med symboler og farger. Men for at dette skal kunne fungere må applikasjonen vår forstå hva det er vi har lagd modeller av og vil gjenskape, og hvordan vi har kategorisert for eksempel vegkategorier. I en annen sammenheng, og stadig oftere, kan det være behov for å gjenskape virkeligheten i 3D, og det gir som kjent enda noen utfordringer.
