Digital City System

This digital city system is the final project of my HCI course, it is intended to cater to today's customers growing needs of "immersive experience".
Therefore, I realized a digital city, in which users can roam around freely and enter the buildings to view the internal design and decoration.
I tried to bake the internal light to make the indoor scene fancy, and use a procedural skybox to simulate the day-and-night alternation in different 4 seasons, so as to simulate a genuine environment in a city.
From my perspective, this project will be much more usable if developed on AR or VR platform. I will try developing a VR version if I had a chance.
