Digital Vancouver (Project for GeoSim)

 

Unity3d generalist programmer      August, 2014

 

The goal of this project is to explore the possible usage of a accurately simulated virtual 3d city. The client of this project is GeoSim.

 

My Roles

Unity3d programmer: Collaborate with other programmers to import all the 3d models into unity. Build basic interaction and animation for the application.

 

What I did

-Implemented different animations for different characters.

 

-Brain storming together with professors from NYU and MIT to figure out the different ways of using the 3D city.

 

Challenges

Because we have 4 blocks of high detailed models of downtown Vancouver. They all have high-res textures and the polygon number of the model is also very high. The optimization for its performance in unity is a big challenge. To solve that problem, we could use occlusion culling and dynamically load all the art assets to release the pressure of the cpu and memory. Also for the rendering part we could use light mapping to simulate the realistic lighting effects.
