Google Model Viewer

Powering 3D Display and authoring on Web

Model Viewer is an Open Sourced library to power interactive 3D display on the Web.

My main contribution for the project is the authoring workflow for model viewer, where user can interactively import, modify and preview models. The tool would also generate fully functional model-viewer snippet for exporting.

This was used to power 3D display ads from Google.

Contour Crafting Planning

Visualization and Design Automation for 3D printing.

Contour Crafting is a layered fabrication technology developed by Dr. Behrokh Khoshnevis of the University of Southern California. Contour Crafting technology has great potential for automating the construction of whole structures as well as sub-components.

I joined the Contour Crafting team on August 2017 and am currently working on visualization of printing process and automation of facility placement on software side.

I designed and implemented Unity framework to visualize printing process of building construction, enabled architects to control printing parameters real time.

I introduced the team with cloud platform provided by Autodesk, reduced the data translation time by 80%.

Quantum Escrow

Cloud Platform for Building Information Modeling

Quantum is designed to be the next generation of cloud platform for the building information modeling (BIM) industry. It allows architects and developers to collaborate on the same project with minimized data transmission. Additional Information here.

During my three months of internship at Autodesk, I collaborated with a team with four full time developers to research and develop the central data pipeline of Quantum. My specific responsibility includes building Node.js API server, prototyping front-end web application in 3D and testing applications.

By the end of my internship, the team was able to transimit data with twice the efficiency as before, with also 80% less memory taken on the front end. I contributed 15000+ lines of code on both front-end and back-end with 80+ commits, more than 35% of the codebase.

Cortex

Machine Learning for Business Intelligence.

Cortex is my Capstone (Senior Design) project at University of Southern California. We are collaborating with a start up company in Santa Monica to apply machine learning on business intelligence, predicting the best time and content to post on social media.

I am working with a team of four USC students to extract the data from Facebook, Twitter and Google Analytics, prepare data in RDS, training datasets and deploy training results on AWS. My personal responsibility includes visualize data, prepare data fields and deploy application.

Within a month of development, we have processed the dataset, trained data to predict engagements with 70+% accuracy, and deploy first version on AWS.

Doodle Noodle

Virtual Reality game with body control

Inspired by Leap Motion's Pinch Draw module, Doodle Noodle is a intuitive Virtual Reality game that allows user to actively engage in the gaming space with no controller.

Players use a "pinch and drag" motion to create 3d pathways in mid-air, from point A to G. Bob, the pony will follow along the path and if she hits the moving cube. The game would respond with player's gesture, no controller and keyboard are ever needed to play the game.

During the 36 hours hackathon, we finished the UI/UX design, animation, game logics and integration. My specific responsibility includes game logics and integration on Oculus and Leap Motion SDK.
