In this paper, we propose an interactive system that can quickly convert a 2D cartoon painting into a 3D textured cartoon model, enabling non-professional adults and children to easily create personalized 3D contents. Our system exploits a new approach based on solving Poisson equations to generate 3D models, which is free from the limitations of spherical topology in prior works. We also propose a novel method to generate whole textures for both sides of the models to deliver colorful appearances, making it possible to obtain stylized models rendered with cartoon textures. The results have shown that our method can greatly simplify the modeling process comparing with both traditional modeling softwares and prior sketch-based systems.

Real-time Object Tracking And Pose Estimation On Mobile Phones
Lele Feng, Xubo Yang
Shanghai Jiaotong University 2014 Outstanding Bachelor Paper

In this paper, we analyze the existing object recognition and tracking technology based on natural features, and implement a real-time object tracking system on mobile phones for some AR applications. The original SIFT is known to be a strong, but computationally expensive feature descriptor. FAST corner detection is fast, but the generated information of key points is poor. We achieved the object recognition on mobile phones through a modified version of the SIFT algorithm using FAST. And pose estimation can be obtained from the transformation matrix matching between the identified targets and frame, and then display three-dimensional objects in the screen. In addition, we implemented a PC client management tool for management of all preprocessed target pictures. We give detail descriptors on how we modified the algorithm to make it suitable for mobile phones. We present evaluations on robustness and performance of the system, and implement a demo application in real world. Finally, we discuss the direction of future works.

Happy Tree

Development Tools: Unity3D, Shader, C#

A personal independent game. The player needs to help the Happy Tree blooming. Flowers can be composed of six kinds of elements. Each element has two attributes, speed (moving speed) and strength (growth rate). The player needs to make his own elements occupying all regions in order to win.

Real-time Stereo Rendering System For Naked Eyes

Development Tools: Unity3D, Shader, Compute Shader, C#

This project intends to produce real-time stereo effects for nake eyes by using RGB and depth textures as input. By exploiting GPGPU, I increased the efficiency of the algorithm by 130% and finally achieved real-time rates. The system supports 4k resolution and Windows platform.

NPR Lab

Development Tools: Unity3D, Shader, C#

This project is intended to realize some NPR effecs by using Unity3D. These effects include tone-based shading, stylized highlights for cartoon rendering，real-time hatching, real-time pencil rendering and so on. This project is still under development.

Pencil Drawing Production

Development Tools: Matlab

This project implements the algorithm proposed by Lu C et al. in their paper Combining sketch and tone for pencil drawing production.

Virtual Fitting Room

Development Tools: Unity3D, Json, C#, Apache Tomcat，MySQL

The course project for Advanced Introduction to Software Engineering. Virtual Fitting Room is an online system for consumers to find suitable clothes effectively. The system supports sign up and login, and the user can customize his/her virtual model by adjusting height, size, complexion and so on. The system also supports filtering based on brands, types and other conditions. If the user is attracted by some cloth, the system can direct to the shopping web page. In this project, I was responsible for the client-side realizations, including writing requirements, designing interfaces, coding and communicating with the server-side.

Ninja Fighters (Formerly known as Ninja World)

Development Tools: Unity3D, C#

Ninja Fighters is a 3D mobile game lauched by Mobage. The game inherits the story of the popular Japanese anime Naruto, and integrates a lot of modern gameplay in the meanwhile. I participated in the development of the game as an intern in DeNA China in 2013. I developed several important modules under the coorperation with my colleagues.

Let's Fly

Development Tools: Unity3D, C#

Let's Fly is a flight shooting game on Android platform. This project obtained the third prize in the Forth Android Application Development College Challenge Competition in 2013 and was one of top ten applications in the software exhibition of Software Engineering in Shanghai Jiao Tong University in 2013.
