PROJECT EXPERIENCE

Memory Cage
Team member of 3, Designer, Programmer

• Designed and created a Rouge-like RPG game, in which players need to beat different kinds of enemies to enhance the role level and capability. It consists of turn-based strategy and real-time combat models. The terrain varies in different play rounds.
• Applied A* path finding algorithm and A* finite state machine to arrange enemy walking routes, including standing still, searching for the player or friends.
• Using shader to render the game surroundings black, with bright effects only occurring around the character. It greatly increased the feeling of adventure for players.

Billboard (An OpenGL-Oriented Game)
Designer, Programmer

• Designed a planet-like pool table, with the terrain generated by 2D perlin noise and texture generated by 3D perlin noise.
• Using VBO index buffer to speed up the efficiency of model loading and rendering based on GPU.
• Applied particle system as the ball trail, and design the shading of the particles color.
• Implemented a 3D collision system to control the moving trail of the ball on an irregular field.

Exokernel Design and Implementation
Designer, Programmer

• To understand the boot loader mechanism and realize formatted printing to the console and the stack tree, for the use of debugging.
• Implemented memory management for the kernel, using page list and page directory in physical page management. Reflected it to virtually memory and allocated address space for kernel.
• Made a single user environment for the program to run and handle system calls and exceptions like page faults and breakpoints.
• Completed a preemptive multitasking environment and some support for multiprocessor, including lock, round-robin scheduling and copy-on-write fork. Interrupt request (IRQ), inter-process communication (IPC) and a simple file system were also created.

Photo-Note (Android App)
Team member 4, Designer & Developer

• Designed and developed a new tool that could accurately read and extract the same text content from paper materials to TXT document in the cell phone. Greatly enhanced users' recording efficiency, enriched users' storage mode and information sharing methods.
• Divided the development cycle into preprocessing, layout analysis, character recognition and layout recovering. Applied Optical Character Recognition (OCR) method in character recognition process.
• Reached a good accuracy of 90% character recognition by discoloration, binarization, denoising and OCR. Successfully transferred recognized text into cell phone notes, with more functions including, text editing and searching and synchronization in cloud server.

Basic Database Function Implementation
Designer, Programmer

• Applied Hashing and caching mechanism to construct the core database operations of Create, Read, Update and Delete. Stored the data in hard disk in the form of offsets.
• Used index to fast locate file position in the datasets based on hash table and open chaining structure.
• Cache was used to store part of the data to be written in the file, conveniently for insert and update operations without modifying file contents each time. Data get written in cache first and then files.
• Tested to get an operation time-consuming rank from long to short: search, insert, update and delete.

Hello Corn
Designer, Programmer

• A linking-like game implemented with HGE engine. Player should link as much as possible corns to get higher score.
• Independently drew the character of the corns and designed multiple special corns with different functions, including line eliminating and row eliminating.
• Designed different stages and player should achieve different goals to unlock them step by step.

LEADERSHIP & ACTIVITIES

Alumni Association, SJTU
Core member

• Responsible for visiting center daily management, including personnel scheduling and training.
• Planned the alumni couple homecoming activity in the 120 anniversary of SJTU.

WORK SAMPLE

Linking Game

In 'Hello Corn', player should link as much corn as possible to get higher score.

The picture shows the charactor I devised to replace the original corn image:
• Different kinds of eye patterns represent which determine whether to eliminate in row, in column or the eight corn images around.
• Different colors manifest different kinds of corns. You can only link the corns with the same color.
• The light warpping around the corn indicates it has been linked.
• The tied foot means the corn is frozen which cannot fall down when the corn below is eliminated.

Memory Cage

At first, my friend wanted to design only a rougelike RGP game. But I am very intrested in the SLG game just like the famous SLG game Fire Emblem designed by Nintendo. So at last we designed a game like this, a RPG-SLG mixed rougelike game.
My contributions to the game:
• Discussing with my friends about the designing.
• Designing the dialogue and world view in the game.
• Most taking part in the SLG part, including complete a A* alogrithm and Finite-state machine.
• Also doing some help in the animation progress and render progress.
