The Last Signal

Category: Building Virtual World
Platform: Kinect
Development Time: 1 month
Team Members:
          Producer/2D Artist - Brian Lee                 Level/UI Designer - Scott Chen
          Programmer - Ruijie Liu                         Sound Designer - Shibli Mansuri

A Kinect platform game that tells a story of the journey of a waveform. The player controls the amplitude and frequency of the waveform using both arms, and must guide it to a broadcast tower in order to send his signal to the entire world. This game was later polished and purchased by Microsoft as a prototype of a Kinect Fun Labs gadget.

3D Stereoscopic Video Player

Category: Undergraduate Academic Project
Platform: NVIDIA 3D Vision active shutter glasses and display
Development Time: 3 months

During my junior year, I implemented a 3D video player that works with NVIDIA 3D Vision shutter glasses. Basically, this project is about passing the stereo image pair to the frame buffer in the correct format that the graphics driver can recognize. It is implemented through the VMR9 filter of DirectShow.

       

 

Graphics Card Hardmod

Category: Individual Project

I was keen on optimizing the performance of my PC in order to play graphics intensive games. To overclock the GPU to a higher frequency, I modified the feedback resistance of the core PWM circuit. In this way, the voltage of GPU was increased so that the GPU frequency can be overclocked from 540MHz to 750MHz. The result showed my Geforce 8600GT got about 40% higher benchmark in 3DMark06 compared with the referenced board.

                                                    

  

Install Mac OS X on PC

Category: Individual Project

There was a time when I loved the UI of Mac very much but cannot afford one. Motivated, I read many tutorials on how to install Mac OS on a PC. There were many times when I failed, analyzed the problem, found the solution and tried again. During this process, I learned a lot about partitioning, boot loader, hardware drivers and the architecture of Mac OS. To my delight, my hackintosh can run without crash in the end.
