About me

Hi! I am currently a master student (PhD-track) in computer science at UBC, working under the supervision of Alla Sheffer. I am excited to explore research topics in **computer graphics and geometry.

I graduated from the Tang Ao-Qing Honors Program at Jilin University, where I had the opportunity to explore various research areas, including computer graphics, computer vision, and data mining, through internships at Zhejiang University and the University of Alberta.

Projects

1. CUDA-Accelerated Rasterization and Ray-Tracing from Scratch
   Finished during my internship the University of Alberta [Project Link.]
   
   The renderer features two pipelines: one based on rasterization and the other on ray tracing. It also includes optimizations such as ambient occlusion mapping and shadow mapping. I also achieved over 100x rendering speedup through parallel computation using CUDA on ray tracing pipeline. Writing codes to translate elegant mathematical concepts to visually appealing images always excites me.
