Motivation Letter The purpose of this motivation letter is that apply for Tomsk State University master's program, Information Technologies in Science and Instrument Engineering. Last July, I graduated from the East China University of Technology(ECUT) in Software Engineering. During my studies, I attended activities of coding very positive and did two internships. I participated in the China Software Cup competition when I was a semester, and I led the team. The remaining two players are my classmates. The name of the project is the 3D model browsing and interaction system. We started our journey with passion. With the help of the Internet and the library, it took one year to complete this project, with the function of importing 3D models, rotating and zooming in and out. This project won the second prize in the school fund project and received some bonuses. From this project, I came into contact with computer graphics, was deeply attracted to it, and decided to work in this field. After completing the courses and tasks arranged by the school, I used some spare time to learn some basics of graphics and participated in the official document Chinese Translation Team of Blender, which translated English documents into Chinese documents for the reference of developers. In February 2018, my two teammates and I participated in the Interdisciplinary Contest in Modeling (ICM) competition. I was mainly responsible for the programming part, using Matlab to process the data, analyze and verify the model. Through the efforts of the team, we won the Honorable prize. In April 2018, I started a three-month internship. During this period, I participated in the company project "Cross-border Travel". I was mainly responsible for the automatic control of the camera, realized face recognition, portrait counting and other functions through the interface—the project exhibited at the World VR Exhibition in October 2018. In April 2019, I joined another company engaged in mobile phone game development, mainly developing mobile games with Lua and C programming language. I thought that when I contacted the game industry, I was able to study computer graphics and computer vision more deeply. But the development work in the company is generally pipelined. I'm the kind of person who likes to solve challenging problems. Then I decided to continue to study for a graduate degree.
