I don't know, it is like graphic design. Although I am a kind of guy, I didn't touch where I didn't touch it. When I was high in high school, I like three-dimensional geometry, and later, I got a mathematical analysis class in college. I preferred graphics, and there is always a three-dimensional view of a stereoscopic pattern in my brain. I always think why these things have that great attraction to me. Yesterday, I was shocked by the computer system, but unfortunately touched my class. Today, I asked the teacher to ask the teacher, splashing cold water (because he didn't know my attitude), saying that they learned very fur, not used, and difficult to learn, self-study is more difficult. Although it is a thing that can be studied in a lifetime, but in the end, I feel awkward. When I saw a little light, I found that the light was really weak. I like it, I don't know, but who can tell me how to go this road?
