Ok, this week we deal with the translation and rotation of objects. The basic translation and rotation is not very hard. But I tried to write my own utility class, intending to complete the homework by using the syntax like myquad.translate(). I found it is not a easy job. Because in OpenGL the translation is like the reverse of the real world translation. In OpenGL, I have to moveĀ  the matrix which is a frame of reference as well I think first. And then, draw the object. However, in my utility class I want to draw the object first and use different functions to manipulate it. I can’t figure it out this week. But I will keep thinking about it.

Here is the files including the unfinished utility class.
