1.Every matrix M is associated with a coordinate system. This coordinate system has origin (t0, t1, t2) and vectors (a00,a110,a20), (a01,a11,a21), and (a02,a12,a22) as axes. Matrix M maps the standard coordinate system to the coordinate system with the origin (0, 0, 0) and axes (1, 0, 0), (0, 1, 0). 阅读全文
