" History , technical specs , overviews of VJ gear , interviews - wow , The VJ Book will become the bible for video artists for years to come . Paul Spinrad even dives head - first into the copyright concerns that VJs have to cope with as both aggregators and producers . It ' s a great handbook for VJs , experimental film - makers , or anyone else who ' s interested in interactive media control . And after reading all the interviews , one thing is clear : there is no one way to approach the art of VJing . " - Grant Davis ( V J Culture )

" Recommended reading for anyone who ' s interested in the ongoing evolution of human expression , as we continue our dialogue with technology . Gives a sense of the real human personalities that drive a technologically - mediated art form . " - David Last , musician , VI , and co - curator of " Synaesthesiologists " for the 2 0 0 4 New York Video Festival

3D软件里面的四元数旋转WXYZ

在四维空间里面，会有很多不可思议的东西，比如，四维空间里面存在两个圆，它们互相垂直但是又没有交点（想不到吧？）。因此，四维空间里面对原向量先左乘一个四元数，然后在右乘四元数的逆，这样旋转不是转回原来的位置，而是继续保持第一次旋转的方向继续旋转。（在四维空间里面，左乘一个数采用右手法则确定旋转方向，右乘一个数则采用左手法则）其实这也就是为什么，四元数公式里面使用的是半角，而不是全角，因为我们要旋转两次。
