Inverse transformation of an axis

Hello, I have one very simple question: suppose I have an axis defined by the vector ax+by+cz. Now what will be its inverse? Is it -ax -by -cz?


Thanks.

Yes.
But what does it have to do with the Graphics Programming? :rolleyes:

As this isn't specific to c++ programming, you might get better guidance if you posted to the Algorithm forum.
