### 9.6.1 Changing handedness?

"How can I set Moray to use the same handedness as POV-Ray? How can I set POV-Ray to use the same handedness as Moray?"

The answer to the first question is: You can't.

But you can change the handedness in POV-Ray. By default POV-Ray uses a left-handed system. You can change it to right-handed by adding the following keyword to the camera definition:

      right <-4/3,0,0>

Now you can use coordinates like in Moray, with x pointing to the right, y pointing "inside" the screen and z pointing up.

This keyword also controls the aspect ratio of the image.
