void QMatrix4x4:: flipCoordinates ()

This function is deprecated. We strongly advise against using it in new code.

Flips between right-handed and left-handed coordinate systems by multiplying the y and z coordinates by -1. This is normally used to create a left-handed orthographic view without scaling the viewport as ortho () 做。

另请参阅 ortho ().
