void QMatrix4x4:: flipCoordinates ()

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

QGenericMatrix < N , M , float > qGenericMatrixFromMatrix4x4 (const QMatrix4x4 & matrix )

Returns a NxM generic matrix constructed from the left-most N columns and top-most M rows of matrix . If N or M is greater than 4, then the remaining elements are filled with elements from the identity matrix.

QMatrix4x4 qGenericMatrixToMatrix4x4 (const QGenericMatrix < N , M , float > & matrix )

Returns a 4x4 matrix constructed from the left-most 4 columns and top-most 4 rows of matrix 。若 matrix has less than 4 columns or rows, the remaining elements are filled with elements from the identity matrix.
