void QMatrix4x4::flipCoordinates()

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.

参见 QMatrix4x4::toGenericMatrix().

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. If matrix has less than 4 columns or rows, the remaining elements are filled with elements from the identity matrix.
