Member Function Documentation

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() does.

See also ortho().

QVector3D operator*(const QVector3D &vector, const QMatrix4x4 &matrix)

This function is deprecated since 6.1. We strongly advise against using it in new code.

Convert the QVector3D to a QVector4D first, then multiply.

Returns the result of transforming vector according to matrix, with the matrix applied post-vector. The vector is transformed as a point.

QVector3D operator*(const QMatrix4x4 &matrix, const QVector3D &vector)

This function is deprecated since 6.1. We strongly advise against using it in new code.

Use QMatrix4x4::map() or QMatrix4x4::mapVector() instead.

Returns the result of transforming vector according to matrix, with the matrix applied pre-vector. The vector is transformed as a projective point.

QPoint operator*(const QMatrix4x4 &matrix, const QPoint &point)

This function is deprecated since 6.1. We strongly advise against using it in new code.

Use QMatrix4x4::map() instead.

Returns the result of transforming point according to matrix, with the matrix applied pre-point.

QPointF operator*(const QMatrix4x4 &matrix, const QPointF &point)

This function is deprecated since 6.1. We strongly advise against using it in new code.

Use QMatrix4x4::map() instead.

Returns the result of transforming point according to matrix, with the matrix applied pre-point.
