Member Function Documentation

[override virtual noexcept] TransformationMatrix::~TransformationMatrix()

Destructor.

Esri::ArcGISRuntime::TransformationMatrix *TransformationMatrix::addTransformation(Esri::ArcGISRuntime::TransformationMatrix *matrix, QObject *parent = nullptr) const

Adds another transformation matrix to this transformation matrix and returns the result.

Returns nullptr if matrix is nullptr.

• matrix - The matrix to add.
• parent - The parent QObject (optional).

[static] Esri::ArcGISRuntime::TransformationMatrix *TransformationMatrix::createIdentityMatrix(QObject *parent = nullptr)

Creates a TransformationMatrix object with an identity matrix.

• parent - The parent QObject (optional).

This TransformationMatrix will have no transformation. The values are (0, 0, 0, 1) for x, y, z, w quaternion and (0, 0, 0) for x, y, z translations.

Subtracting a TransformationMatrix from an identity matrix is useful for getting the inverse of that transformation matrix, i.e. identity matrix - other matrix = inverse(other matrix) return_description: A TransformationMatrix.

[static] Esri::ArcGISRuntime::TransformationMatrix *TransformationMatrix::createWithQuaternionAndTranslation(double quaternionX, double quaternionY, double quaternionZ, double quaternionW, double translationX, double translationY, double translationZ, QObject *parent = nullptr)

Creates a transformation matrix using x, y, z, w quaternion and x, y, z translations.

• quaternionX - The x quaternion of the transformation matrix.
• quaternionY - The y quaternion of the transformation matrix.
• quaternionZ - The z quaternion of the transformation matrix.
• quaternionW - The w quaternion of the transformation matrix.
• translationX - The x position of the transformation matrix.
• translationY - The y position of the transformation matrix.
• translationZ - The z position of the transformation matrix.
• parent - The parent QObject (optional).

double TransformationMatrix::quaternionW() const

The w quaternion of the transformation matrix.

double TransformationMatrix::quaternionX() const

The x quaternion of the transformation matrix.

double TransformationMatrix::quaternionY() const

The y quaternion of the transformation matrix.

double TransformationMatrix::quaternionZ() const

The z quaternion of the transformation matrix.

Esri::ArcGISRuntime::TransformationMatrix *TransformationMatrix::subtractTransformation(Esri::ArcGISRuntime::TransformationMatrix *matrix, QObject *parent = nullptr) const

Subtracts a new matrix from the transformation matrix and returns the result.

Returns nullptr if matrix is nullptr.

• matrix - The matrix to substract.
• parent - The parent QObject (optional).

double TransformationMatrix::translationX() const

The x position of the transformation matrix.

double TransformationMatrix::translationY() const

The y position of the transformation matrix.

double TransformationMatrix::translationZ() const

The z position of the transformation matrix.
