Dolly() [1/2]

void open3d::visualization::MatrixInteractorLogic::Dolly ( int  dy, DragType  drag_type  )

virtual

Moves the matrix along the forward axis. (This is one type of zoom.)

Reimplemented in open3d::visualization::ModelInteractorLogic, and open3d::visualization::CameraInteractorLogic.

Dolly() [2/2]

void open3d::visualization::MatrixInteractorLogic::Dolly ( float  z_dist, Camera::Transform  matrix  )

Rotate()

void open3d::visualization::MatrixInteractorLogic::Rotate ( int  dx, int  dy  )

virtual

Rotates about an axis defined by dx * matrixLeft, dy * matrixUp. dy is assumed to be in window-style coordinates, that is, going up produces a negative dy. The axis goes through the center of rotation.

Reimplemented in open3d::visualization::ModelInteractorLogic, open3d::visualization::LightDirectionInteractorLogic, open3d::visualization::IBLRotationInteractorLogic, and open3d::visualization::CameraInteractorLogic.

RotateWorld()

void open3d::visualization::MatrixInteractorLogic::RotateWorld ( int  dx, int  dy, const Eigen::Vector3f &  x_axis, const Eigen::Vector3f &  y_axis  )

virtual

Same as Rotate() except that the dx-axis and the dy-axis are specified

RotateZ()

void open3d::visualization::MatrixInteractorLogic::RotateZ ( int  dx, int  dy  )

virtual

Rotates about the forward axis of the matrix.

Reimplemented in open3d::visualization::ModelInteractorLogic, open3d::visualization::IBLRotationInteractorLogic, and open3d::visualization::CameraInteractorLogic.

RotateZWorld()

void open3d::visualization::MatrixInteractorLogic::RotateZWorld ( int  dx, int  dy, const Eigen::Vector3f &  forward  )

virtual

SetBoundingBox()

void open3d::visualization::MatrixInteractorLogic::SetBoundingBox ( const geometry::AxisAlignedBoundingBox &  bounds )
