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

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

◆ Rotate()

void open3d::visualization::rendering::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::rendering::ModelInteractorLogic, open3d::visualization::rendering::LightDirectionInteractorLogic, open3d::visualization::rendering::IBLRotationInteractorLogic, open3d::visualization::rendering::CameraSphereInteractorLogic, and open3d::visualization::rendering::CameraInteractorLogic.

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