Member Function Documentation

◆ Rotate()

void cloudViewer::visualization::rendering::CameraSphereInteractorLogic::Rotate ( int  dx,
int  dy 
)
overridevirtual

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 from cloudViewer::visualization::rendering::CameraInteractorLogic.
