The HOpCameraZoomTouch class zooms the camera toward a target.
HOpCameraZoomTouch implements three of the touch handlers defined on the base class and maps the event information to HOOPS camera routines based on a two finger pinching motion. This provides the basic functionality for interactively zooming in or out from a model in realtime.
More Detailed Description: see event methods.
HOpCameraZoomTouch::HOpCameraZoomTouch | ( | HBaseView * | view, |
int | DoRepeat = 0 , |

int | DoCapture = 1 |

) |
Constructs an HOpCameraZoomTouch object.
view | A pointer to an HBaseView object. |
DoRepeat | An integer denoting whether this is a repeatable operator. This parameter has been deprecated. |
DoCapture | An integer denoting whether the mouse state should be captured, which means that all mouse events should be received after a mousedown, even if it leaves the window. This parameter has been deprecated. |

SetLightFollowsCamera sets the lights to follow the camera or to stay in one place during orbit. This has the effect of either lighting the scene during orbit or allowing the camera to move through shadow. The default is off.
follow | Pass true to have the light follow the camera. |
