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.

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. |
virtual HBaseOperator* HOpCameraZoomTouch::Clone | ( | ) | [virtual] |
Creates a new operator which is a copy of the current operator. The user is responsible for deleting the newly created operator.
Reimplemented from HBaseOperator.
bool HOpCameraZoomTouch::GetLightFollowsCamera | ( | ) | [inline] |
virtual const char* HOpCameraZoomTouch::GetName | ( | ) | [virtual] |
Reimplemented from HBaseOperator.
virtual int HOpCameraZoomTouch::OnTouchesDown | ( | HEventInfo & | hevent | ) | [virtual] |
OnTouchesDown records touch positions and calculates the current camera target based on the first touch points.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
virtual int HOpCameraZoomTouch::OnTouchesMove | ( | HEventInfo & | hevent | ) | [virtual] |
OnTouchesDownAndMove zooms the camera in and out based on a pinching motion of the user.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
virtual int HOpCameraZoomTouch::OnTouchesUp | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonUp updates the scene with current camera and lighting information and cleans up.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
void HOpCameraZoomTouch::SetLightFollowsCamera | ( | bool | follow | ) | [inline] |
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. |
