Detailed Description

The HOpCameraPanTouch class pans the camera about a current view.

HOpCameraPanTouch implements three touch event methods defined on the base class and maps the event information to HOOPS camera routines via a two finger pinch operation. More Detailed Description: see event methods


Constructor & Destructor Documentation

HOpCameraPanTouch::HOpCameraPanTouch ( HBaseView view,
int  DoRepeat = 0,
int  DoCapture = 1 
)

Constructs an HOpCameraPanTouch object.

Parameters:
viewA pointer to an HBaseView object.
DoRepeatAn integer denoting whether this is a repeatable operator. This parameter has been deprecated.
DoCaptureAn 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.

Member Function Documentation

virtual HBaseOperator* HOpCameraPanTouch::Clone ( ) [virtual]

Creates a new operator which is a copy of the current operator. The user is responsible for deleting the newly created operator.

Returns:
A pointer to the newly created HOpCameraPan object.

Reimplemented from HBaseOperator.

bool HOpCameraPanTouch::GetLightFollowsCamera ( ) [inline]
Returns:
True if the light follows the camera or false if it doesn't.
virtual const char* HOpCameraPanTouch::GetName ( ) [virtual]
Returns:
A pointer to a character string denoting the name of the operator, which is 'HOpCameraPanTouch'.

Reimplemented from HBaseOperator.

virtual int HOpCameraPanTouch::OnTouchesDown ( HEventInfo hevent) [virtual]

OnTouchesDown records the initial touch position

Parameters:
heventAn HEventInfo object containing information about the current event.
Returns:
An HOperatorReturn indicating the status of the event.

Reimplemented from HBaseOperator.

virtual int HOpCameraPanTouch::OnTouchesMove ( HEventInfo hevent) [virtual]

OnLButtonDownAndMove records the location of the center point between two touches and pans the camera accordingly

Parameters:
heventAn HEventInfo object containing information about the current event.
Returns:
An HOperatorReturn indicating the status of the event.

Reimplemented from HBaseOperator.

virtual int HOpCameraPanTouch::OnTouchesUp ( HEventInfo hevent) [virtual]

OnLButtonUp updates the scene with current camera and lighting information and cleans up.

Parameters:
heventAn HEventInfo object containing information about the current event.
Returns:
An HOperatorReturn indicating the status of the event.

Reimplemented from HBaseOperator.

void HOpCameraPanTouch::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.

Parameters:
followPass true to have the light follow the camera.
