Detailed Description

The HOpCameraRollTouch class rolls the camera around the current view axis.

HOpCameraPan implements three mouse event methods defined on the base class and maps the event information to HOOPS camera routines based on two finger input. More Detailed Description: see event methods


Constructor & Destructor Documentation

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

Constructs an HOpCameraRollTouch object.

Parameters:
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.


Member Function Documentation

virtual HBaseOperator* HOpCameraRollTouch::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 HOpCameraRollTouch::GetLightFollowsCamera (  )  [inline]

Returns:
True if the light follows the camera or false if it doesn't.

virtual const char* HOpCameraRollTouch::GetName (  )  [virtual]

Returns:
A pointer to a character string denoting the name of the operator which is 'HOpCameraPan'.

Reimplemented from HBaseOperator.

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

OnTouchesDown records the initial touch position.

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

Reimplemented from HBaseOperator.

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

OnTouchesMove records two touch points and rolls the camera around the view axis based on a circular touch motio

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

Reimplemented from HBaseOperator.

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

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

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

Reimplemented from HBaseOperator.

void HOpCameraRollTouch::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:
follow Pass true to have the light follow the camera.
