Detailed Description

class HOpCameraPanTouch : public HBaseOperator 

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

Public Functions

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

Constructs an HOpCameraPanTouch 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.

virtual ~HOpCameraPanTouch()

virtual char const *GetName()

Returns: A pointer to a character string denoting the name of the operator, which is ‘HOpCameraPanTouch’.

virtual int OnTouchesDown(HEventInfo &hevent)

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.

virtual int OnTouchesMove(HEventInfo &hevent)

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

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

virtual int OnTouchesUp(HEventInfo &hevent)

OnLButtonUp 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.

inline void SetLightFollowsCamera(bool follow)

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.

inline bool GetLightFollowsCamera()

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

virtual HBaseOperator *Clone()

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.
