Detailed Description
The HOpCameraPan class pans the camera about a current view.
HOpCameraPan implements three mouse event methods defined on the base class and maps the event information to HOOPS camera routines. This operation consists of the following steps:
- Left Button Down: The pan is initiated.
- Left Button Down and Drag: The camera pans.
- Left Button Up: The operation ends.

Constructor & Destructor Documentation
◆ HOpCameraPan()
HOpCameraPan::HOpCameraPan | ( | HBaseView * | view, |
int | DoRepeat = 0 , |
||
int | DoCapture = 1 |
||
) |
Constructs an HOpCameraPan 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
◆ 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.
◆ GetLightFollowsCamera()
|
inline |
- Returns
- True if the light follows the camera or false if it doesn't.
◆ GetName()
|
virtual |
- Returns
- A pointer to a character string denoting the name of the operator which is 'HOpCameraPan'.
Reimplemented from HBaseOperator.
◆ OnLButtonDown()
|
virtual |
OnLButtonDown records the initial mouse position.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
◆ OnLButtonDownAndMove()
|
virtual |
OnLButtonDownAndMove records points as the mouse is moved and calculates the values used for panning the camera by modifying the camera's target and position. It also updates the position of the default light, depending on whether you have set the light to follow the camera.
- Parameters
-
hevent An HEventInfo object containing information about the current event.
- Returns
- An HOperatorReturn indicating the status of the event.
Reimplemented from HBaseOperator.
◆ OnLButtonUp()
|
virtual |
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.
Reimplemented from HBaseOperator.
◆ SetLightFollowsCamera()
|
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.
