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:
HOpCameraPan::HOpCameraPan | ( | HBaseView * | view, | |
int | DoRepeat = 0 , |
|||
int | DoCapture = 1 | |||
) |
Constructs an HOpCameraPan 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* HOpCameraPan::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 HOpCameraPan::GetLightFollowsCamera | ( | ) | [inline] |
virtual const char* HOpCameraPan::GetName | ( | ) | [virtual] |
Reimplemented from HBaseOperator.
virtual int HOpCameraPan::OnLButtonDown | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDown records the initial mouse position.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
virtual int HOpCameraPan::OnLButtonDownAndMove | ( | HEventInfo & | hevent | ) | [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.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
virtual int HOpCameraPan::OnLButtonUp | ( | 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 HOpCameraPan::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. |
