HOpCameraRelativeOrbit implements three mouse event methods defined on the base class and maps the event information to the HOOPS routine HC_Orbit_Camera. This operation consists of the following steps:
HOpCameraRelativeOrbit::HOpCameraRelativeOrbit | ( | HBaseView * | view, | |
int | doRepeat = 0 , |
|||
int | doCapture = 1 | |||
) |
Constructs an HOpCameraRelativeOrbit 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* HOpCameraRelativeOrbit::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 HOpCameraOrbit.
HPoint HOpCameraRelativeOrbit::GetCenter | ( | ) |
Get center point for camera rotation
virtual const char* HOpCameraRelativeOrbit::GetName | ( | ) | [virtual] |
Reimplemented from HOpCameraOrbit.
virtual int HOpCameraRelativeOrbit::OnLButtonDown | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDown draws a bounding box around the scene, records the mouse position, and maps the mouse position to spherical coordinates around the clicked object.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HOpCameraOrbit.
virtual int HOpCameraRelativeOrbit::OnLButtonDownAndMove | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDownAndMove records points as the mouse is moved, maps the points to spherical coordinates, and calculates the appropriate values for HC_Orbit_Camera and HC_Roll_Camera. 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 HOpCameraOrbit.
void HOpCameraRelativeOrbit::SetCenter | ( | HPoint | center | ) |
Sets the center point for camera rotation.
c | The center point for the camera rotation. |
