HOpCameraOrbit 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:
HOpCameraOrbit::HOpCameraOrbit | ( | HBaseView * | view, | |
int | DoRepeat = 0 , |
|||
int | DoCapture = 1 | |||
) |
Constructs an HOpCameraOrbit 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* HOpCameraOrbit::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.
Reimplemented in HOpCameraRelativeOrbit.
bool HOpCameraOrbit::GetLightFollowsCamera | ( | ) | [inline] |
virtual const char* HOpCameraOrbit::GetName | ( | ) | [virtual] |

bool HOpCameraOrbit::GetSingleClick | ( | ) | [inline] |
virtual int HOpCameraOrbit::OnLButtonDown | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonDown draws a bounding box around the scene, records the mouse position, and maps the mouse position to spherical coordinates.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
Reimplemented in HOpCameraRelativeOrbit.
virtual int HOpCameraOrbit::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 if you have set the light to follow the camera.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
Reimplemented in HOpCameraRelativeOrbit.
virtual int HOpCameraOrbit::OnLButtonUp | ( | HEventInfo & | hevent | ) | [virtual] |
OnLButtonUp updates the scene with the most recent camera and lighting information and cleans up.
hevent | An HEventInfo object containing information about the current event. |
Reimplemented from HBaseOperator.
void HOpCameraOrbit::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. |
void HOpCameraOrbit::SetSceneBoundingBoxVis | ( | bool | vis | ) | [inline] |
SetSceneBoundingBoxVis controls whether a bounding box denoting the scene extents should be drawn during a camera orbit.
vis | Pass true if you want HOOPS to draw the bounding box or false if you don't. |

bool HOpCameraOrbit::m_bLightFollowsCamera [protected] |
This member indicates whether the light should follow the camera.
bool HOpCameraOrbit::m_bSceneBoundingBoxVis [protected] |
This member indicates whether a bounding box denoting the scene extents should be drawn during a camera orbit.
bool HOpCameraOrbit::m_bSingleClick [protected] |
This member indicates whether the mouse has moved in between lbuttondown/lbuttonup.
