The HOpCameraOrbit class provides interactive orbiting of the camera around a scene.
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:
As the mouse moves through the scene, the 2D position of the pointer is mapped into 3D space like a trackball around the model. More Detailed Description: see event methods.
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. |

OnLButtonDown draws a bounding box around the scene, records the mouse position, and maps the mouse position to spherical coordinates.

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.

OnLButtonUp updates the scene with the most recent camera and lighting information and cleans up.

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. |
|
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. |
