DESCRIPTION
The Examiner viewer component allows you to rotate the view around a point of interest using a virtual trackball. The viewer uses the camera focalDistance field to figure out the point of rotation, which is usually set to be at the center of the scene. In addition to allowing you to rotate the camera around the point of interest, this viewer also allows you to translate the camera in the viewer plane, as well as dolly (move forward and backward) to get closer to or further away from the point of interest. The viewer also supports seek to quickly move the camera to a desired object or point.

METHODS

SoXtExaminerViewer(Widget parent = NULL, const char *name = NULL, SbBool buildInsideParent = TRUE, SoXtFullViewer::BuildFlag flag = BUILD_ALL, SoXtViewer::Type type = BROWSER)

~SoXtExaminerViewer()
Constructor and destructor which specifies the viewer type. Please refer to the SoXtViewer reference page for a description of the viewer types.

void
setFeedbackVisibility(SbBool onOrOff)
SbBool
isFeedbackVisible() const
Show/Hide the point of rotation feedback, which only appears while in viewing mode (default in off).

void
setFeedbackSize(int newSize)
int
getFeedbackSize() const
Set/get the point of rotation feedback size in pixels (default 20 pix).

void
setAnimationEnabled(SbBool onOrOff)
SbBool
isAnimationEnabled()
Enable/disable the spinning animation feature of the viewer (enabled by default).

void
stopAnimating()
SbBool
isAnimating()
Stop animation, if it is occurring, and query if the viewer is currently animating.

RESOURCES

*SoXtExaminerViewer.spinAnimation: on (on | off)
*SoXtExaminerViewer.pointOfRotationAxes: off (on | off)
*SoXtExaminerViewer.axesSize: 20 (short, pixels if axes is on)
*SoXtExaminerViewer.decoration: on (on | off)
*SoXtExaminerViewer.seekAnimationTime: 2.0 (float)
*SoXtExaminerViewer.seekTo: point (point | object)
*SoXtExaminerViewer.seekDistanceUsage: percentage (percentage | absolute)
*SoXtExaminerViewer.zoomMin: 1.0 (float)
*SoXtExaminerViewer.zoomMax: 179.0 (float)
*SoXtExaminerViewer.autoClipping: on (on | off)
*SoXtExaminerViewer.nearDistance: 2.4 (float, when autoClipping is off)
*SoXtExaminerViewer.farDistance: 2.8 (float, when autoClipping is off)
*SoXtExaminerViewer*BackgroundColor: black (color name or hex value)

USAGE

Left Mouse: Rotate the virtual trackball.

Middle Mouse:
Ctrl + Left Mouse: Translate up, down, left and right.

Ctrl + Middle Mouse:
Left + Middle Mouse: Dolly in and out (gets closer to and further
away from the object).

<s> + click: Alternative to the Seek button. Press (but do not
hold down) the <s> key, then click on a target object.

Right Mouse: Open the popup menu.
