DESCRIPTION¶

The paradigm for this viewer is a walkthrough of an architectural model. Its primary behavior is forward, backward, and left/right turning motion while maintaining a constant "eye level". It is also possible to stop and look around at the scene. The eye level plane can be disabled, allowing the viewer to proceed in the "look at" direction, as if on an escalator. The eye level plane can also be translated up and down — similar to an elevator.

METHODS¶

SoXtWalkViewer(Widget parent = NULL, const char *name = NULL, SbBool buildInsideParent = TRUE, SoXtFullViewer::BuildFlag flag = BUILD_ALL, SoXtViewer::Type type = BROWSER)
~SoXtWalkViewer()
Constructor and destructor which specifies the viewer type. Please refer to the SoXtViewer man pages for a description of the viewer types.

RESOURCES¶

*SoXtWalkViewer.decoration: on (on | off)
*SoXtWalkViewer.seekAnimationTime: 2.0 (float)
*SoXtWalkViewer.seekTo: point (point | object)
*SoXtWalkViewer.seekDistanceUsage: percentage (percentage | absolute)
*SoXtWalkViewer.zoomMin: 1.0 (float)
*SoXtWalkViewer.zoomMax: 179.0 (float)
*SoXtWalkViewer.autoClipping: on (on | off)
*SoXtWalkViewer.nearDistance: 2.4 (float, when autoClipping is off)
*SoXtWalkViewer.farDistance: 2.8 (float, when autoClipping is off)
*SoXtWalkViewer*BackgroundColor: black (color name or hex value)

USAGE¶

Left Mouse: walk mode. Click down and move up/down for fowards/backwards motion. Move right and left for turning. Speed increases exponentially with the distance from the mouse-down origin. Middle Mouse - or Ctrl + Left Mouse: Translate up, down, left and right. Ctrl + Middle Mouse: tilt the camera up/down and right/left. This allows you to look around while stopped. <s> + click: Alternative to the Seek button. Press (but do not hold down) the <s> key, then click on a target object. <u> + click: Press (but do not hold down) the <u> key, then click on a target object to set the "up" direction to the surface normal. By default +y is the "up" direction. Right Mouse: Open the popup menu.
