public class SoVRMLGeoViewpoint extends SoVRMLViewpoint
SoVRMLGeoViewpoint node defines a specific location in a local geospatial coordinate system from which the user might view the scene.
This section describes the expected behavior of the node in a conforming X3D / VRML97 browser application. In some cases, the application is responsible for implementing portions of the expected behavior. Open Inventor viewer classes and IVF classes implement some of the application behaviors.
This section may reference portions of the X3D specification that are not present in this help file. The complete X3D spec is available at
SoVRMLGeoViewpoint node allows the specification of a viewpoint in terms of a geospatial coordinate. This node can be used wherever a Viewpoint node can be used and can be combined with Viewpoint nodes in the same scene. The
isBound fields and events have the same behavior as the standard Viewpoint node. When a
SoVRMLGeoViewpoint node is bound, it overrides the currently bound Viewpoint and NavigationInfo nodes in the scene. The
geoOrigin field is used to specify a local coordinate frame for extended precision as described in 25.2.5 Dealing with high-precision coordinates. The
geoSystem field is used to define the spatial reference frame and is described in 25.2.3 Specifying a spatial reference frame. The
position is used to define the actual coordinate at which the viewpoint is to be located. It should be provided in a format consistent with that specified by geoSystem. There is also a set_position field which can be routed from the geovalue_changed field of a GeoPositionInterpolator node in order to animate the position of the
orientation string defines a relative orientation from the local orientation frame that is defined by the
position field. By default, the orientation of the viewpoint will always be aligned such that the +Y axis is the up vector for the local area (the normal to the tangent plane on the ellipsoid), -Z points towards the north pole, and +X is east. Therefore, if a
SoVRMLGeoViewpoint is created that always looked straight down, no matter where on the planetary body is being observed, an orientation value of [ 1 0 0 -1.57 ] is used. The set_orientation field can be routed to the value_changed field of an OrientationInterpolator in order to animate the orientation of the
navType field is used to specify the navigation type that is to be bound when this
SoVRMLGeoViewpoint node is bound. The acceptable values for this field are the same as those for the type field of the NavigationInfo node. The
headlight field is used to specify the whether the viewer shall turn on a headlight when this viewpoint is bound. A headlight is a directional light that always points in the direction that the user is looking. The
SoVRMLGeoViewpoint node may be implemented as if there is an embedded NavigationInfo node that is bound and unbound with the
SoVRMLGeoViewpoint node. The
speedFactor field of the
SoVRMLGeoViewpoint node is used as a multiplier to the elevation-based velocity that the node sets internally; i.e., this is a relative value and not an absolute speed as is the case for the NavigationInfo node.
