Navigation Settings

• Navigation mode
  This allows you to select the navigation mode from a list of available navigation paradigms.



• Travel speed
  Sets the rate at which the viewer travels through a scene. The following are the typical values for the rates, in metres per second: Slowest=0.0625, Slower=0.25, Normal=1, Faster=4, Fastest=16. If the speed field of the NavigationInfo is specified in the VRML file, the corresponding speed factors are multiplied.



• Animate viewpoint
  Sets the Viewpoint transition rules that specify how Cortona interprets the transition from the old viewpoint to the new one. Auto – defined by the jump field of the Viewpoint node of a new location. Always – a jump with the transition effect. Never – instantaneous transition.



• Collision detection
  By default Cortona (used as a 3D viewer) will allow you to pass through objects in your path. To prevent from passing through objects, select Always in the Collision detection box at the Navigation tab. Select Auto to use the collision method specified by VRML author.



• Headlight on
  Mark the check box to turn the headlight on.



• Show hidden viewpoint
  This allows you to see all viewpoints of the scene in the Viewpoints list including those that do not have a description (Viewpoint's description field is empty).
