Why does my animation sometimes get partly blacked out during simulation

 NavigationInfo {

   visibilityLimit 100000

   speed 1000

   headlight FALSE

   avatarSize [10, 1.6, 0.75 ]

 }

In the above example, 'visibilityLimit' defines the far clipping plane. A large value assures that all objects that are closer are visible. The near clipping plane is set to 1/2 of the first component of the 'avatarSize' field. Hence by setting the 'avatarSize' value to 10m, we are setting the near clipping plane to 5 m. For more information on Binding nodes such as the 'NavigationInfo' node, see the VRML97 standard:

There is another resource with annotated VRML Documentation that is available in the URL below.

Animation is cached during model simulation. What you see when you run a simulation is the animation playback, unless the simulation is slower than the animation caching. In that case, the animation goes no faster than the simulation can produce the cache.

Once a partial or complete animation is cached from simulation, starting the animation again plays back the cache, without running the simulation a second time. You can move backward and forward to any time in the cached animation.

The animation cache is stored until you close Mechanics Explorer. When you simulate the model, the cache is updated with new animation data. To create a permanent record of a model animation, you must create an animation video
