public interface UpdatableNode

Node updater interface is designed to allow special code to adjust a node's appearance if it is going to be rendered. This should *not* be used to adjust a transform since these methods are only called if the renderer has determined that the node is within view. This is a way of adjusting display only when necessary. An example would be a particle system, where you only want to acutally adjust the geometry if the particle system is within view.

               org.openmali.spatial.bodies.Frustum frustum,
               long nanoTime,
               long nanoStep)

Parameters:

view - the view that's currently used for rendering

frustum - view frustum

nanoTime -

nanoStep -

Returns:

True if this should be rendered, false if it should not.
