Example 2 with Node

use of org.graphstream.graph.Node in project gs-ui-javafx by graphstream.

the class DefaultCamera method checkVisibility.

 * Process each node to check if it is in the actual view port, and mark
 * invisible nodes. This method allows for fast node, sprite and edge
 * visibility checking when drawing. This must be called before each
 * rendering (if the view port changed).
