An ordered collection of nodes is referred to as a scene graph. OpenInventor takes care of storing and managing one or more scene graphs in the database. On such a scene graph you can apply a number of operations or actions, including rendering, picking, searching, computing a bounding box, and writing to a file. When an action is applied to a node, the graph rooted by that node is traversed from left to right. When using the SSL a specific program, that allows clients to connect to servers using any available ports the portmaster , must be started on the machines running the display server and the visualization server.
Servers register themselves with a name to the portmaster running on the same machine.
Then the clients can access the server they want to communicate with by opening a connection using the server s name, without knowing the specific port number. The AVS-system allows users to interactively connect software modules to create data flow networks for scientific visualization. Modules tell the AVS Kernel what kind of data they expect to receive from other modules at their input ports and what kind of data they supply at their output ports. These output ports can be connected to other modules that have compatible input ports. Because AVS operates on fairly general data types, you can define new modules to work with existing modules.
