Request by the client for an EnSight scene update.

This [SceneClientCommand](structensightservice_1_1_scene_client_command.xhtml "Aggregate command sent by a dynamic scene graph client.") sub message is sent by the client at startup or whenever the client would like a scene update. The server will respond by starting a scene update command sequence, beginning with a [SceneUpdateCommand](structensightservice_1_1_scene_update_command.xhtml "Aggregate command sent by EnSight to a client.") message, [UpdateSceneBegin](structensightservice_1_1_update_scene_begin.xhtml "Begin an update sequence.") sub command. The update sequence will end with a [SceneUpdateCommand](structensightservice_1_1_scene_update_command.xhtml "Aggregate command sent by EnSight to a client.") message, [UpdateSceneEnd](structensightservice_1_1_update_scene_end.xhtml "End an update sequence.") sub command.

This message also informs the server what the maximum size of a block of data should be (in bytes). It also can be used to enable "spontaneous" scene updates that can be started by the EnSight server at any time. If the client would like the server to rebroadcast the entire scene, it should set the allow\_incremental\_updates flag to false, suppressing state cache tracking by the server.
