(To be removed) Add existing node to current virtual reality world

Simulink 3D Animation Viewer used by addNode has been removed. Aero.VirtualRealityAnimation does not open or play animations. Use sim3d classes in Unreal Engine 3d Environment to create and view a 3D environment instead. For more information on transitioning to the new 3D environment, see Transition Aero.VirtualRealityAnimation to Unreal Engine 3D Environment.

Syntax

addNode(h,node_name,wrl_file)


Description

addNode(h,node_name,wrl_file) adds a new node named node_name, which contains (or points to) the wrl_file. It creates a node object on the world of type Transform and adds an existing node, node_name, to the current virtual reality world.

The addNode method adds all the objects in the .wrl file to the virtual reality animation object under one node. If you want to add separate nodes for the objects in the .wrl file, place each node in a separate .wrl file.

Define the vrnode object associated with the node object using a DEF statement in the .wrl file.

Input Arguments

h — Virtual reality animation object

Aero.VirtualRealityAnimation object

Virtual reality animation object, specified as an Aero.VirtualRealityAnimation object.

node_name — vrworld node name

character vector | string

vrworld node name, specified as a character vector or string. This name must be unique from other node names in the same .wrl file. The wrl_file must contain the node to be added.

Data Types: char | string

wrl_file — .wrl file

character vector | string

The wrl_file is the VRML file from which the new node is taken. wrl_file must contain the node to be added. You must specify the full path for this file.

Data Types: char | string

Examples

Add Node to World

This example shows how to add a node to the world defined in chaseHelicopter.wrl.

h = Aero.VirtualRealityAnimation;
h.VRWorldFilename ='asttkoff.wrl';
initialize(h);
addNode(h,'Lynx','chaseHelicopter.wrl');
