Interact with Virtual Reality Worlds

与MATLAB创建和互动^®虚拟世界对象，输入虚拟世界数据金宝app^®模型s

您可以使用MATLABfunctions and classes to interact with virtual reality worlds. Create a virtual world object (vrobject）和节点对象（VRNODE）代表您创建的虚拟世界金宝appSimulink 3D动画™. Change and control the degrees of freedom for the virtual world from within the MATLAB environment by setting values for the available virtual world nodes and their fields usingVRNODEobject methods.

虚拟现实场景可以包含传感器，这些传感器是根据时间，导航以及动作以及场景中的距离变化生成事件和输出值的节点。这些节点为虚拟世界增添了交互性。您可以使用金宝appSimulink 3D动画functions to read sensor field values into simulation models and control simulation based on the user interaction with the virtual scene. You can write an S-function or aMATLAB功能读取传感器输出的块。

Virtual Reality World and Dynamic System Examples

Use virtual worlds that interface to Simulink block diagrams and to MATLAB objects and functions.

为虚拟世界创建vrworld对象

将MATLAB连接到虚拟世界，并通过创建VRWORLD和VRNODE对象通过MATLAB命令行界面与该虚拟世界交互。

用Matlab打开虚拟世界

Open a virtual world to view the virtual world in a virtual world viewer, scan its structure, and change virtual world properties from the MATLAB Command Window.

与MATLAB与虚拟世界互动

Interact with virtual world by using vrnode object methods to set vrworld object property values for all the available virtual world nodes and their fields.

关闭和删除一个vrworld对象

关闭虚拟世界并将其从内存中删除。

虚拟世界数据类型

探索节点用于定义对象的数据类型以及可以出现在节点字段和事件中的数据类型。

VRML传感器输入到模型

使用传感器

基于虚拟世界或虚拟世界中事件的用户输入，在仿真过程中移动或修改虚拟世界对象。

Modify Remote Virtual World Via Sensor Events

Interactive mode allows clients to modify a remote virtual world via events from sensor nodes defined in the virtual world.

检测对象碰撞

使用碰撞检测来避免让两个对象碰撞，或触发虚拟世界对象行为或显示的更改。

Portal Crane with Joystick Control

The vrcrane_joystick example illustrates how a Simulink® model can interact with a virtual world. The portal crane dynamics is modeled in Simulink and visualized in virtual reality. The model uses Joystick Input block to control the setpoint. Joystick 3 axes are used to control the setpoint position, button 1 is used to start the crane.

Inverted Pendulum

的vrpend服务le illustrates the various ways a dynamic model in Simulink® can interact with a virtual reality world. It is the model of 2-dimensional inverted pendulum controlled by a PID controller. What distinguishes this model from 'common' inverted pendulum models is visualization and the methods of setting the setpoint. You visualize and interact with a virtual world by using a Trajectory Graph and VR Sink blocks. The Trajectory Graph block allows you to track the history of the pendulum position and change the setpoint. The method for setting the setpoint can be selected in the mask of the Trajectory Graph block. The following methods are available:

虚拟控制面板

Vrdemo_panel example shows the use of sensing objects that are available in the 3D World Editor Components library. These objects combine VRML sensors whose values can be read into Simulink® by the VR Source block with logic (implemented using VRML Scripts and Routes) that changes their visual appearance based on user input.
