[. . . ] · Adding DEF Names to Part Transforms In the VRML file, assign a unique name for each VRML object. To do this, add the DEF Object_Name statement to each part Transform line. The following is an example of a VRML file that has DEF names added to the cylinder assembly. 5-47 5 Virtual Worlds Do not adjust parts in the scene that you do not want to control from the MATLAB environment. · Scaling of VRML Objects To convert CATProduct size from millimeters to meters (VRML default units), the CATIA software wraps the transform corresponding to the CATProduct with an additional transform. In this transform, the scale field is defined. If you have a small object, or an object that you must place into an overall virtual scene, adjust this scale. If you leave the VRML object scale in the default state, the local part coordinates are still in millimeters. Remember this fact when controlling these parts from the MATLAB or Simulink environment. If your MATLAB or Simulink model units are meters, scale each part individually to achieve 5-48 Using CAD Models with the Simulink® 3D AnimationTM Product correct results. You can do this by deleting the scale field from the top level transform, and adding it to each individual part transform. For example, Transform { children [ DEF CylinderAssembly1 Transform { children [ DEF CrankAssembly1 Transform { scale 0. 001 0. 001 0. 001 . . } 5-49 5 Virtual Worlds 5-50 6 Viewing Virtual Worlds After you create a virtual world in VRML (as described in Chapter 5, "Virtual Worlds"), you can visualize that virtual world with the Simulink 3D Animation viewer or with a VRML-enabled Web browser. The product includes its own viewer as the default for all supported platforms. It is the preferred method of viewing virtual worlds. For PC platforms, the product also includes a VRML plug-in (blaxxun Contact) that you can use as an alternative viewer for virtual worlds. A basic understanding of these tools and how to use them will help you to get started quickly. · "Simulink® 3D Animation Viewer" on page 6-2 · "blaxxun Contact VRML Plug-In" on page 6-50 · "Viewing Virtual Worlds with the Legacy Simulink® 3D Animation Viewer" on page 6-56 6 Viewing Virtual Worlds Simulink 3D Animation Viewer In this section. . .

You can use this viewer on any supported operating system. For a list of supported operating systems, see "System Requirements" on page 2-6. It provides a number of capabilities, including: · Treat the viewer window like a MATLAB figure. This ability enables you to perform MATLAB figure actions such as dock the viewer window in the MATLAB Command Window. [. . . ] This property acts as the master recording switch. Start and stop times for scheduled animation recording. Corresponds to the virtual world object Time property. If the virtual world is enabled for remote viewing, it is set to 'on'; otherwise, it is set to 'off'. [. . . ]
