3D Network Visualizer
Objective
3D Network Visualizer (3DNV) functionality lets you create three-dimensional animations based on topology information, node relationships, performance statistics, and terrain data. Y ou can, for example, use 3DNV to visualize network characteristics such as node placement, line-of-sight restrictions, transmission quality, throughput, delay, and message status information.
This tutorial provides a quick introduction to 3DNV. It shows how you can use 3DNV to do the following tasks:通古斯人
•Prepare a model for 3D animation.
•View 3D animation of a network model in the Modeler workspace (planning mode).
•View 3D animation of a simulation in progress (simulation mode).铁岭大葱
•Save and replay a 3D animation.
Before You Begin
T o do this tutorial, you must have the following licenses available:
•Modeler
•3D Network Visualizer GUI
•T errain Modeling Module
•Wireless
uc3907•Discrete Event Simulation
In addition, because OpenFlight terrain is not supported on Linux, you can do this tutorial only on Windows platforms.
Y ou should have the following software and hardware installed on your computer:
•Modeler 14.0 or later
道家导引术
•3D Network Visualizer 2.1.0
•3DNV Communications 2.1.0 (must be installed on every computer running either Modeler or
3DNV)
•128-bit video card with at least 128MB of video memory
This tutorial assumes you have a basic knowledge of how to use Modeler to configure nodes and run simulations.
Note—If you have problems with any of the 3DNV programs during this tutorial, read the T roubleshooting section at the end of this tutorial.
Configuring Modeler
Before beginning this tutorial, you must configure Modeler by setting three preference values.
1 Start Modeler.
2 Choose Edit> Preferences…
➥The Preferences dialog box opens.
3 The 3DNV tutorial network uses custom icons.
Set the Icon Databases preference to specify their location, as follows:
3.1Go to the Icon Databases preference and
click in its Value cell.
➥The Icon Databases dialog box opens.
3.2Click the Insert button, type
wireless_corps, and press <Enter> to
accept the value.
3.3Click OK to accept the changes and close
the Icon Databases dialog box.
4 The 3DNV tutorial uses custom node models. Set
Modeler to recompile models by removing any
references to existing model repositories:
4.1Go to the Network Simulation
Repositories preference.
4.2If the preference value is not (), click in the
Value cell, delete all repository names, and
close the Network Simulation Repositories
dialog box.
5 The 3DNV tutorial uses the same terrain
database in Modeler and the
3D Network Visualizer. T o ensure that 3D
positions are in synch between the two programs, Modeler needs to use an ellipsoid representation of Earth similar to the one used in the
3D Network Visualizer. This replaces the default spherical model (which is faster to compute):
5.1Go to the Earth Geocentric Model
马鸣春
preference.
5.2If the preference value is not ellipsoid, click
in the Value cell and choose ellipsoid.
6 Click OK to close the Preferences dialog box.
➥A dialog box appears indicating that the Earth Geocentric Model and Icon Databases
preferences require the tool to be restarted for
the changes to be taken into account. Click OK
to dismiss this dialog box.
7 Quit and restart Modeler to make the icons
available and to use the ellipsoid earth model. Using Multiple Computers
The 3DNV module can be installed on the computer running Modeler or on a different computer. A different computer (as shown in the following figure) is recommended for best performance.
