Tutorial I
Running a model with 3D animation
Accommodations for the 3D world
The model has been specifically adapted to animate in the E3D window in Concurrent anima- tion mode. The differences between this model and a standard discrete event model are:
• 3DobjectshavebeenselectedintheItemAni- mation and Block Animation tabs of Item library blocks. For instance, each passenger is a Ran- dom person, as shown in the Create block’s Item Animation tab at the right. (You won’t be able to see these selections unless you have the E3D window open.)

• SeveralTransportblockshavebeenaddedto
animate real-time delays in item movement. These are placed between other Item library blocks so the E3D window will know how far the item travels from one block/object to another and how long it will take the item to get there. So that delays in movement are real- istically represented, this information is used as part of the conversion of simulation time in the 2D model to animation time in the E3D window.
• Amongothertasks,Animate3D blocks (Animation 2D-3D library) within hierarchical blocks are used to create pieces of luggage that are then “mounted” to each passenger.
• 3D Text blocks (Animation 2D-3D
library) have been placed in the model at various locations to serve as labels in the E3D win- dow. For instance, a 3D Text block places the label “Passport Control” at the appropriate location in the 3D window.

☞ Notice that no programming was required to adapt this model for 3D animation. The only accommodations were the addition of some animation-specific blocks, the selection of 3D options in block Item Animation and Block Animation tabs, and modifications to the environ- ment file.
Running the model with 3D animation
To open the E3D window and animate the model:
Give the command Window > E3D Window or click the Open E3D Window button in the toolbar
Verify that the E3D window is associated with the Airline Security model Position the E3D window in a convenient location
Animate 3D dialog - mounting luggage
