Exercise 1—Simulating a Dropping Coin
2.
Choose a directory to which you would like to save the file.
3.
Type COINDROP in the File name edit box.
Working Model 3D automatically adds an extension WM3 to the
filename. Therefore, the file is saved as COINDROP.WM3.
4.
Click Save.
The simulation history is saved as well as the model data. When you open
the file next time, you can click the Run button to play back the
simulation without waiting for Working Model 3D to compute every
frame.
1.10 Exporting a Video for Windows (AVI) File
Your Working Model 3D simulation is a great way for people to
visualize your ideas. To demonstrate the coin drop simulation, you can
reopen the file at a later time and play it back; however, you must assume
that the Working Model 3D application is available where you want to
show the demonstration.
Instead, you can save the simulation file in the Video for Windows
format—a common format for animation files under Windows—and
distribute the “video” file. Anyone who has a Windows PC can play back
the file. In fact, Working Model 3D simulations will play back more
quickly as Video for Windows movies.
To export the simulation as a Video for Windows file:
1.
Using the Pan, Zoom In/Out, and Rotate Around tools, arrange
the view.
The Video for Windows file will record the simulation exactly as it
appears in the Working Model 3D document window. Make sure to
“prepare the scene” before you start exporting.
2.
Choose Export Video in the File menu.
The Export Video dialog appears (Figure 1-17). Note that Working
Model 3D automatically defines the first and last frame numbers
according to the existing simulation history.
