Making Movies

Making A Movie This week you will learn how to make a simple QuickTime movie using computer animation. You can use SilverHammer to make movies and model dynamic processes in electromagnetics. 1. Overview: Hardware: 1. Making movies uses a lot of memory. A basic system will require about 5 MB minimum. 12 MB is better. 2. SilverHammer requires a Mac with a floating point processor. Software: The required software tools are (these are already installed in the computers in 86 Hutchison: 1. QuickTime requires System 6 or System 7. 2. The QuickTime init installed in your extensions folder which is inside the system folder in System 7, or just place the init in the System Folder if you are running system 6. 3. The SilverHammer program to produce the frames. 4. The "Movie Converter" program to compile the frames into a movie. Process Outline This is just an outline of major steps in the process. A detailed description is provided in the next section. : 1. Set up your computer. 2. Generate the frames using SilverHammer. 3. Copy frames in reverse order to the Scrapbook (start with the last frame first). 4. Compile your movie using "Movie Converter" 5. Copy your movie to your floppy disk. 2. Movie Making 1. Machine Setup: Make sure you have quit all other programs and desk accessories. You can check under System 7 by holding the mouse down when the cursor is over the rightmost icon in the Menubar. This will provide a list of running programs. Open the System folder and drag the "Scrapbook File" to the trash. This will cause the Scrapbook desk accessory to start a clean fresh file for your pics. 2. Frame Generation: Enter charges in the Charges window. Assign each charge a velocity by clicking on the velocity tool and then dragging an arrow from the center of the charge to the length you wish. If you exceed the speed of light., the program will warn you. Draw a smaller arrow. Put in two or three charges with velocity. After you have your charges entered, go to the Graphs window. From the Fields menu choose "Use Magnetic Fields". Draw a graph using the color fill density plot. When the graph has drawn, advance the time bar in the Charges window and draw another graph the same size as the first graph. To do this place the cursor on the top left corner of the previous graph and drag to the lower right corner. Continue this process of advancing the time in equal increments and drawing graphs until you have six graphs. 3. Copy Frames to Scrapbook in Inverse Order: Select the last graph drawn (largest time) and choose copy from the Edit menu or type Command-c. (To select a graph, click on it. The program will place small squares called "handles" on the outside of the object. The command key has the funny four-lobed symbol and is next to the spacebar.) Next go to the Apple Menu and choose "Scrapbook". When the Scrapbook opens…
