This script is a guide to demonstrating the performance differences between PowerPC and Pentium based systems. The Pentium based systems are 60Mhz versions with accelerated PCI graphics subsystems. The average system cost of the Dell is $3500. These are points that should be made before the demonstration of the perfromance begins.
Adobe PhotoShop Demonstration
Objective: The demonstration will provide some basis for performance of applications running under Windows and NATIVE Macintosh applications. The Adobe demonstration represents the computing advantage Macintosh applications have with PowerPC and the DRAM based graphics model being approximate to accelerated Windows video.
1. Once Windows is ready open the Adobe Group in the Program Manger and select Adobe Photoshop.
2. Select File | Open from the menu bar once Photoshop loads.
3. Select an image file entitled “portrait.TIF” and click on “OK”
4. In the tool palette choose the zoom icon (magnifying glass) and click on the image of the child.
5. Then expand the window by selecting the up arrow icon in the upper right hand corner of the image window.
6. Go to the Select menu and choose All
7. Move to the Filter menu and select Blur...
8. Choose Radial Blur...
9. A dialog box representing choices for Radial Blur will appear.
10. The settings for the dialog box should be:
Amount 10
Method Spin
Quality Good
11. Select OK and the procedure should complete with a rotational blur affect on the image. ( Point out the status bar at the LOWER LEFT of the image and compare with the Macintosh PowerPC status bar)
12. Exit from PhotoShop but do not save changes.
Mathematica Reader for Windows Demonstration
Objective: The Mathematica Reader demo should be positioned as a test of calculation performance ( as the animation is being rendered and then animated ) and the performance of the DRAM based graphics subsystem ( as the animation is being show ).
1. From the Program Manger select the Math Reader for Windows group.
2. Open Math Reader for Windows.
3. Select File | Open and choose “ fourplot.ma “
4. Before doing anything else, select the hightlight bar at the far right of the fourplot.ma document. NOTHING WILL WORK UNLESS YOU DO THIS FIRST!
5. Go to the Select menu and choose “Animate selected graphics”
6. The image will then begin to generate and there should be four short “jerks” as its being generated and then the four selections will move in unison.
7. Once the point has been made select the Stop icon on the control bar at the bottom of the window.
8. Exit from Math Reader for Windows but do not save changes.
