Real-Life Math
You are a computer animator for a motion picture company. As part of your job, you are working on the opening credit sequence of a new film. "Most of your job doesn't use much math, but lots of drawing ability," says Caroline Paul, an animator.
"But to be computer competent, you have to do some calculations, and you have to know about how the computer operates," she says. Computer animators need to know about bit depth, bitmapping, digitizing and how a computer does these tasks, but for most day-to-day activities, math is used while working with computer programs, rotating images and calculating image size.
You are working to create an elaborate sequence that will grab the audience's attention and make them aware of the producers, directors and studio, without distracting them from the images.
As you begin, you plug in a font. The size of the font is 12. When you paste it on the computer screen, you see that it's a bit too small. You want to make the font 3/4 bigger.
- What size font do you need?
- You have an idea for an image to go along with the introduction to the film, but you don't know if your boss will like it. You want to quickly run off a copy and show it to her. The image you have now is 400 dpi (400 dots per inch). If you reduce the image's dpi by 30 percent to make a quick thumbnail for your boss to look at, how many dpi will the new image have?
