Exploring this Job
If you are interested in a career in graphics programming, you might want to check out Computer Graphics World (http://www.cgw.com). In addition, you should start exploring the Internet for information about computer-related careers. One excellent resource is https://www.computer.org/communities/student-activities/career.
Contact the computer science department of a local university to get more information about the field. It may be possible to speak with a faculty member whose specialty is computer graphics or to sit in on a computer graphics class. Find out if there are any computer manufacturers or software firms in your area. By contacting their public relations departments, you might be able to speak with someone who works with or designs computer graphics systems and learn how one works.
If you are interested in the artistic applications of graphics, get involved with artistic projects at school, like theater set design, poster and banner design for extracurricular activities, or yearbook or literary magazine design. Many schools have Web sites or online versions of their newspaper or literary journal. See if you can help create graphics for these publications.
Try your hand at programming by creating your own applications, such as simple games and utility programs. Visit Codeacademy (https://www.codecademy.com), edX (https://www.edx.org), Coursera (https://www.coursera.org), and Khan Academy (https://www.khanacademy.org), where you can learn how to code for free.
Many diverse industries use computer graphics. In medicine, for example, physicians, nurses, and technicians can use computer graphics to view the internal organs of patients. Scanners feed vital information about a patient's body to a computer that interprets the input and displays a graphic representation of the patient's internal conditions. Computer graphics are used in flight simulators by airlines and NASA to train pilots and astronauts. Weather forecasters and television newscasters use graphics to explain statistical information, such as weather or stock market reports. Business people use computer-generated graphs and charts to make their reports more interesting and informative. Engineers use computer graphics to test the wear and stress of building materials and machine parts. The movie industry has found ingenious ways to use computer graphics for special effects. Professional artists have explored computer graphics for creating works of art.
The graphics programmer's job is similar to that of other computer programmers: determining what the computer will be expected to do and writing instructions for the computer that will allow it to carry out these functions. For a computer to perform any operation at all, detailed instructions must be written into its memory in a computer language, such as BASIC, COBOL, Pascal, C++, HTML, Smalltalk, Java, and Python. The programmer is responsible for telling the computer exactly what to do.
A graphics programmer's job can be illustrated by tracing how a program designed for desktop publishing is developed. Working with a computer systems analyst, the graphics programmer's first step is to interview managers or clients to determine the kinds of tasks the program will be expected to perform, such as drawing shapes, organizing text, and adding different colors. The programmer investigates current computer graphics capabilities and how to improve them.
Once the program is written, it is tested thoroughly by programmers, digital designers, and quality assurance testers to make sure it can do the desired tasks. If problems, or glitches, do exist, the program must be altered and retested until it produces correct results. This is known as debugging the program.
Once the program is ready to be put into operation, the programmer prepares the written instructions for the people who will use the graphics program in their daily work.
Graphics programmers can be employed either by software manufacturing companies or by the companies that buy and use the software (known as the end user). The programmer who works for a software manufacturer will work on programs designed to fit the needs of prospective customers. For example, the programmer might work on a report-writing program for businesses, and so develop simple ways for people to display and print statistical data in the form of diagrams, pie charts, and bar graphs. Programmers, working alone or as part of a team, must make the product user friendly.
Graphics programmers who work for end users have to tailor commercial software to fit their company's individual needs. If a company has limited computer needs or cannot afford to keep a programmer on payroll, it can call an independent consulting firm that has graphics programmers on staff and hire consultants for specific projects.
