It is being made available during an extensive Meats and Muscle Biology Section Project to investigate the time involved in cutting beef wholesale cuts into steaks and roasts, therefore a larger amount of freshly cut retail cuts are generated. The fresh cuts will be available on the following dates: Sept. 27 and 28 Oct. 25,26, and 27 Oct. 11 and 12 Nov. 1 and 2 Nov. 8 and 9 Please stop by and shop with us. The Rosenthal Meat Science and Technology Center is open Monday through on home football Saturdays from 9:00 am till Friday 9:00 am till 6:00 pm, and open on 1:00 pm.

Percifield Jr. stands next to his great uncle’s old boots, which were once lamps. Class of ’38 boots return to Texas A&M once again By ISSELLE MCALLISTER Of The Battalion Staff Many people snub hand-me- downs, but not John M. Percifield Jr. The senior Aggie Band bass cap tain and repair officer from Alva rado is proud of the senior boots that have been in his family for more than half a century. The boots were made in 193 7 for his great uncle John O. McLeroy Jr., Class of’38. His father, John Percifield Sr., Class of ’63 and also a former Aggie Band bass player, used them next because he could not afford a new pair. Since the boots are custom made, the elder Percifield had to have them enlarged to fit his bigger calves. By this time, the boots had be come a family tradition. McLeroy’s twin sons, John Ronald and William Donald, both Class of ’68, were too short to wear the boots and continue the legacy, so they had them made into lamps as gifts for their predecessors. John Percifield says the sons gave the right boot to McLeroy and the left boot to his father. The lamp, which looked like a se nior boot with a lampshade on top, decorated John’s room for more than 15 years. He says he didn’t real ize its significance until he was in high school. “I thought it would be pretty neat to wear these boots again,” he says. He asked his father and great un cle if he could have them, and to his surprise he received ihem as Christmas gift. As an underclassman, John dertook the ominous task of bishing the boots, which hadn'tbee maintained for more than 20 yeas he says. He was forced to keep hispriis boots a secret for fear of being pat ished by senior cadets for havingb boots in his possession as an untfa classman. Today the boots look like new. Because of their age and John says he wears his “hand-w down” boots only on special oco sions. “They’re so old,” he says, something happened to them hate to have to explain to my I iy” Air Force funds grad student’s study of 3-D computer simulated imagery By BILL HETHCOCK Of The Battalion Staff When most people think of 3-D, they think about funny-looking glasses and objects jumping off a movie screen in a crowded theater. But in one Texas A&M graduate student’s office, 3-D objects are jumping off a computer screen. John Williamson, a psychology graduate student, is researching ways to harness three-dimensional technology for uses outside the cin ema. The Air Force is funding his com puter imagery study to determine whether its computer simulations are realistic and cost-effective. “What I’m primarily interested in is how to accurately portray 3-D onto the screen, and does it justify the fi nal cost,” Williamson says. It takes a special monitor, a ste reoscopic graphics adapter and po larizing glasses worn by the user to perceive three-dimensional com puter graphics. The adapter sends two slightly different views of the same image to the monitor. These images are pro jected onto two separate planes on the screen. The glasses decode the polarized images to provide the left and right eye views, which create the three-di mensional look, Williamson says. “Each eye sees a slightly different image of the world, and these two images are merged in the brain,” Williamson says. “That’s what allows us to see the world in three dimen sions.” The problem with three-dimen sional imagery is its high cost, Wil liamson says. The monitor, adapter and glasses cost about $9,000 plus the cost of the computer that runs the application, he says. The Air Force uses three-dimen sional computer imagery to prepare pilots and air traffic controllers for situations requiring depth percep tion. It gave Williamson a $20,000 grant to find out if improving the realism of computer simulations would be cost-effective. Williamson is trying to find out if less expensive computer simulations will work as well as the 3-D genera tions. To do this, he uses geometric con figurations. A pair of outline draw ings is generated onto the screen different angles. Subjects are asked to ii whether the two configurations ‘ identical, or if the shapes are min* images of each other. This is done by “mentally $ ting” the configurations, Williams says. “We form an image in our and mentally rotate it, just like ii* physical object,” he says. Williamson measures the dm f takes people to make these me* 1 ; rotations and determine if shapes are identical.
