Doctors are eager to go ahead with multidrug experiments and more extensive tests of existing drugs. "It's terrible going into room upon room of patients who ask what we can do, and to have to tell them we have nothing to offer," says Dr. Donald Abrams, assistant director of the AIDS clinic at San Francisco General Hospital. One major obstacle, researchers agree, is a lack of federal funds. "The Administration is giving lip service to this disease but not the funding," complains Immunologist Allan Goldstein of George Washington University. Federal allocations for AIDS research have risen steadily from...
Today's most advanced graphics systems take Evans and Sutherland's procedure one step further. Using a programming technique known as ray tracing, they follow the path of each ray of light as it travels from its source, say the sun, to the viewer's eye. Upon striking a surface, each ray will be absorbed, reflected or transmitted in accordance with the laws of optics. Programmed with a mathematical model of the behavior of light rays, the machines can re-create lighting effects of dizzying complexity. Caltech's Jim Kajiya, for example, has used ray tracing to show how ripples...
Last week's SIGGRAPH attendees got a taste of that insight during a 3-min. film sequence, produced at Lawrence Livermore Labs, that showed in a few seconds what biology teachers have labored for years to make clear: the precise mechanism by which molecules of DNA fold upon themselves to form thick strands of chromosomes. "It's something you could never do with a camera," says Livermore's Nelson Max. The audience at SIGGRAPH greeted his technological tour de force with enthusiastic applause...
...Upon the release last spring of the 67-page Summary of Principal Recommendations for the Review, professors attacked the report for want of focus and vision, in spite of the report’s many specific suggestions for curricular reform...
