This article summarizes the preliminary findings from a recent study of scientists in four disciplines with regard to computer-mediated communication (CMC) use and effects. Based on surveys from 333 scientists, we find that CMC use is central to both professional and research-related aspects of scientific work, and that this use differs by field. We find that e-mail use focuses on coordination activities, and its biggest effect is helping to integrate scientists into professional networks. We do not find gender differences in use, but there is some evidence that e-mail is having a differential, positive effect for women. Furthermore, CMC use is positively associated with scientific productivity and collaboration.

A solution to the hidden surface elimination problem called Beam Tracing is described. Beam tracing is related to ray tracing but uses spatial coherence within the scene, and area coherence within the image to batch computations. Beam tracing is an object space solution to the hidden surface problem.
