We test a lot of things here at JPR and at JPA before that. We’ve been testing stuff officially and unofficially for 30 some years—you’d think we’d know what we’re doing. Hell, we thought we knew what we were doing. This last batch of graphics AIBs really threw us. We couldn’t get things to work. Benchmarks wouldn’t bench. Command lines needed to set parameters wouldn’t work. Resolutions would stay stuck, and over-clocking tools defied us to make them behave—and all the while the clock is ticking …. No one wants to read about a test done on a product that was…

Been seeing double for a very long time

The idea of using a computer for stereovision representation of molecules dates back to Project MAC at MIT in 1966. And in the early 1980s the concept became known “molecular graphics” and the Molecular Graphics Society (MGS) in the UK formalized the notion and science of computer-based molecular modeling. Initially much of the technology concentrated either on high-performance 3D graphics, including interactive rotation or 3D rendering of atoms as spheres (sometimes with radiosity). The first stereovision machine I saw was an Evans & Sutherland (E&S) workstation in the early eighties. It had a vector (“stroke”) display. The stereo device or selection…
