Abstract
ParaView and VisIt play a key role in the visual understanding of scientific simulation data. These tools are open source, designed to handle extremely large datasets, and can run on supercomputers and large-scale display walls. They are in daily use by scientists, practitioners, and students at supercomputing centers, in industry, and at universities. This article gives personal accounts of the origins of these visualization tools.

We were all still feeling some of the sting of the missed connections and what could have been when a new revolution hit HPC at the turn of the next decade. As the features of graphics cards grew, their GPUs became more general purpose. Suddenly, GPUs went from being available on nearly no cluster computers to being on the most powerful supercomputers, which, ironically, were still ill suited for rendering. The change did not go unnoticed to the scientific visualization community, and multiple research projects started to update our visualization software to this new generation of computers. Ahrens managed PISTON, a project funded under ASC, Moreland led Dax, a project under the DOE Office of Science Advanced Scientific Computing Research (ASCR) program, and a third project, extreme-scale analysis and visualization library (EAVL), was funded by DOE laboratory directed research and development at Oak Ridge National Laboratory.11 As these projects began to produce viable software, it became clear that these software libraries would soon vie for adoption.
