Query: A comparative evaluation of three volume rendering libraries for the
  visualization of sheared thermal convection   Oceans play a big role in the nature of our planet, about $ 70 \% $ of our
earth is covered by water. Strong currents are transporting warm water around
the world making life possible, and allowing us to harvest its power producing
energy. Yet, oceans also carry a much more deadly side. Floods and tsunamis can
easily annihilate whole cities and destroy life in seconds. The earth's climate
system is also very much linked to the currents in the ocean due to its large
coverage of the earth's surface, thus, gaining scientific insights into the
mechanisms and effects through simulations is of high importance. Deep ocean
currents can be simulated by means of wall-bounded turbulent flow simulations.
To support these very large scale numerical simulations and enable the
scientists to interpret their output, we deploy an interactive visualization
framework to study sheared thermal convection. The visualizations are based on
volume rendering of the temperature field. To address the needs of
supercomputer users with different hardware and software resources, we evaluate
different volume rendering implementations supported in the ParaView
environment: two GPU-based solutions with Kitware's native volume mapper or
NVIDIA's IndeX library, and a CPU-only Intel OSPRay-based implementation.
