  The growth of computational astrophysics and complexity of multidimensional
datasets evidences the need for new versatile visualization tools for both
analysis and presentation of the data. In this work we show how to use the open
source software Blender as a 3D visualization tool to study and visualize
numerical simulation results, focusing on astrophysical hydrodynamic
experiments. With a datacube as input, the software can generate a volume
rendering of the 3D data, show the evolution of a simulation in time, and do a
fly-around camera animation to highlight the points of interest. We explain the
process to import simulation outputs into Blender using the Voxel Data format,
and how to set up a visualization scene in the software interface. This method
allows scientists to perform a complementary visual analysis of their data, and
display their results in an appealing way, both for outreach and science
presentations.
