This is the first official release of Py-SPHViewer. This is a publicly available Python package to visualize and explore N-Body + Hydrodynamical simulations. In particular, it was developed to visualize cosmological simulations, but it can be applied to render any set of particles. The Smoothed Particle Hydrodynamics interpolation scheme is used to interpolate the underlying density field (or any other property) traced by a finite set of particles, thus producing smooth images of a particle distribution that can be easily interpreted. The computation of the images is made fully in parallel using OpenMP, and its is almost straightforward to extend its use within distribute memory systems using mpi4py.
