In response to Matt’s post <http://blog.enzotools.org/yt-development-healpix- and-contour-tree> on the HEALpix rendering update, I thought it would be worth posting an example movie. This shows the all-sky rendering of an observer moving from the front face of a simulation through the volume to the back face. The test simulation is 32 Mpc/h on a side with 64^3 root grid cells and up to 4 levels of refinement. At the start it looks like a disc because the entire simulation is in front of the camera and by the end it is all around the sides, indicating the simulation is behind the camera. Enjoy!
