[ascl:1112.011] CMBview: A Mac OS X program for viewing HEALPix-format sky map data on a sphere

CMBview is a viewer for FITS files containing HEALPix sky maps. Sky maps are projected onto a 3d sphere which can be rotated and zoomed interactively with the mouse. Features include:

  • rendering of the field of Stokes vectors
  • ray-tracing mode in which each screen pixel is projected onto the sphere for high quality rendering
  • control over sphere lighting
  • export an arbitrarily large rendered texture
  • variety of preset colormaps
