SkyViewer is an OpenGL based program to display HEALPix-based skymaps, saved in FITS format files.
The loaded skymaps can be viewed either on a 3D sphere or as a Mollweide projection. In either case, realtime panning and zooming are supported, along with rotations for the 3D sphere view, assuming you have a strong enough graphics card.
This is free and open source software.
Key Features
- Real time rotation, zooming, and panning of map.
- Choice of 3D sphere or 2D Mollweide display.
- Pixel texture aligns with HEALPix pixel boundaries.
- Select pixel and get information for the pixel.
- Adjustable mapping from pixel value to color.
- View Temperature, Polarization or Nobs fields.
- View polarization direction vectors.
- Save screen shots to image file.
- Contextual help.
- Cross-platform support – runs under Linux, macOS, and Windows.
