Viewer of hdr/pfm images

fv is an HDRI viewer. Currently supported formats are the followings

  • Greg Ward’s HDR also known as Radiance/PIC/RGBE. See http//www.graphics.cornell.edu/~bjw/rgbe.html for details.
  • Paul Debevec’s PFM Portable Float Map. See http//netpbm.sourceforge.net/doc/pfm.html for details.

fv reads data from the standard input or files specified as arguments. In the latter case, each file may be compressed one with gzip or bzip2. The file may also change after fv is invoked, except its header part. fv checks whether the file changes and updates the display if necessary. This feature is useful for checking intermediate outputs from renderers.
