NAME
     makeIBRimages - OpenGL Performer tool for generating images for image-
     based rendering

SYNOPSIS
     makeIBRimages infile1 [ options ]

DESCRIPTION
     Program makeIBRimages is one of the tool programs distributed with the
     OpenGL Performer high-performance graphics library.  Its source is
     located in /usr/share/Performer/src/conv/.  It can be used to create
     images (views) of the specified object from a set of directions.  The
     input is a file that can be read by OpenGL Performer and the output is a
     set of images of that object that can be directly used as an input for a
     pfIBRtexture.  The images are stored in a directory specified using the
     option -f.

     If a text file 'info' is present in the output directory a set of 3D
     views is rendered. The file has the same syntax as described above.  Each
     line of the info file contains two values: the angle from the horizontal
     plane and how many views are created for that angle. The images are then
     indexed by two integer values that are appended to the name specified by
     the option -f. The first value is the index of the ring of views and the
     second one indexes the views within the ring.

     If the info file is not present a set of N views (set by the option -n)
     is computed around the object using horizontal angle of 0.  In this case
     only one index is appended to the image name.

     If option -pfb is specified the program outputs a pfb file in the
     specified directory. The file contains a single pfIBRnode that uses the
     created images. Note: before loading in perfly make sure that PFPATH is
     set to the directory with all images.

     To obtain the full set of command line options run the program
     makeIBRimages without any parameters.



NOTES
     If your machine does not support a single-buffered visual with at least 8
     bits per red, green, blue, and alpha component the images may be missing
     alpha channel. See the number of alpha bits printed at the beginning of
     the makeIBRimages.
