NAME

       xshowtrace - interactively show rays traced on RADIANCE image under X11

SYNOPSIS

       xshowtrace [ -s ][ -T ][ rtrace options ] octree picture

DESCRIPTION

       Xshowtrace  takes  a  RADIANCE  octree  and  a picture file and displays it on an X11 window server using
       ximage(1).  The picture should have been created from a previous rpict(1) or rvu(1) calculation using the
       given  octree.   Once the image is displayed, the user can use the 't' command of ximage to select points
       on the image to display the ray tree.  Rtrace then produces a ray tree, which xshowtrace will display (in
       red  on  a color screen).  The -s option slows the display of each ray traced to make it easier to follow
       the process.  The -T option traces rays to light sources, which are normally hidden.

BUGS

       If the pointer is moved between the time 't' is pressed and xshowtrace starts drawing rays, the rays will
       be displaced.
