NAME
       pixhist3d - display RGB color space utilization

SYNOPSIS
       pixhist3d [file.pix]

DESCRIPTION
       pixhist3d builds	up a count of color frequencies	in the RGB color space
       and then	displays three orthographic views of this color	space. An RGB
       color cube with red, green, and blue values from	0 to 255 form a	right
       handed coordinate system. Three faces of	this cube are displayed	where
       the intensity of	the pixels shown for each face correspond to the
       integrated frequencies through the color	cube perpendicular to that
       face. These frequencies are scaled so that the maximum value is full
       white, and any non-zero scaled count less than 30 is displayed at
       intensity 30 so as to be	visible.

       The faces are:

       Lower left: red vertical, green horizontal

       Upper left: blue	vertical, green	horizontal

       Lower right: red	vertical, blue horizontal

       The environment variable	FB_FILE	is used	to select the display device
       (see brlcad(1)).	If this	variable is not	set, the default device	for
       your system will	be used.
