NAME
       qray - Gets/sets	query ray characteristics.

SYNOPSIS
       qray [subcommand]

DESCRIPTION
       Gets/sets query ray characteristics. Without a subcommand, the usage
       message is printed. The qray command accepts the	following subcommands:

       vars
	   Prints a list of all	query ray variables.

       basename	[str]
	   If str is specified,	then set basename to str. Otherwise, return
	   the basename. Note that the basename	is the name used to create the
	   fake	shape names corresponding to the query ray. There will be one
	   fake	shape for every	color used along the ray.

       effects[t|g|b]
	   Set or get the type of effects that will occur when firing a	query
	   ray.	The effects of firing a	ray can	be either t for	textual
	   output, g for graphical output, or b	for both textual and
	   graphical.

       echo [0|1]
	   Sets	or gets	the value of echo. If set to 1,	the actual nirt
	   command used	will be	echoed to the screen.

       oddcolor	[r g b]
	   Sets	or gets	the color of odd partitions.

       evencolor [r g b]
	   Sets	or gets	the color of even partitions.

       voidcolor [r g b]
	   Sets	or gets	the color of areas where the ray passes	through
	   nothing.

       overlapcolor [r g b]
	   Sets	or gets	the color of areas that	overlap.

       fmt [r|h|p|f|m|o	[str]]
	   Sets	or gets	the format string(s). See the man page of nirt for
	   more	details.

       script [str]
	   Sets	or gets	the nirt script	string.

       help
	   Prints the usage message.

EXAMPLES
       The four	examples show the use of the qray command without a subcommand
       and with	three of the listed subcommands.

       Example 1. Print	the usage message.

       mged>qray

       Prints the usage	message.

       Example 2. Return the overlap format string.

       mged>qray fmt o

       Returns the overlap format string.

       Example 3. Return the rgb color used to color odd partitions.

       mged>qray oddcolor

       Returns the rgb color used to color odd partitions.

       Example 4. Set the odd partition	color to red.

       mged>qray oddcolor 255 0	0
