NAME
       3dpong -	three dimensional Pong clone

SYNOPSIS
       3dpong display1 [display2|--computer] [--gravity	g] [--net n] [--sound]
       [--noclick1] [--noclick2]

DESCRIPTION
       3D  Pong	is a three-dimensional clone of	the ancient computer game Pong
       for the X11 window system.

       There are three modes of	play

       one player
	      One player mode agains the computer

       two players
	      Two human	players, each with their own view at the game

       handball
	      One human	player against gravity.	 This is like throwing a  ball
	      at a wall

       The  player(s)  is  presented  a	 three	dimensional view at the	arena.
       There is	a white	divider	in the	middle,	 or  possibly  the  net.   The
       player  one's paddle is a red square, the player	two has	a blue paddle.
       The current score is displayed in the upper left	corner.	 The ball is a
       green diamond, and dark green markers follow the	ball on	the  walls  to
       display it's position in	relation to them.

       The  player(s)  controls	 a  paddle  at one end of the arena with mouse
       movement.  To serve, the	player presses the mouse  button  three.   The
       key  c  toggles	whether	 the player needs to keep the mouse button one
       pressed while dragging the mouse.  See also the --noclickn switches be-
       low.

       Six views exist,	switched amongst with the key v

       normal 1st person perspective from behind the paddle

       bleacher
	      Side view, with the paddle on the	left

       above  From above, paddle on the	top

       freeview
	      Any angle	the user selects, by pressing  mouse  button  two  and
	      dragging the mouse

       follow the ball
	      The view follows the ball

       follow the paddle
	      The view follows the paddle

       Key  3  toggles	red/blue  mode to be used with appropriate 3D glasses,
       with red	for the	left eye.

       The game	quits if the q key is pressed.

       The game	goes on	until quitted.	In the one or  two  player  games  the
       ball  gets  faster  and	faster until someone scores.  Players score by
       getting the ball	behind the opponents paddle.  In the handball mode the
       player scores every time	the ball bounces off the paddle, and does  not
       go to the goal.	The high score will kept for the session.

OPTIONS
       The  switches  display1 and display2  specify  the X11 displays for the
       game.  The first	is mandatory, and ``$DISPLAY'' is often	a  good	 value
       for  it.	  The  special	value  ``computer''  means that	only one human
       player is to play, the other will be a computer player.	 If  only  one
       display is specified, then a handball game is started.

       Attention to the	order of the options must be payed.

       --gravity g
	      The gravity to use.  In one and two player games,	this is	toward
	      the floor, and in	the handball it	is toward the paddle.  Minimum
	      gravity  for  handball  game is 0.1, and negative	values are not
	      allowed, unlike in the other  two	 modes.	  A  synonym  for  the
	      switch is	-g g

       --net n
	      To  use  a  net in the one or two	player modes, use this switch.
	      The value	of n must be 0>n>0.75.	The net	will be	in the middle,
	      between the two players and when	the  ball  hits	 it,  it  will
	      bounce  back  at	full  force.  The maximum height, 0.75,	is two
	      thirds of	the height of the game	arena.	 A  synonym  for  this
	      switch is	-n n The net option must not appear before the gravity
	      option.

       --sound
	      To  use  sound  in the game, use this switch or it's synonym -s.
	      This must	appear after the optional net switch.

       The switches --noclick1 and--noclick2 mean that	the  specified	player
       need  not  to  keep the mouse button 1 pressed down.  Such options must
       appear last on the command line.	 The key c can also be used to	toggle
       this while the game is running.
