NAME
     blast - 3D space war game

SYNOPSIS
     blast [-T] [-t time] [-a]

DESCRIPTION
     blast is an interactive 3D game where the user destroys asteroids to gain
     points. There are several large asteroids in orbit around a small proto-
     planet.  From your space station base, you must venture out and shoot
     these asteroids to break them into smaller pieces without colliding into
     either the asteroids or the proto-planet.  Watch out for the alien ship
     that fires back at you!  Destroy this ship before it destroys you. (All
     divestments, embargoes, blockades, economic sanctions, and other politi-
     cal actions have failed with the 'aliens')


OPTIONS
     -T is for no texture mapping

     -t <time>  is for duration of play.  <time> is in integer units of view
     updates.  2000 is about a minute depending on frame rates.

     -a is for audio (currently only for vigra board)


CONTROLS
          The leftmouse button fires your rockets to move forward.

          On a PI or INDIGO: The middlemouse button enables the rocket to move
     in a roll/pitch motion instead of the default yaw/pitch.

          On a PowerVision or RealityEngine: the middlemouse button fires an
     asteroid seeking missile

          The rightmouse button fires normal missiles


          The X position of the mouse controls your yaw

          The Y position of the mouse controls your pitch

          The space bar will show a set of 3D lines that point toward as-
     teroids.  Green lines point to asteroids in front of you, blue lines
     point behind.


          There are inertial dampeners that will eventually slow you down if
     you do not fire your rocket thrusters.
SCORE
          BIG asteroids:         20 pts
          MEDIUM asteroids:      50 pts
          SMALL asteroids:      100 pts
          alien ship:          200 pts

          The score is shown as a large red LED display
          your speed is shown as a small yellow LED display
          time left is shown as a small green LED display

NOTES
             It takes a lot of practice to be able to judge the proper amount
     to lead an object when firing at it.  This makes hitting an asteroid
     rather tricky for the novice.  Note that asteroid size, speed, direction
     of travel, and distance all have to be taken into account.   The easiest
     way for a beginner to actually hit an asteroid is to fly up close to it.

             The yaw and pitch controls are a little bit like those in an air-
     plane.  pulling the mouse towards you makes you pitch up, just as pulling
     an airplane stick towards you makes the plane pitch up

             asteroids that fall onto the proto-plane self destruct on impact

             After the number of remaining asteroids is diminished, a new set
             of asteroids appear.

             After 3 lives are used up, game prompts user for a reset
