#5367 — patroling space recipe

I am lurking long time to do that

probably it is not so hard to do 
also is not so easy

you got small starship (say 10 meters 
long) you also need some small cosmic 
station or 'buoy' in space

the ship has to fly around the buoy
(not sure how far probably about 500
meters, and waste a time - but in general 
its movement should look nice, 

It could probably slowdown and 
acclelerate and move gracefully

I need a recipe for this movement when basic
operations you have is 

MoveForvard(float distance)
StrafeRight(float distance)
StrafeUp(float distance)

MoveYaw(float distance)
MovePitch(float distance)
MoveRoll(float distance)
// (you know whats that, isnt, you)

you may asume 50 frames per
second

void MoveShip()
{
  static frame = 0;

  MoveForvard(1.0); //50 m/s forward

  //... what recipe here ?

  frame++;

} 

(fir)

You can simplify the problem considerably if you choose a frame of
reference in which the spaceship is at rest.  Then, translate or
rotate space about the spaceship in any way you like.  With this
method I am fairly sure that you will achieve framerates far in excess
of your baseline rate, and which ought to leave plenty of computer
horsepower for things like player missles and such.

A farmer has twelve workers who require three weeks to harvest the
farmer's fields.  The farmer eats four workers.  How long will it take
him to harvest his crops if all of the other independent variables
remain constant?

I need maneuvres/moves not for player ship 
but for side bots, I dont worry abut efficiency (this is cheap) i only need
it to look fine.. Need to define some fine looking movement behaviours in code that
calls to the simple 6 movements: yaw, pitch, roll, forward, right, up
