You have a position of the laser at t=0, and you know which way your ship's
facing.
All you have to do is to calculate a k vector with the speed of the beam and
add that
to the laserbeams position every frame. At least that's how I would do it :)

vector k, ship_pos(0, 0, 0), beam_pos(0, 1, 1), ship_angle(60, 0, 10); //
for example
vector beam_speed(0, 0, speed); // for example
k=beam_speed.rotate(ship_angle.x, ship_angle.y, ship_angle.z);
then for every frame do:
beam_pos+=k;
that should do it, now I haven't tested this since I don't have the
compiler.. I really need the compiler guys!!!.. haven't gotten any response
from sony. Could anyone mail me the compiler?? please.. ah well, I don't
know.
