I want to animate the motion of the nozzle of a rocket using matlab. it would be basically a gimballing motion.
the problem has 2 parts
1) an animation from the back-view of the nozzle.
Think like this ...if i have a pen(laser light) along the axis of the nozzle with tip pointing towards the exit...now i put circular cardboard to cover the end....then the pen will make a dot at the cardboard at any point of time....now on gimballing (moving the nozzle) a plot will be formed....so i have to show that plotting. I can make a polar plot...but successively (something like a COMET in matlab)how to show the movement of that point on the card board.....do we anything like comet(polar) or polarcomet????
2) have to animate the conical motion of a rocket....so that it moves in yaw, roll and pitch plane all at the same time...

I have the table of movement in t,x,y so that at any time t i can get the coordinates of the point as x,y

Help needed ASAP !!
thnx

Can you just make up a movie file? The help describes how to make avi
files, etc. You can then play the videos inside an axes.

hi
FOR FIRST PART...
suppose my file is point.dat having columns time, x axis and y axis
I tried something like this....but it is not working....


{{{
load('point.dat')
x=point(1,2);
y=point(1,3);
hold on;
h=polar(cart2pol(x,y),'g.');
set(h,'erasemode','none');
grid on;
for i=2:length(point)
[x y]=cart2pol(point(i,2),point(i,3));
set(h,XData,x,YData,y);
end
}}}

FOR PART TWO I GOT NO CLUE>>>>IS IT EVEN POSSIBLE WITH MATLAB>>>OR WILL HAVE TO USE SOME ANIMATION SOFTWARE LIKE MAYA-3D OR SOMETHING

Thanx for responding....
