Question: maple11 use up whole memory with animate3d

with(plots); m1 := implicitplot3d(

9*x^2+4*y^2-36*z^2

, x = -2 .. 2, y = -3 .. 3, z = -1 .. 1, grid = [20, 20, 20]); n := animate3d([x, y, t], x = -2 .. 2, y = -3 .. 3, t = -1 .. 1); display({n, m1})

 

Everytime i execte the above goes in loop, used up memory increases and status bar says
evaluating and computer slows down. I had to stop the process. what am i doing wrong?
