Complicated growable array

[breakerbyte]

Hi codeguru users!

I am basically looking to make a growable array thats basically as follows:


{ [ ((PT1.X,PT1.Y,PT2.X,PT3.X),(PT1.X,PT1.Y,PT2.X,PT3.X),(PT1.X,PT1.Y,PT2.X,PT3.X) )] }

the arrays size grows a lot.
(pt1.x/y are points i am using via opencv)
the larger picture ie the outside "()" represent an object
the second set of "()" represent the iterations
and the individual elements of the iterations (the points) are points

if you help me i will love you forever

EDIT: the array increases by each of the above (marked with "[]")
