Thanks for the response. However, to construct a geometry array, one of
the parameters that must be passed is the vertex count, which is simply an
integer. If you pass 0 as the vertex count, then I have not been able to
later increase this vertex count which has been the problem here. Any
ideas to address that would be great...
Thanks,
Nick

Hi Nick,
Not sure if this is what you're looking for, but in cases I don't know the
size of the array beforehand, I do the following:
At initialization (so, before the first constructor) I declare:
float cords[];
And inside the constructor, just before the GeometryArray, when the number
of vertices are known, I state:
cords=new float[whatever number];
Again, not sure if this will help you, but it works for me.
Have fun, Dirk
