SiG Software Integration GmbHHi all,

simple question: how can I add objects, e.g. simple spheres, to a life
graph?

Background is: I like to dynamically add 3d-datapoints read from a external
data feeding device each minute to even the same transformation group.
Depending on the users choice on the limit the oldest data points should
disappear then, while he still is able to rotate, translate an zoom it
manually.

I have already learned from a posting of Nathalie (Nov 8, 2000), that I have
to set for "each Group node in which I want to add or modify children I must
set the capabilities ALLOW_CHILDREN_READ, ALLOW_CHILDREN_WRITE and/or
ALLOW_CHILDREN_EXTEND.

Adding a new node results in the error message "only a BranchGroup node may
be added".

Does it mean, that I have to reconstruct my BranchGroup and compile it every
time (every minute in my case) for all that hundreds or (depending on the
users choice) thousands of data points?

If so - is there now workaround? Are there no "not so obvious features"
hidden somewhere in the deep j3d-structure, which could enable a more
flexible near life behaviour?

I would be thankful for any hints, comments and of course a MiRCE (minimal
running code example).

thanks

Horst
