Hi, ok I think I'm beginning to get my head around ssg. I've read =
through
all the documentation several times now. What I want to do is add a few
functions and some variables to an object. I've seen a few ways that =
might
make this possible and I was hoping someone could point me in the right
direction.

Write a new class that extends an entity
Write a new class that extends a leaf node
Write a new class that extends a branch node (don't think it's this one)
Using function call backs on standard versions of the above that call my =
new
functions
Store my variables in the standard versions using the user data section

The docs say:
"It is presumed that applications will add new kinds of leaves, =
branches,
states and textures to customise SSG to their needs."

You see this is where I get confused. Leaves sound like the best choice =
to
add the extra functionality to each node, so I thought I should make a =
new
class based on ssgLeaf. But then I read up on adding user data. I
understand I can pump lots of my own variables into this and that along =
with
pre/post draw call backs I can also call my own functions on an entity =
that
uses these variables. The problem I see with extending leaves is that =
in my
demo program I don't actually specify "create a leaf of this type". I =
just
create an ssgRoot and add some ssgEntities to it. I'm using ssgLoad3ds =
to
generate the model data for each entity so I'm not sure if this creates =
the
leaves internally.

Thank you now and I'll say thank you later
