[Plib-users] ssg pyysics

[Simon <sim...@ho...>]

Hi, thanks Wolfram its great to get a reply although I don't think I
explained myself very well.  The aim I'm trying to reach is to have a =
stack
of blocks on top of each other.  I then want to knock them down.  I =
found
this great physics example to do with dice falling down some stairs.   I =
can
get it to work with a non plib scene but I was trying to link it to an =
ssg
tree.   What I really want to know is how everyone goes about that. =20

In the non plib demo each object maintains a set of physics related
properties.  There is also a physics class that each inherits from.
Basically the physics engine runs constantly and checks then updates =
each
object in relation to each other object.  I think in just writing this I =
am
beginning to work the answer out myself.  Isnt it funny how sometimes =
just
writing or saying something out loud can make things so much clearer.

So now I guess the question is should the physics engine class be added =
to
the tree or left to run outside of it?  It's a little difficult for me =
to
recall everything as the project has been on hold until this bit gets =
worked
out.  For anyone interested; the demo that I'm basing this on for now is
from Chris Haag.  I got it off his site originally but that seems to be =
down
at the moment.  Theres a copy of it on the NeHe site:

It's called Stairs by Chris Haag.

Thanks for the patience, if I get it to work then I could submit it as =
an
ssg example.  I'm using the 3D Studio loader for the dice and the stairs =
so
the example would incorporate that as well.
