[Plib-users] ssgRoot node

[Christopher S H. <chr...@cl...>]

I've been taking a look at the flightgear source code.

I have a question to ask regarding the use of ssgBranch and ssgRoot


Reading the plib docs and looking at the examples for plib 1.6 I'm under
the impression that the scenegraph should all stem from the root node.
and there should only be one root node.

Is this assumption correct?

I ask this because flightgear would appear to have more than one ssgRoot
node.  I don't think flightgear uses ssg to manage the very top of the
scenegraph tree though - it appears to plug (for want of a better term)
these root nodes into 'something else'.

Does ssgRoot do anything automatically which would mean it would make
sense to use it for a 'module' of a project.
