Hi all,
my problem is to be able to establish if a very precise node does not
come visualized, that is in the phase of CULL turns out external
to the view-frustum.
I have thought to some possible solutions for being able to obtain
this result but many doubts have come me.
The first idea that I have thought is to define a function of predraw
in which verification if between the nodes that come designed there is
what it interests to me.
An other idea is that one to use the functions that allow to
characterize the behavior of a node es. pf[Get]NodeTravFuncs.
I do not understand however the difference between the two functions
and above all what it'sn't clear to me is in which phase (CULL/DRAW) I can
know if the node, that to me it interests, be excluded from the successive visualization.
Someone can gives me a simple example on as they come used these two functions.
Bye Lucia
