pfPeople->hello()

so imagine I am trying to turn nodes on and off. (actually it is a
light, but that is a node)

I am going to use
pfLightSource* _light = new pfLightSource;

_light->setTravMask(PFTRAV_CULL,?????,PF_SET);

I don't know what goes in ????????

0x0 for off
and
0xf for on

Is that right that I don't put a setMode arguement in the function call
if it isn't a ISECT traversal?

How exactly are these masks intended to be used? The book gives a short
explanation on ISECT masks but doesn't really go into why you should use
a mask as opposed to a callback.

Thanks

PS- has anyone else had problems with useing new for objects like
pfVec4??? It doesn't seem to agree with the documentation, if I don't
specify a memory area.....

pfVec3* larry = new pfVec3;

larry seems to be local (non shared) memory. If I use pfMalloc
(getSharedArena()) all the problems go away..... This is _NOT_ how the
man pages describe it working.
