The shader is the problem, not the solution. ;) The besy way to handle
this is knowing in which volume the particles can be. Then you can set
the bounding volume of the Node that contains them to that volume and
make it static:
// set volume static to prevent constant update
beginEditCP(pnode, Node::VolumeFieldMask);
Volume &v=pnode->getVolume(false).getInstance();
v.setEmpty();
v.extendBy(Pnt3f(0,0,0));
v.extendBy(Pnt3f(1,1,1));
v.setStatic();
((DynamicVolume&)pnode->getVolume()).instanceChanged();
endEditCP (pnode, Node::VolumeFieldMask);
What is actually the difference between pnode->getVolume() and
pnode->getVolume(false) ? From the docs it seems they're equal, since
Node::getVolume(bool update) is almost the same as Node::getVolume(void),
and certainly seems to be the same when update is set to false.
Also, why do you need to call DynamicVolume::instanceChanged() ? This
doesn't seem to be very intuitive (and also Gerrit's similar example seems
to omit this) plus e.g. DynamicVolume::extendBy() seems to call it
anyway...
Just being curious,
Akos
