Hi Carsten,

The pfNode class is an abstract class which has at least one pure virtual
function and is used in Performer as a the base class for the node type classes
(pfGroup, pfSCS, ...). No object can be created from an abstract class until
all its pure virtual functions are defined.

An easy way to get around this problem is to derive new classes from pfGroup
which has no pure virtual function.

There you go !

Have fun,

Jean-Luc
