Hi Sakis,
The basic idea is that in order to do this kind of thing you need
to create a pfGeoArray which has an attribute of type
PFGA_GENERIC_ARRAY.
The man page for pfVertexAttr along with pfGeoArray should be
enough to point you in the right direction but you can also take a
glance at %PFROOT%/src/sample/pguide/libpf/C++/multiTexShader.cxx and
gprogram.cxx (/usr/share/Performer/src/sample/pguide/libpf/C++/
multiTexShader.C and gprogram.C on IRIX & Linux) to help with this.
These examples aren't exactly what you're looking for but ...
hopefully it will be enough to get you started. Feel free to post
again if you need more help; I know our samples for doing this aren't
quite "good enough".
Hope this helps,
Alex.
