Hi guys,
sorry about the _very_ offtopic post, but since there are some people here
who know Performer a lot better than me, I thought I'd ask anyway. :-)
I'd like to test the tessellation performance of Performer (no pun
intended :) vs. OpenInventor and OpenSG. Since we have most of our models
in .iv format I tried to load .iv files containing higher order geometry
(basically NURBS :) into Perfomer using pfconv and perfly. However, it
seemed that the .iv loader built into Performer (and thus implicitely used
by both apps) uses OpenInventor to tessellate everything down to
primitives and only the primitives (in this case triangles) end up in the
Performer scene-graph. A quick look into the supplied source of
``/usr/share/Performer/src/lib/libpfdb/libpfiv/pfiv.C'' seems to confirm
this, pfIv uses the OpenInventor-provided callbacks to extract primitives
from the scenegraph and uses these to build the Performer-graph.
It seems that the only option to do what I want is to write my own
Inventor-importer which passes the higher order geometries to Performer's
tessellators, which seems a bit like reinventing the wheel once again.
Therefore my question is, does anyone happen to have such a tool that they
could share with me? Or do I really have to resort to writing such an
importer myself...
Thanks in advance and sorry again for the offtopic post,
Akos
