I already send this question but had no response.
Any information or help on this will be very very appreciate.
Loading the same scene in our software using multiprocessing
APPCULL_DRAW and APP_CULL_DRAW, the resulting display is the
same in both case but the draw is slower in APP_CULL_DRAW than
in APPCULL_DRAW on an onyx InfiniteReality2.
Statistics show differences concerning the visible nodes.
Culling statistics are the same in both case. But at draw time,
the DCS are NOT considered visible in APPCULL_DRAW. Althought
they are considered visible in APP_CULL_DRAW. WHY ?
Are some optimizations done on the scene tree in APPCULL_DRAW ?
Note 1: the DCS nodes are not modified over the time.
Note 2: We do setTravMode( PFTRAV_CULL, PFCULL_VIEW | PFCULL_GSET );
AC_D:
=====
Nodes Visible: Bboards= 0 Bbqsets= 0
Total= 752 LODs= 0 fade= 0
Groups= 1 Layers= 0 Texts= 0
Geodes= 750 Lpoint Nodes: 0

Nodes App Cleaned:

A_C_D:

Culling in AC_D and A_C_D :
