Could anybody explain me what is happening here ?
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.
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 ?
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
Sequences= 0 Lpoints: 0 omni= 0 uni=0 bi= 0
SCSs= 0 D= 1 F= 0
Nodes App Cleaned:
Total= 0
Groups= 0
Geodes= 0
Switches= 0
SCSs= 0 D=0 F=0
A_C_D:
======
Nodes Visible: Bboards= 0 Bbqsets= 0
Total= 1547 LODs= 0 fade= 0
Groups= 1 Layers= 0 Texts= 0
Geodes= 750 Lpoint Nodes: 0
Sequences=0 Lpoints: 0 omni= 0 uni=0 bi= 0
SCSs= 0 D=796 F=0
Nodes App Cleaned:
Total= 0
Groups= 0
Geodes= 0
Switches= 0
SCSs= 0 D=0 F=0
Culling in AC_D and A_C_D :
===========================
Cull: Nodes GSets
Total: 1548 750
Tested: 288 0
Reject: 1 0
Trivial-accept: 1525 750
Non-Trivial: 22 0
Note: We do setTravMode( PFTRAV_CULL, PFCULL_VIEW | PFCULL_GSET );
Thanks,
Isabelle
