Hi Robert,
Sorry, the camera manipulator is my own one, and the position is hard
coded for the home position.
I spend 3h yesterday night to find any explanation without success....
Thanks.
Regards,
Vincent.

Hi Vincent,
Could it be that your home position is changing with changes in the
sphere's dimensions/poistion, and the home position is affecting the
LOD selection.

Hi all,
I just get something very strange I cannot really understand :
In my scene, there is a graph will hundred of PagedLOD nodes, and no geodes.
I manually set the frustum of the viewer :
/
view->getCamera()->setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR
);
float divider = (float)(zNear/config->frustumNearPlan);
view->getCamera()->setProjectionMatrixAsFrustum (left/divider,
right/divider,bottom/divider, top/divider, zNear/divider,
config->frustumFarPlan);/
(near is 2 and far is 2e+07)
The scene render normally... there is no problem... BUT
When I add a little Sphere (osg::Sphere) on the scene (center 0,0,0 radius
1) before the render loop starts, the LODs never loads anything
and nothing but the Sphere is visible...
Because I set the frustum myself with the same values each time, I do not
understand why I didn't see the LODs nodes
The StatsHandler do not show the databasePager stats, which means there is
no cull on the LOD ? This is a real question I am not yet a
osg master...
To conclude, when I add the Sphere with a radius upper than 5000, the LODs
are visible... It really seems to be a wrong far plan frustum
value... but I verified it is always the same and never change from 2e+06
...
Any idea or suggestion could help me a lot :-)
Thanks.
Regards,
Vincent.
