Try node.getBound() to see what that is set to.  If you use LODs, PagedLODs,
or ProxyNodes, you must set their center appropriately.

Subject: [osg-users] Frustum Cull

hi Robert
because when I set a small far , and move the model byond the far, the model
gets cliped, iit disapears but the number of drawables keeps the same, what
I mode the model outside the screen on the sides the number of drawables is
decreased

thank you
Ryven

Hi Ryven,

The DO_NOT_COMPUTE_NEAR_FAR does not affect view frustum culling.

View frustuming culling is only done on nodes and drawables, it doesn't cull
individual triangles.

What makes you think that view frustum culling isn't working?

Robert.
