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

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?

Hello
how can I set the far and near of the frustum? I have set the perspective using,
viewer.getCullSettings().setComputeNearFarMode(osgUtil::CullVisitor::DO_NOT_COMPUTE_NEAR_FAR);
viewer.setSceneData(processed_model.get());
viewer.realize();
viewer.setLensPerspective(40.0, 30.0, 0.5, 1.0);
but this way, opengl clips the geometry, but there is no frustum cull
by osg, the primitives and triangles are just the same. I can cull if
I don't set DO_NOT_COMPUTE_NEAR_FAR, bu this way I can't set the far
and near.
Can someone help?
sorry about the bad english
thanks
