You can use a boundingBoxVisitor on the node in question.<br>

<div dir="ltr">Yes, good idea. That should work. I can't really
override the computeBoundingBox as I can't change the object
hierarchy easily.<br>

<div> Hi Andrew,<br>
<br>
you can use "setInitialBounds" to define your precompiled
bounding box.<br>

<div>Hi,</div>
<div>I am using a simple displacement vertex
shader to animate a displacement field on a
geometry.</div>
<div><br>
</div>
<div> I am having an issue where during the
animation the geometry is getting clipped by the
near/far planes that are automatically
maintained by OSG - obviously OSG knows nothing
about the displacements of the shader.</div>
<div><br>
</div>
<div>Any suggestions as to solve this issue in the
most simple manner. I would like to avoid having
to maintain my own near/far planes. I was hoping
OSG had a user-definable "fudge" factor for
near/far...<br>
