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>
