My application has multiple actors, each with it's own unstructured
grid. I'm using VTK 6.1.<br>
<br>
When a clip mesh filter is applied at a planar face of a model (i.e.
the clipping plane is flush with a planar component boundary) and a
second (composited) clip mesh filter is applied to its output and
configured so as to include all of the former's output, 'holes'
(i.e. missing triangles) appear in <br>
the rendered surface. Offsetting the first filter's clipping plane
by a very small amount (e.g. 0.00001) fixes the issue.<br>
<br>
First clip mesh result (ok):<br>
<img src="cid:part1.04080307.09060809@infolytica.com" alt=""
height="306" width="310"><br>
<br>
Second clip mesh (holes appear):<br>
<img src="cid:part2.08040309.02040307@infolytica.com" alt=""
height="285" width="312"><br>
<br>
Third clip mesh (holes again):<br>
<img src="cid:part3.05050501.00070808@infolytica.com" alt=""
height="294" width="313"><br>
<br>
At first I thought that it was a tolerancing issue. But since the
first clip mesh filter gives correct results, there's something
fishy going on when another clip mesh filter is added to the
pipeline.<br>
<br>
Has anyone seen this behavior and can you suggest a fix? Should I
submit a bug report?<br>
<br>
Thanks.<br>
