Hi Nabil,<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">
Hello,<br>
I'm using geometry shader with OSG to do some operations on mesh using GPU.<br></span>
When i use /triangles_adjacency/  in the input layout, my shader crashes.<br>
I tried with /layout(triangles) in/  and it's running well.<span class=""><br>
<br>
Is there any configuration in OSG that i should use, or a pre-processing on the mesh to understand triangle adjacency?<br>
</span></blockquote>
You need to pre-process the mesh to get the adjacency information. There is no facility in OSG that I know of, wich does this for you.<br>
<br>
<br>
Cheers<br>
Sebastian<br>
