I have a simple question but couldn't find an answer.<br>
<br>
My geode is assigned a geometry shader that starts with<br>
<pre style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" color:#ff0000;"> layout</span>(lines_adjacency)<span style=" color:#c0c0c0;"> </span><span style=" color:#808000;">in</span>;
</pre>
For drawing geometry 1 I use <br>
<span style=" color:#c0c0c0;"> </span>
geometry1->addPrimitiveSet(<span style=" color:#808000;">new</span><span
style=" color:#c0c0c0;"> </span><span style=" color:#800080;">osg</span>::<span
style=" color:#800080;">DrawArrays</span>(<span style="
color:#800080;">osg</span>::<span style=" color:#800080;">PrimitiveSet</span>::<span
style=" color:#800080;">LINE_STRIP_ADJACENCY</span>,<span style="
color:#c0c0c0;"> </span><span style=" color:#000080;">0</span>,<span
style=" color:#c0c0c0;"> </span>count));
<br>
<br>
That works absolutely fine.<br>
<br>
For drawing geometry 2 in the same geode I use <br>
<span style=" color:#c0c0c0;"> </span>
geometry2->addPrimitiveSet(<span style=" color:#808000;">new</span><span
style=" color:#c0c0c0;"> </span><span style=" color:#800080;">osg</span>::<span
style=" color:#800080;">DrawArrays</span>(<span style="
color:#800080;">osg</span>::<span style=" color:#800080;">PrimitiveSet</span>::<span
style=" color:#800080;">TRIANGLE_FAN</span>,<span style="
color:#c0c0c0;"> </span><span style=" color:#000080;">0</span>,<span
style=" color:#c0c0c0;"> </span>count));
<br>
<br>
Is the geometry shader just skipped for the second geometry? Or must
I assign an individual shader for each geometry?<br>
This might be a big slowdown because I have really many of those
geodes.<br>
Is it possible to define 2 geometry shaders with different layouts
in one shader program?<br>
<br>
Thanks for any hints.<br>
