Ouch! That is some seriously complicated geometry! </blockquote><div><br>yes, i am working with biologists... complex is the name of the game! <br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
I think you are<br>running into the limitations of the depth-peeling algorithm that is<br>used to render transparent geometry. You can try to increase some of<br>these limits by recompiling ParaView. In the source code, you have to
<br>edit VTK/Rendering/vtkRenderer.cxx and change MaximumNumberOfPeels on<br>line 119 to something higher, maybe 10-20. However, this will reduce<br>rendering speed because each peel roughly corresponds to 1 render.</blockquote>
<div><br><br>i am not sure this is the problem... when i look at the source for<br>vtkRenderer.cxx in ParaView2.6 and ParaView3, these fields are<br>exactly the same:<br>
<br>
this->MaximumNumberOfPeels=4;<br><br>
and the exact same dataset on the exact same machine appears<br>
as expected in ParaView2.6 (i.e. without these raster artifacts). or<br>is there something i am missing here? i looked at the diff between<br>the two files, and there is a bunch of different stuff (version number<br>is
1.231 versus 1.233) including a bunch of calls where, in 1.231 <br>there are references to "Render translucent geometry" that in ver<br>1.233 it says "Render translucent polygonal geometry". these sorts
<br>of things appear to make up a majority of the diff b/t the versions. i<br>can post the diff if it will be useful (though i am sure everyone here<br>can easily generate it themselves).<br><br>thanks again,<br>bryan<br>
