<div dir="ltr">Having inner surface is not an issue especially if you don't put any transparency. The draw back will only be that you try to draw more data that you truly need and depending on your data size, this could affect the rendering performance. But other than that, there is no issue.</div><br><div class="gmail_quote"><div dir="ltr">On Mon, Jul 30, 2018 at 5:33 AM marf <<a href="mailto:marvin.huber@basf.com">marvin.huber@basf.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Thanks again, I previously tried filtering out duplicate faces and found an<br>

Whereas, when looked at it from another angle you can clearly see, there are<br>
no more inner faces present (which also HAS to be the case, since I slim<br>
down the amount of rendered faces from 38.000 to 20.000 without effecting<br>
the outer surface)<br>

Do you have any idea whats going on there? I apply a scalar to the polydata<br>
and then color it using a vtkLookupTable and that works perfectly otherwise.<br>
Also, the scalardata is per point, and since every point is on the surface<br>
in my case, the should not change with changing faces right?<br>
