<TITLE>RE: [vtkusers] Strange problem - All of my triangle mesh is not d isplayed (Bug? )</TITLE>

<P><FONT SIZE=2>Hi! </FONT>
<BR><FONT SIZE=2>Thanks for your quick reply!</FONT>
<BR><FONT SIZE=2>I want all of my data to be displayed as polygons (triangles). In the original dataset there are a number of points that are invalid and should not be a part of the polydata object. But these points are never used when I define the triangle cells in the vtkCellArray ( I'm sure of that! :) As I mentioned earlier I'm pretty sure that my poly data objects is correct - that all points that should be, are a part of one or more triangles. The thing is that when I use a smaller data set OR when I decimate the polydata object of a bigger one, everything works fine. If I decmate say only 5% I can see some more of the data and if I decimate abou t 10% I can see all of it. It seems that if the polydata that is sent to the mapper is too big the bottom is not shown. And by the bottom a mean the triangles that was last defined in the CellArray - those would always be at the bottom in my application. I mentioned the thing about the vtkLODActor to point out that all the points that should be, really are in the polydata object and I mentioned the part about decimation to point ot that the triangles also seems to be defined correctly otherwise the decimation wouldnn't work so well (or?). I'm just not comfortable with having to depend on triangle decimation before I can display all of my data.</FONT></P>
<P><FONT SIZE=2>And another thing - I just tried the SetRepresentationToPoints(); on my vtkProperty object, but the problem remains.</FONT>

<BR><FONT SIZE=2>Any suggestions?</FONT>
