<FONT face="Times New Roman, Times, Serif" size=3>Hi all,</FONT><BR>
<FONT face="Times New Roman, Times, Serif" size=3></FONT> <BR>
<FONT face="Times New Roman" size=3>I can`t see with good illumination 2 actors in the same renderer:</FONT><BR>
<FONT face="Times New Roman" size=3></FONT> <BR>
</FONT><FONT face="Times New Roman, Times, Serif"><FONT size=3>Actor 1: actor generated from a polydata created with vtkMarchingCubes.</FONT><FONT size=3> </FONT></FONT><BR>
<FONT face="Times New Roman, Times, Serif" size=3>Actor 2: actor generated from a polydata read from a </FONT><FONT size=2><FONT face="Times New Roman, Times, Serif" size=3>wavefront file (.obj read with vtkOBJReader). </FONT><BR>
<FONT face="Times New Roman, Times, Serif" size=3></FONT> <BR>
<FONT face="Times New Roman, Times, Serif" size=3>When I put all in the same renderer the actor 2 is shown too dark. I can see only the actor 1!</FONT><BR>
<FONT face="Times New Roman, Times, Serif" size=3></FONT> <BR>
<FONT face="Times New Roman, Times, Serif" size=3>In order to solve this, I tried 2 approaches without success:</FONT><BR>
<FONT face="Times New Roman" size=3></FONT> <BR>
<FONT face="Times New Roman, Times, Serif" size=3>Approach 1: Use of vtkLight</FONT><BR>
<FONT face="Times New Roman, Times, Serif" size=3>When I use vtkLight, the actor 2 can be seen, but the actor 1 becomes too clean. </FONT><FONT color=#c0c0c0 size=2><BR></FONT>
<FONT face="Times New Roman" size=3></FONT> <BR>
<FONT face="Times New Roman, Times, Serif" size=3>Approach 2: Use of vtkPolydataNormals in polydata of actor 2</FONT><BR>
<FONT face="Times New Roman, Times, Serif" size=3>When I use vtkPolydataNormals filter in polydata of actor 2, I can see both correctly in the same renderer. However the resulting polydata loses a lot of polygons! The polygons mesh becomes too bad...</FONT><BR>
<FONT face="Times New Roman, Times, Serif" size=3></FONT> <BR>
<FONT face="Times New Roman, Times, Serif" size=3>Does someone know how to solve this problem???</FONT><BR>
<FONT face="Times New Roman, Times, Serif" size=3></FONT> <BR>
<FONT face="Times New Roman, Times, Serif" size=3>Thanks!</FONT><BR>
