One easy way around this is to covert the points/lines into 3D objects. Points can become spheres with the glyph filter and lines can become tubes with the tube filter. I believe the point sprite plugin can also efficiently render points as spheres with radii defined in world space. I have seen an example of plugin that can render lines as tubes directly (at least with correct lighting), but I don’t know where to (or if you can) get it.<br>

<br>Converting them to 3d objects is a good idea. Here is my file:<br><a href="http://rpi.edu/~doriad/Paraview_List/lines.vtp">http://rpi.edu/~doriad/Paraview_List/lines.vtp</a><br><br>When I run a glyph filter, it seems to want to glyph the normals, not the points. If I change it to "sphere", the desired result is obtained, but that seems a bit wacky. Shouldn't I be able to select "Points" somewhere?<br>
<br>When I run the tube filter I get a bunch of these:<br><br>
