[Paraview] Object size in screenshots

[Moreland, Kenneth]

1) When I set the glyph filter to sphere, it is placing spheres only at the 20 points on the "grid" in that file, not at the vertex where all the lines meet. There are 21 points in the file - so I would expect it to put a sphere at all 21 points. That is what I was trying to explain last time, it seems to be glyphing Vectors: Normals, not points. I can't change the "Vectors" drop down box to anything except "Normals", and the scalars drop down box is disabled. When I turned "Scale mode" to "off" as you recommended, the 21st sphere showed up - but doesn't it still seem odd that you have to set it to glyph normals even though you want to glyph points?

Normals are just a field on the points.  The glyph filter can orient and scale glyphs by any normals.  As I stated before, you should turn off scaling.  You can also turn off orientation, although with spheres you shouldn't notice anything different.

2) I guess I forgot to mention that the tube filter does not produce any output, in fact my render window is completely empty after applying the filter. So I guess I should not ignore the errors in this case haha!

Hmm.  I've never seen that before.  The tube filter seems to be doing something special with normals, but I don't know what.  Perhaps someone more familiar with the guts of the tube filter can comment.
