[Paraview] Object size in screenshots

[Moreland, Kenneth]

For the glyph filter, you want to use the sphere glyph and turn all scaling off.  One problem you might run into is that the glyph filter will place glyphs on all points in your mesh regardless of what type of cell is on it (0, 1, or 2D).

I think the warnings you are getting with the tube filter happen when you have large bends in the tube.  If the output looks OK, you should be able to ignore them.

The issue is that the points and lines sizes are measured in pixels, so the relative size goes down when you increase screen resolution.  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.

Converting them to 3d objects is a good idea. Here is my file:

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?

When I run the tube filter I get a bunch of these:


Bad normal s = 0.433013 0.75 0.5 n = 0 0 0

Could not generate points!

I'm not familiar with the tube filter - is there something else I need to do?

Thanks,

David
