Summary	0014484: Glyph3D source is not being displayed accurately
Description	I’m using a glyph3D to display some polydata and I noticed that the line does not go through the center of each of the spheres in the glyph. They are both using the same polydata.

Notes

Investigating problem:

Works in ParaView and with a little program I wrote. It looks to be an application integration error. I'm guessing the pipeline is not updating properly (since the glyphs were not connected to the Glypher via a connection/port (i.e., pGlyph->SetInputData(pEditingPointData->GetOutput()); may be the problem in your application).

Here is the program....I'll attach an image somewhere.
