[Paraview] details on glyph scaling

[Moreland, Kenneth]

Well, gosh, Tim. If you put it that way I wouldn't bet my life on it.

If the glyphs look wrong, it should be straightforward to check if the underlying vectors match. For example, if you are seeing vectors that look ridiculously large or small, you can use the Find Data dialog to see if the magnitude of any vectors are beyond some expected range. If you see a particular glyph that looks wrong, select the source data under it and look at the actual values of the vector.

Thanks for the response, Ken.

Are you absolutely, 'no-other-possibility' sure? I ask because my visualizations are non-sensical if this is the case, indicating that I may have more serious issues up the pipeline. I ask for you to re-confirm because before I sent the previous message, I had found many complaints online about the user-friendliness of glyph customization..

Thanks,

Tim

Set the Scale Factor to 1 and the Scale Mode to vector. That should size
the arrow glyph to the length of the vector.
