I have a couple of vectors. However, they are not ordered in a regular 3D fashion. Nevertheless, regarding the manual "With the setting VectorPoints->All, ListVectorPlot3D instead shows vectors associated with the particular vector field data points given." So I guess MMA should be able to display the following example:

vectors = {{1, 1, 1}, {2, 0, 1}, {1, 2, 3}, {0, 2, 0}, {3, 1, 1}};
points = {{0, 0, 0}, {1, 0, 0}, {0, 1, 0}, {1, 1, 0}, {1, 1, 1}};
combo = Transpose[{points, vectors}];

ListVectorPlot3D[combo, VectorPoints -> points]

But plotting this, results in an empty box. Any hints?

EDIT: The data above are showing a MWE. I have in mind to plot in total 5000 vectors...

  • $\begingroup$ Not really. As far as I understand, Arrow affords starting and ending point of the vector. I have a direction (here as vectors) and the center position of the vectors (here as points). $\endgroup$

    $\begingroup$ Right, my mistake, like: Graphics3D[Arrow[{#, +##} & @@@ combo]]? $\endgroup$

  • $\begingroup$ Yeah, this is somehow what I want. Why isn´t ListVectorPlot3D able to show that? In addition to your above answer: How can I code the color of the arrows, for example linked with the Norm of the vectors $\endgroup$

Commands that start with "List" usually expect data to lie on a regular grid... I think the solution suggested in the comment by Kuba is great. Usually, I do it with

s = 0.1;
Graphics3D[Arrow[Transpose[{points, points + s vectors}]]]

where s is a scaling parameter.
