 Graphics`PlotField3D` This package allows the graphical display of vector fields in three dimensions. The vector field can be represented by lines or arrows which can display direction and magnitude. Plotting vector fields in three dimensions. This loads the package. In[1]:= < 5, VectorHeads -> True] A variable range specification of the form x,xmin,xmax,dx adjusts the evaluation grid by specifying step sizes of dx in the direction. An analogous specification in the and ranges will adjust the evaluation grid in those directions. You can also adjust the evaluation grid by setting the PlotPoints option. Vector field plots from lists. This gives an array of random vectors. In[5]:= array = Flatten[ Table[ {{i, j, k}, {Random[Real, {-1, 1}], Random[Real, {-1, 1}], Random[Real, {-1, 1}]}}, {i, 7}, {j, 7}, {k, 7}], 2]; This displays the vectors. In[6]:= ListPlotVectorField3D[array] It is often hard to arrange the number of points to have enough samples without making the image overly complex. One way to overcome this is to construct an animation that rotates the whole image.
