Hi,
I am stuck with the following problem:
I am trying to display three data sets, a 3-D vector (v) and
two scalars (a and b), all three given for a set of points in
3-D space. My data looks something like:
data = { {{x0,y0,z0}, {vx0,vy0,vz0}, a0, b0},
{{x1,y1,z1}, {vx1,vy1,vz1}, a1, b1},
...
{{xi,yi,zi}, {vxi,vyi,vzi}, ai, bi},
... }
I would like to have a 3-D display with an arrow at each point
{xi, yi, zi}, the arrow being parallel with vi and its length
and colour representing the values of ai and bi respectively.
I have tried using ListPlotVectorField3D which almost does the
job, but not quite. Am I missing something, or perhaps just asking
for too much?
Any help would be much appreciated...
John
