# 3D vectors in matlab questions

I am calculating the velocity of the air in front of a wing. I would like to plot the 3D vectors of the velocity on the same plot as the geometry of the wing. I have the two plots separately but I was wondering if there was anyway I could superimpose one on the other? Currently the geometry is plotted using fill3(X,Y,Z,'w') and the velocity vectors are plotted using quiver3(x,y,z,u,v,w).

I was also wondering it it were possible to indicate the magnitude of a vector other than the relative size of the arrow when using quiver3. Is there a way that I can give different arrows different colors and a color bar to represent the magnitudes or perhaps pick a few of the arrows and label them with their magnitude?
