% QUIVER3d *True* 3D quiver plot.
%
% This function provides an improved technique for visualizing 3D
% vector fields. It relies on the efficient use of a single patch
% call and lighting effects to provide depth cueing.
%
% QUIVER3D(X,Y,Z,U,V,W) plots velocity vectors as arrows with components
% (u,v,w) at the points (x,y,z). The matrices X,Y,Z,U,V,W must all be
% the same size and contain the corresponding position and velocity
% components. QUIVER3D automatically scales the arrows to fit.
%
% QUIVER3D(X,Y,Z,U,V,W,COLOR) provides an input argument for coloring
% the vecotors. The COLOR argument can be a single color ([1x3] or
% [3x1]), and indexed color ([1xN] or [Nx1]), or a true color ([3xN or
% Nx3). Where N is equal to the number of elements in X or Y or Z or...
%
% QUIVER3D(X,Y,Z,U,V,W,COLOR,S) automatically
% scales the arrows to fit and then stretches them by S.
% Use S=0 to plot the arrows without the automatic scaling. S=1
% provides simple autoscaling.
%
% QUIVER3D(X,Y,Z,U,V,W,COLOR,S,N) provides an input that defines the
% density of the tessellation used in generating the arrows. If N is
% high (>15) then the rendering time can be long and interactivity of
% the rendering can be slow. If N<15 the rendering is generally quick
% for ~100s of vectors. The default is N=15;
%
% H = QUIVER3D(...) returns a patch object of the arrow cluster.
%
% Example:
% quiver3d; % Generates a sample output of the function.

Minor modifications. 1) Eliminated call to rot3d. It should have been commented out. 2) Changed calculation of arrow body diameter to be based on vector magnitude, not position magnitude.
