Re: Plotting 3D vectors

[Etienne Grossmann]

Hi Gad,

this also works

 Z=[0;0;0]; A = randn(3,1); B = randn(3,1); N = cross (A,B); 
 vrml_browse ([vrml_cyl([Z,A],"arrow","col",[1 0 
0]),vrml_cyl([Z,B],"arrow","col",[0 1 0]),vrml_cyl([Z,N],"arrow")])

If you have octave-forge and freewrl (there's @ least a Debian
package).

  Hth,

  Etienne
