example :

  phi=[0:0.1:2*3.15];
  theta=[2*3.15:-0.05:0];
  [x,y,z]=eval3dp(tore,theta,phi);
  plot3d(x,y,z,alpha=75,theta=45)
  a=gca();//"axes" courant
  p=a.children(1);//Plot3d
  p.color_mode=10;//dessus bleu

  //on ajoute une sphère au tore
  [x,y,z]=eval3dp(sphere,theta,phi);
  plot3d(x,y,z,alpha=75,theta=45)
  p=a.children(1);//Plot3d
  p.color_mode=4;//dessus cyan
