Ib, I think he is using the code Lutz-Peter Hooge
posted to povray.text.scene-files 8. Dec. 2001 for
his "Lissajou-Knot generator":

And if that is so, then he should rewrite the
macro like this (for the final POV-Ray v3.5):


#macro Method3(T)

  <
    R*sin(A*T)*pow(sin(B*T), exp_X),
    R*sin(A*T)*pow(cos(B*T), exp_Y),
    R*pow(sin(A*T), exp_Z)
  >

#end
