Thank you very much for quick reply.
Although I tried it along with your advice , the beam diameter is
about 0.75 ( half width ). this value is smaller than I expected.
What parameter regulate the beam width
(size 0 wi ) ; "wi" ?
(amp-func (my-amp 1 (vector3 0 1)))) ; my-amp "1" ?
( if replacing to eg."wi") or (vector3 0 "1") ( if replacing to
eg."wi")?
The beam width is set by the sigma parameter of my-amp, which sets the
width of your (gaussian) beam; currently you are passing 1 for this.
The parameter in (size ...) sets the point where the gaussian tail is
truncated, not the width of the gaussian per se.
