The use of a spiral phyllotaxis pattern produces uniform samples covering any surface of revolution. In principle, any other distribution of integration points can also be used as long as suitable quadrature weights can be found. If a uniform (or approximately uniform) sampling strategy is used as is the case for <code>makeCartBowl</code>, the quadrature weights are the same for all integration points and are easy to calculate. More details are in the <a href="http://bug.medphys.ucl.ac.uk/papers/2019-Wise-JASA.pdf">corresponding paper</a>.</p> <p>Brad </p> http://www.k-wave.org/forum/topic/kwavearray#post-7665 Sat, 27 Jun 2020 14:25:59 +0000 jackYANG 7665@http://www.k-wave.org/forum/ <p>Hi Brad,<br /> I have seen the makecartbowl in Kwavearray_alpha0.1, I would like to ask you why you choose to arrange the elements in such a way as the pepe spiral. What are the advantages of this way? Have you ever considered the Archimedes spiral?Thanks. </p>
