Dear Mathematica experts, I am very new Mathematica user and have one problem which is for me impossible to solve. I must define geometric shape by set of points in XY plane and than rotate that shape (points) in steps of 1 deg around Z axis for 3 or 4 revolutions, at the same time that shape must be resized (magnified) by sale fator R for 1 deg reolution step, and translated downward Z axis by translation factor T for 1 deg revolution step. All three transforations must be done at the same time. That will generate shape similat to snail shell. At the end must read all coordinate points generated. I do not want to render or draw generated shape but only to have coordinates of all the points generaded from the initial points. I do not know is it possible to do something like that with Mathematica. I will appreciate any help.
