NAME

map_cart_cyl - a class converting Cartesian to cylindrical coordinates

DESCRIPTION

This class is used to convert Cartesian 3D coordinates (x,y,z) to cylindrical coordinates (r = sqrt(x^2+y^2), phi = acos(x/r), z). It is not instanced.

SUPERCLASS

object

MESSAGES

: (x, y, z) Sets Cartesian coordinates (x, y, z) of a converted point.

! Returns cylindrical coordinates of the point set by ":" message.

EXAMPLE

vector new:a = [map_cart_cyl : (1,2,3) !] print!;
