To Polar

Converts Cartesian X/Y/Z coordinates to spherical form: a radius (distance from origin), a phase (azimuthal angle as a 0–1 turn), and an elevation (polar angle as a 0–1 turn). Useful for analyzing or transforming positions in radial terms.

Inputs

Port	Type	Default	Range	Description
X	Scalar	0.0	−1–1	Cartesian X coordinate
Y	Scalar	0.0	−1–1	Cartesian Y coordinate
Z	Scalar	0.0	−1–1	Cartesian Z coordinate

Outputs

Port	Type	Description
R	Scalar	Distance from origin
Phase (θ)	Scalar	Azimuthal angle as a 0–1 turn
Elevation (φ)	Scalar	Polar angle as a 0–1 turn. 0 = north pole (+Z), 0.25 = equator (XY plane), 0.5 = south pole (−Z)

Ideas

Convert position to polar, modify the radius, angle, or elevation with math nodes, then convert back with From Polar for radial distortion effects.
Extract the angle of a moving point to drive color or other parameters based on rotational position.
Feed 3D content through To Polar, manipulate in spherical space, then back through From Polar for spherical warping effects.

From Polar: the inverse conversion (angle/radius/elevation to X/Y/Z)
Arithmetic: modify radius, angle, or elevation values before converting back
