Chapter 343: Cylindrical

Core Idea

This class can be used to represent points in 3D space as Cylindrical coordinates.

Key Concepts

• radius : number: The distance from the origin to a point in the x-z plane.
• theta : number: A counterclockwise angle in the x-z plane measured in radians from the positive z-axis.
• y : number: The height above the x-z plane.

Reference Tables

Constructor

Signature
new Cylindrical( radius : number, theta : number, y : number )

Properties

Property	Description
.radius : number	The distance from the origin to a point in the x-z plane.
.theta : number	A counterclockwise angle in the x-z plane measured in radians from the positive z-axis.
.y : number	The height above the x-z plane.

Methods

Method	Description
.clone() : Cylindrical	Returns a new cylindrical with copied values from this instance.
.copy( other : Cylindrical ) : Cylindrical	Copies the values of the given cylindrical to this instance.
.set( radius : number, theta : number, y : number ) : Cylindrical	Sets the cylindrical components by copying the given values.
.setFromCartesianCoords( x : number, y : number, z : number ) : Cylindrical	Sets the cylindrical components from the given Cartesian coordinates.
.setFromVector3( v : Vector3 ) : Cylindrical	Sets the cylindrical components from the given vector which is assumed to hold Cartesian coordinates.

Key Takeaways

1. Most relevant properties: radius, theta, y.
2. Key methods: clone, copy, set, setFromCartesianCoords.
