Arc Tangent 2

Overview

The Arc Tangent 2 Node takes two Float values, yy and xx, and returns atan2(y,x)atan2(y,x). The result can be obtained in degrees (°) or radians (rad).

The function atan2(y,x)atan2(y,x) is of common use in computer science and can be equivalently defined as:

  • The angle θ\theta in the Euclidean plane between the positive XX axis and the ray connecting the origin and the point (x,y)(x,y).

  • The phase θ\theta of the complex number x+iyx+iy. That is, the angle θ(π,π]\theta \in (-\pi, \pi] such that x=rcosθx=r\cos\theta and y=rsinθy=r\sin\theta, where r=x2+y2r=\sqrt{x^2+y^2}.

Scope: Project, Scene, Function, Prefab.
