The Atan2 node returns the 2-argument arctangent of the point with the input X and Y coordinates. The output value is the angle between the positive x axis and the point in the Cartesian coordinate system.
Variants
There are many variants of this node. The simplest take 2 scalar numeric-typed values. Some more complicated variants take one scalar and one vector or two same-sized vectors. In each case, the output has the same dimensions as the highest dimension input. Values are calculated element-wise, for example:
If the input Y is 1 and input X is [2;3] the output will be [Atan2(1,2);Atan2(1,3)].
Similarly if the input Y is [1;2] and the input X is [3;4] the output will be [Atan2(1,3);Atan2(2,4)].
Inputs
Y (Pseudo-Generic)
Input Y coordinate value.
X (Pseudo-Generic)
Input X coordinate value.
Outputs
* (Pseudo-Generic)
2-argument arctangent of Y and X.
