| == ATan2 Node ==
| | Shader creation concepts. |
|
| |
|
| The ATan2 node outputs the arctangent of the division [[#paramA|A]]'''/'''[[#paramB|B]]. If (B,A) defines a (x,y) vector then using this operator returns the angle in radians it does with the x-axis <br/>
| | [[Category:Tutorials]] |
| '''NOTE:''' ATan2 between multi-channel data types are done per-channel. If ''A'' and ''B'' have different channel amounts a cast is done to match the one with the most amount of channels.
