ArcTangent 2 6.003

This component is obsolete and its use in filters is not recommended. Use the recent version of the component.

The ArcTangent 2 component calculates the channel-wise atan2 function of the color supplied by the Source input. The alpha channel is not processed and is taken unchanged from the Point Y input.

ArcTangent 2 is a map component, it can be located in the RGB Math category on the Components Bar. This component can output HDR colors. Like other RGB Math components, this component processes its inputs on a channel-wise basis, treating RGB channel values as signed floating-point numbers. For more information, see How Math Components Work.

Point Y: Map Input (HDR)

Provides the color defining one of the points to calculate atan2. This input can accept HDR colors.

Point X: Map Input (HDR)

Provides the color defining the other point to calculate atan2. This input can accept HDR colors.

Units: Numeric Input

Specifies the unit of measurement: degrees, radians or rotations (one rotation is equivalent to 360 degrees).
