Calibrates the meter or gauge using three points on the meter: the base of the needle, the tip of the needle at its initial position, and the tip of the needle at its full-scale position.
It calculates the position of the points along the arc covered by the tip of the needle. Use this node with meters or gauges equipped with a dark needle on a light background or with a light needle on a dark background.
Reference to the source image.
Cluster containing the coordinates of the base of the needle.
Point cluster containing the coordinates of the tip of the needle in its initial position.
Point cluster containing the coordinates of the tip of the needle in its full-scale position.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Reference to image in.
Point cluster containing the coordinates of the rotation center of the needle.
Array of point clusters containing the coordinates of the points along the arc traced by the tip of the needle.
