Get Angles (G Dataflow)

Last Modified: June 25, 2019

Computes the angles formed by sets of four points in an image or between sets of two points and a common vertex.

datatype_icon

points

Array of point-coordinate clusters.

If use vertex (no) is TRUE, four points at a time are considered when computing the angle, as shown in the leftmost figure. If use vertex (no) is FALSE, the angle made by two consecutive points in the array and the vertex is computed, as shown in the rightmost figure.

datatype_icon

vertex

Vertex point to use if the use vertex (no) option is TRUE.

datatype_icon

use vertex

Boolean that specifies if a vertex point is used while computing the angle.

True Use a vertex point while computing the angel.
False Do not use a vertex point while computing the angle.

Default: False

datatype_icon

error in

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.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

angles (degrees)

Array containing the computed angles in degrees.

datatype_icon

angles (radians)

Array containing the computed angles in radians.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
