Point in Polygon (G Dataflow)

X-coordinates of the vertices of the polygon. You must specify at least three elements in this input.

Y-coordinates of the vertices of the polygon. You must specify the same number of elements in y and x.

X-coordinate of the point.

This input accepts the following data types:

• Double-precision, floating-point number
• 1D array of double-precision, floating-point numbers

Default: 0

Y-coordinate of the point.

This input accepts the following data types:

• Double-precision, floating-point number
• 1D array of double-precision, floating-point numbers

Default: 0

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

Accuracy of verifying whether a point lies on the boundary.

If the value you specify in tolerance is less than 0, this node sets the value to 1E-09.

Default: 1E-09

Position of the given point relative to the polygon.

This output can return the following data types:

• Ring
• 1D array of rings

Error information.

The node produces this output according to standard error behavior.
