The Distance 2D filter node enables you to easily measure the distance between two points 1 and 2 in a two dimensional coordinate system.

This node can be found under Nodes > Filter > Vector > Distance 2D

## Node properties

### X1 and Y1:

Choose an input node from the drop-down or enter a numeric value for the X and Y coordinates of the first point.

### X2 and Y2:

Choose an input node from the drop-down or enter a numeric value for the X and Y coordinates of the second point.

## Node control

With Widget Designer version 6, all nodes support so called node commands. Node commands access functions (i.e methods) from a node and / or set a parameter (i.e. property).

Enter "node", followed by the according ID and a dot and a list will pop up showing all available commands for the node. For instance, Node1.TintColor.SetRGB(125,0,255), colors the node in purple.

In addition, the node properties with a parameter ID (the small superscript number) can be edited via the command Node1.SetParam(ID,new Value) or WDNodeSetParam(NodeID,ParamID,Value).

## Node output values

The Node generates the following output:

- Result (distance)

- UnitsPerSec (velocity with which the points are moving towards each other / away from each other)
