The Velocity 3D node enables you to calculate the current velocity of a point moving in a 3D space as well as the delta of its crossed distance.
This node can be found under Nodes > Filter > Vector > Velocity 3D
Choose an input node from the drop-down or enter a numeric value for the X-, Y- and Z-coordinates of the tracked point.
If you want to track a two or one dimensional movement, select only the respective axis and leave the others on "0"
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).
The Node generates the following output:
- Units per second (velocity)
