Wires are the colored lines that connect the output of a node to the inputs of other nodes in a network. You can think of wires as passing the data from one node to another.
A second type of wire is the Hierarchy Wire that connects the connectors on the top/bottom of 3D Components and 2D Panel Components, and forms the parent-child relation of these components.
Wires always connect nodes in the same Family: A wire between 2 CHOPs exposes the set of channels of the source CHOP to the destination CHOP. A wire between 2 TOPs exposes the image of the source TOP to the destination TOP. Left-right Data Wires occur on CHOPs, TOPs, SOPs, DATs and occasionally MATs.
To create a wire:
- Left-click on a node's input or output.
- Move the cursor to the output or input of the node you wish to connect to.
- Click a second time to complete the connection.
- Left-click on a node's input or output, and while holding it down, drag the cursor to the output or input of the node you wish to connect to.
- Release the left button.
When the cursor is over a connecting wire, it will highlight in yellow. In this highlighted state, on the wire you can
- MMB (middle mouse button click) to get info for the incoming node
- RMB to bring up a menu that allows you to
- insert an operator via the OP Create Dialog
- select the source node
- select the destination node
- disconnect the wire
Wires display animated dashed lines to provides visual feedback as to which nodes in a network are cooking. The animated dashed lines represent the flow of data between nodes.
Tip: Wires can be displayed in two modes: spline curves and straight lines. Pressing the hotkey "s" (straight) in a Network Editor pane will toggle between these two modes. You can also toggle the setting by using the "Link Straight" menu option from the Network Editor's context menu.
Note: When an operator cooks and data is generated, if it is connected by a wire to another operator, it doesn't actually pass or copy its data to the destination - it only informs the destination of where to get its data to operate on.
