You can create a cable by dragging from a node’s output port to a compatible input port or from a node’s output port to a compatible input port.
Compatible ports are those that output and accept matching or convertible types of data. Compatible ports are highlighted as you drag your cable, so you know where it’s possible to complete the connection.
If you complete your cable connection between two ports whose data types are not identical, but that are convertible using an available type converter (e.g., vuo.math.round for rounding real numbers to integers), that type converter will be automatically inserted when you complete the connection.
Sometimes existing cables may also be re-routed by dragging (or “yanking”) them away from the input port to which they are currently connected. It is possible to yank the cable from anywhere within its yank zone. You can tell where a cable’s yank zone begins by hovering your cursor near the cable. The yank zone is the section of the cable with the extra-bright highlighting. If no yank zone is highlighted, you’ll need to delete and add back the cable.
