Operator Family

There are six Families of built-in Operators. Of the six families, five are basic operator families and one is the Component family which can further contain networks of operators. Components containing components form the TouchDesigner hierarchy and give rise to the operator Paths.

Within each operator family, "generator" operators have 0 inputs and create data, and "filter" operators have 1 or more input and filter data.

Each operator family is a unique color. Only operators of the same family (color) can be Wired together. Many operators have parameters that are references to operators in other families: Links. Also Exporting flows numeric data from CHOPs to all operators.


Custom Operators of type TOP, CHOP, SOP, and DAT can be created using C++, allowing you to extend TouchDesigner's functionality. They will show up in the OP Create Dialog under the 'Custom' tab.
