The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.\n\n\n\nAn Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a python Script or GLSL Shader, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.\n\n\n\nThe location of an operator within the TouchDesigner environment, for example, /geo1/circle1, a node called circle1 in a component called geo1. The path / is called Root. This path is displayed at the top of every Pane, showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.\n\n\n\nEvery operator in TouchDesigner has a set of control Parameters that can be integer or floating point numbers, menus, binary toggles, text strings or operator paths, which determine the output of the operator.\n\n\n\nTouchDesigner is a hierarchy of components. \"root\" is the top-most network in the hierarchy. The Network Path or Path for root is simply /. A typical path is /project1/moviein1.\n\n\n\n\n\n\n\n\nRetrieved from \"https://docs.derivative.ca/index.php?title=Lag_CHOP&oldid=24050\"", "tooltip": "", "help": "", "units": "", "examples": [], "isReadOnly": false, "isAdvanced": false, "isHidden": false, "isAnimatable": true, "isExpression": false, "isPython": false, "dependsOn": [], "affects": [], "linkedTo": [], "expressionLanguage": "", "defaultExpression": "", "commonExpressions": [], "order": 0, "isVisible": true, "conditionalDisplay": null, "isValid": true, "validationErrors": [], "lastUpdated": "2025-08-08T00:37:45.749Z", "rawData": {}, "sourceElement": null }, { "id": null, "name": "Method", "label": "Method", "group": "General", "page": "", "type": "float", "dataType": "number", "style": "", "defaultValue": null, "minValue": null, "maxValue": null, "step": null, "menuItems": [], "menuLabels": [], "allowCustom": false, "maxLength": null, "pattern": null, "isArray": false, "arraySize": 1, "dimensions": 1, "description": "lagmethod - - The method by which lag is applied to the channels.\n\n value - Up is defined as an increase in values of the input channels, and down is a decrease in values of the inputs. amp - Up is defined as an increase in amplitude (moving away from zero) and down is defined as a decrease in amplitude (moving towards zero) of each input channel. mag - All the input channels are treated as components of one vector, and each operation is applied to the vector as a whole.
