Summary
[edit]

The Parameter DAT outputs a table of parameter names and values of an operator, including custom parameters, from any OP type.

It can output pre-evaluated expressions, the Parameter Mode plus all attributes that define parameters - their type, label, ranges, menu items, limits, etc. in up to 24 columns of information.

Parameters - Parameter Page

Operators ops - The operators determine where to obtain the channels. Specify or more operator names or paths. Examples: wave1, slider*, constant[1-9] constant[10-19:2], ../base1. Or select the operators using the menu.   Parameters parameters - The list of parameters names (which can include wildcards) you want to get from the OP(s). One or more parameter, or * for all parameters. You can also specify a "NOT" selection with an ^. Or select the parameter using the menu. See Pattern Matching.   Include Op Name includeopname - Adds the OP name to the beginning of each parameter name in the table   Rename from renamefrom - See Pattern Matching.   Rename to renameto - See Pattern Expansion.   Custom custom - Output the operators' custom parameters.   Built-In builtin - Output the operators' built-in parameters.  


Parameters - Output Page

Toggles for information about the parameter and its value

Header header - Outputs the column headers.   Name name - Outputs the parameter name.   Value value - Outputs the evaluated parameter value.   Eval eval - Outputs the evaluated parameter value as a python object.   Constant constant - Outputs the current constant value of the parameter.   Expression expression - Outputs the current python expression of the parameter.   Export export - Outputs the export path of the parameter.   Mode mode - Outputs the current mode of the parameter (constant, expression, or export).   Style style - Outputs what format the parameter is (eg. Float for float parameters, Menu for menu parameters etc.).   Tuplet Name tupletname - Outputs the name of the tuplet the parameter is in. For example, tx on the Geometry COMP is a part of the 't' tuplet.   Size size - Outputs the size of the tuplet. For example, tx on the Geometry COMP would have a tuplet size of 3 since it's a part of the 't' tuplet with 3 parameters.   Path path - Outputs the path to the node.   Menu Index menuindex - If the parameter is a menu, then output the selected index of the menu.  


Parameters - Define Page

Toggles for information that define the parameter.

Min/Max minmax - Outputs the minimum and maximum values of the parameter. These values will clamp the value parameter to be within the range. If clampmin is 0 then the minimum will not clamp and the row/column entry will be 0. If clampmax is 0 then the maximum will not clamp and the row/column entry will be 1.   Clamp Min/Max clampminmax - Outputs whether or not the parameter has a clamped min or clamped max. If true, then the values are defined by min/max columns.   Norm Min/Max normminmax - Outputs the minimum and maximum values of the parameter in the interface (ie. the minimum and maximum values of a slider).   Default default - Outputs the default value of the parameter   Enabled enabled - Outputs whether the parameter is currently enabled   Read Only readonly - Outputs whether the parameter is currently read-only   Section section - Outputs whether the parameter has a section divider/separator (ie. line) above it.   Menu Names menunames - Outputs a list of the menu names for any menu parameters.   Menu Labels menulabels - Outputs a list of the menu labels for any menu parameters.  


Parameters - Common Page

Language language - - Select how the DAT decides which script language to operate on.

  • Input input - The DAT uses the inputs script language.
  • Node node - The DAT uses it's own script language.


Edit/View Extension extension - - Select the file extension this DAT should expose to external editors.

  • dat dat - various common file extensions.
  • From Language language - pick extension from DATs script language.
  • Custom Extension custom - Specify a custom extension.


Custom Extension customext - Specifiy the custom extension.  


Word Wrap wordwrap - - Enable Word Wrap for Node Display.

  • Input input - The DAT uses the inputs setting.
  • On on - Turn on Word Wrap.
  • Off off - Turn off Word Wrap.

An Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a command Script, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.

Any of the procedural data operators. OPs do all the work in TouchDesigner. They "cook" and output data to other OPs, which ultimately result in new images, data and audio being generated. See Node.

A text string that contains data (string, float, list, boolean, etc.) and operators (+ * < etc) that are evaluated by the node's language (python or Tscript) and returns a string, float list or boolean, etc. Expressions are used in parameters, DATs and in scripts.

Exporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.

A tuplet is the set of parameters that appear on one line of the parameter dialog. Tuplets occupy a page of parameters.

An Operator Family that contains its own Network inside. There are twelve 3D Object Component and eight 2D Panel Component types. See also Network Path.

The location of an operator within the TouchDesigner environment, for example, /geo1/torus1, a node called torus1 in a component called geo1. The path / is called Root. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.

The generic thing that holds an Operator, and includes Flags (display, bypass, lock, render, immune) and its position/size in the network. Whether you "lay down an Operator" or "lay down an Node", you're doing the same thing.
