Attribute Attributes

Information associated with SOP geometry. Points and primitives (polygons, NURBS, etc.) can have any number of attributes - position (P) is standard, and built-in optional attributes are normals (N), texture coordinates (uv), color (Cd), etc.

Attributes include information about an entity such as its color, velocity, normal, and so on.

Attributes can be attached to Vertices, Points, Primitives, or the whole geometry.

Point and vertex attributes are interpolated across primitives, allowing more local flexibility than primitive attributes (e.g. color). Vertex attributes deal with the situation where shared points need different values for the attributes at the boundary of primitives, like the seam of a polar texture map for example. Primitive colors typically take us less memory point colors, and point colors less than vertex colors.

Binding Binding

Binding is a Parameter Mode that ties two or more values together, where changing the value of any one of the bound values changes all of them. The actual value is stored in one place, whichever value is at the top of the bind chain, called the bind master. Parameters can be bind references, bind masters, or both. Table cells and bindCHOP channels can be bind masters only.

Bookmark Bookmarks

A pull-down list at the top of a network Pane containing jump-to Network Paths.

Bypass Bypass

An operator whose Bypass flag is set does nothing: All data from its first input flows through to its output unaffected.

Callback Callback

Some operators have a DAT docked to them that contains some python functions. These functions, called "callbacks", get called when something in the operator changes.

Channel Channel

A CHOP outputs one or more channels, where a channel is simply a sequence of numbers, representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. See also Export.

CHOP CHOP Channel Operator

An Operator Family which operate on Channels (a series of numbers) which are used for animation, audio, mathematics, simulation, logic, UI construction, and many other applications.

CHOP Sample Rate

samples-per-second of a CHOP. Each CHOP in your network has a sample rate, whether it is used or not. The overall timeline has a "frame rate", which is the number of animation frames per second, generally your monitor display frequency.

Clone Clone

Cloning can make multiple components match the contents of a master component. A Component whose Clone parameter is set will be forced to contain the same nodes, wiring and parameters as its master component. Cloning does not create new components as does the Replicator COMP.

Component Component COMP

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.

Connector Connector

The notch on the left and right of each Node that lets you connect a Wire from the output of one operator to the input of another operator of the same Operator Family.

Container COMP Container

The Container component type is a Panel Component that holds and displays any number of Panel Components (also known as Gadgets) in Panel.

Cook Cook

To re-compute the output data of the Operators. An operator cooks when (1) its inputs change, (2) its Parameters change, (3) when the timeline moves forward in some cases, or (4) Scripting commands are run on the node. When the operator is a Gadget, it also cooks when a user interacts with it. When an operator cooks, it usually causes operators connected to its output to re-cook. When TouchDesigner draws the screen, it re-cooks all the necessary operators in all Networks, contributing to a frame's total "cook time".

DAT DAT Data Operator

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.

Dependency Dependency

is the procedural mechanism in TouchDesigner, where if one piece of data changes, it automatically causes other operators and expressions to re-cook.

Designer Mode Designer Mode

You edit your networks in Designer Mode. See Perform Mode.

Dialog Dialog

Any floating window that is not a Pane or Viewer.

Display Flag Display Flag

The blue flag on Geometry components and SOP operators determines if the geometry contained in that operator is visible in node viewers and geometry viewer panes. See Render Flag.

Docking Docking Docked

Any node can be docked to another node. This helps organize networks as two node that are docked together will stay together when the dock parent is moved in a network editor. A docked node can be collapsed into a small icon under the dock parent, reducing network clutter.

Export Export

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.

Expression Expression

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.

Extensions Extensions

Any component can be extended with its own Python classes which contain python functions and data.

Filter Filter

Operators that have 1 or more input, like a Math CHOP, are called filters. See Generator.

Flag Flag

(1) Indicator of certain states of an operator (bypass, display, lock), or (2) option of a Tscript command.

Flag Render Flag

The purple flag on COMP and SOP nodes that determines if the node will be rendered in a Render or Render Pass TOP. The operator must also be listed in the Render / Render Pass TOP's 'Geometry' parameter.

Folder Folder

The operating system's holder of files and other folders (directories). It does not refer to operators within TouchDesigner. See Network Path.

Frame Frame

The term "Frame" is used (1) in the Timeline, (2) as a time-unit in CHOPs, (3) as a time-unit in TOPs, and (4) with movies images which are read and created with TOPs.

Frame Rate Frame Rate FPS

The frame rate that TouchDesigner's Timeline uses. Equal to the Frames per Second value project.cookRate.

The Graphics Processing Unit. This is the brains of the graphics card, and consists of 4 to hundreds of processors.

It's where TOPs are computed. It also runs CUDA programs.

Immune Immune

Every node has an Immune Flag, when on and the node is inside a Clone, it is not affected by any change to the clone, so you can store extra data in the clone or set a node to be ignored by the cloning process.

Every node has an Immune Flag, when on and the node is inside a Clone, it is not affected by any change to the clone, so you can store extra data in the clone or set a node to be ignored by the cloning process. Components also allow you to set Immune for the contents inside.

Instance Instance

(1) A Geometry Component can render its SOP geometry many times using CHOP samples, DAT rows, TOP pixels or SOP points, (2) An instance is an OP that doesn't actually have its own data, but rather just refers to an OP (or has an input) whose data it uses. This includes Null OPs, Select OPs and Switch OPs.

Internal Operators Internal Operators

Internal Operators (iOPs) provide a simple shortcut to a frequently-used operator, accessing from anywhere in that component.

Internal Parameters Internal Parameters

Internal Parameters act like local variables in a component. They provide a simple shortcut to collections of parameters that you create within a component, accessing from anywhere in that component.

Network Network

Every component contains a network of operators that create and modify data. The operators are connected by wires that define where data is routed after the operator cooks its inputs and generates an output.


TouchDesigner is WYSIWID - What You See Is What It's Doing. All nodes can have interactive viewers of their data.

Network Editor Network Editor

A pane type where networks of operators can be created and edited.

Network Path Path Network Path

The 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.

Panel Value Panel Value

The internal states of a panel component are Panel Values, and are accessed with a Panel CHOP, a OP.panel Python expression, or a Panel Execute DAT.

Parameter Parameter

Parameters in TouchDesigner are an operator's settings (numbers, menus, flags, strings, paths) which the user can alter. Parameters for any operator can be opened by right-clicking on the operator and selecting "Parameters..." A currently selected operator's parameters can be viewed in a Network Editor by pressing the keyboard shortcut 'p'.

Parameter Parameter Value

Parameter Value refers to the constant, the expression, the bind reference and the Parameter Mode that are used together to determine the evaluated parameter value.

Parameter Expression Parameter Expression

Parameter Mode Parameter Mode

Every Parameter can be in one of four modes: Constant Mode, Expression Mode, Export Mode or Bind (Binding) Mode.

Parameter Reference Parameter Reference

A parameter reference can be setup between any two parameters. This creates a link between the two parameters such that when one changes, the other will change automatically (known as "constraints" in other software). A Parameter reference is a type of Link.

Parent Parent

There are 2 kinds of parenting. The "parent component" is the component in which a node resides. The metaphor is extended to include grand parents, grand-grand parents, etc. The root / is the ultimate parent to all nodes. See also 3D Parenting and panel Parenting.

Parent Shortcut Parent Shortcut

A Parent Shortcut is a parameter on a component that contains a name that you can use anywhere inside the component to refer to that component using the syntax parent.Name, for example parent.Effect.width to obtain panel width.

Pattern Matching Pattern Matching

Matching strings using wildcard characters and bracketing. Useful in "Select" parameters to select multiple operators, paths, etc.

Pattern Replacement Pattern Replacement

Used in conjunction with Pattern Matching to replace all or portions of matched strings with new data. Used in places such as the Rename CHOP.

Point Point

Each SOP has a list of Points. Each point has an XYZ 3D position value plus other optional attributes. Each polygon Primitive is defined by a vertex list, which is list of point numbers.

Polygon Polygon

A polygon is a type of Primitive that is formed from a set of Vertices in 3D that are implicitly connected together to form a multi-edge shape.

A polygon is a type of Primitive that is formed from a set of Vertices in 3D that are implicitly connected together to form a multi-edge shape. Each Vertex is a reference to a Point in a Point List. Polygons in a Primitive List are part of the Geometry Detail, which is a part of a SOP.

Procedural Procedural

Is the chain-reaction mechanism of TouchDesigner, where if one piece of data changes, it automatically causes other dependent operators and expressions to re-cook and re-generate.

Projection Mapping Projection Mapping

A technique or workflow that allows for displaying content on often irregular shapes and surfaces.

Pulse Pulse

To pulse a parameter is to send it a signal from a CHOP or python or a mouse click that causes a new action to occur immediately. A pulse via python is via the ?'"`UNIQ--syntaxhighlight-0000000A-QINU`"'? function on a pulse-type parameter, such as Reset in a Speed CHOP. A pulse from a CHOP is typically a 0 to 1 to 0 signal in a channel.

To pulse a parameter is to send it a signal from a CHOP or python or a mouse click that causes a new action to occur immediately.

Some parameters are specifically Pulse-type parameters such as Reset Pulse in a Speed CHOP. A pulse via python is via the ?'"`UNIQ--syntaxhighlight-0000000B-QINU`"'? function on a pulse-type parameter, for example ?'"`UNIQ--syntaxhighlight-0000000C-QINU`"'?.

A pulse from a CHOP is typically a 0 to 1 to 0 signal in a channel exported to the Pulse-type parameter.

Quad Reprojection Quad Reprojection

Quad Reprojection renders pixel-perfect perspective-correct images for flat TVs and LED panels hung at any orientation.

Rendering Rendering

A 3D image created with the Render TOP. Also used more generally to include the compositing (with TOPs) to generate an output image.

Replicator COMP Replicator

Creates a new component for every line in a table. Unlike Clone, it automatically creates copies of a master component.

Resolution TOP Resolution

The width and height of an image in pixels. Most TOPs, like the Movie File In TOP can set the image resolution. See Aspect Ratio for the width/height ratio of an image, taking into account non-square pixels.

RMB Menu RMB Menu

The menu that appears when clicking the right mouse button on different parts of TouchDesigner. (Sometimes you need to be holding down Ctrl.)

Root Root

TouchDesigner is a hierarchy of components. "root" is the top-most network in the hierarchy. The Path is simply /. A typical path is /project1/moviein1.

Scope Scope

A parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator.

Script Script

A set of commands located in a Text DAT that are triggered to run under certain conditions. There are two scripting languages in TouchDesigner: Python and the original Tscript. Scripts and single-line commands can also be run in the Textport.

Shader Shader

The OpenGL code that creates a rendered image from polygons and textures. Shaders can be made of up to three parts: Vertex Shader, Geometry Shader and/or Pixel Shader, which are either embedded inside Materials, or placed in Text DATs and referenced to a GLSL Material.

Shortcut Shortcut

There are four types of shortcuts: Application Shortcuts that are built-in to TouchDesigner's authoring interface, Panel Shortcuts that you create for any custom built panels, Parent Shortcuts for accessing a component from within that component, and Global OP Shortcuts that access a unique component from anywhere in TouchDesigner.
