Attribute Attributes Information associated with SOP geometry. Points and primitives (polygons, NURBS, etc.) can have any number of attributes - position (P) is standard, and optional are normals (N), texture coordinates (uv), color (Cd), etc. Attributes include information about an entity such as its color, velocity, normal, and so on.

There are many different attributes. Some of the most common ones are discussed below. Attributes can be attached to vertices, points, primitives, or the whole geometry. Since there are usually more vertices than points, having a vertex attribute will consume more memory than a point attribute. Similarly, since there are usually more points than primitives, having a point attribute will consume more memory than a primitive attribute. However, point attributes are interpolated across primitives, allowing more local flexibility than primitive attributes (e.g. color). Also, vertex attributes deal with the situation where shared points need different values for the attributes, like the seam of a polar texture map for example.

Backdrop Backdrop The Backdrop is the grid of node viewers that are visible behind the Network, set by turning on Display Flags and the network RMB -> Display... Backdrop OPs. The Backdrop is the grid of node viewers that are visible behind the Network, set by turning on Display Flags and the network RMB -> Display... Backdrop OPs.
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.
Gadget Gadget The component types that are used to make Panels: Button, Slider, Field, Container, Select. Gadgets are also known as Panel Components. see also Object.
Generator Generator Operators that normally have 0 inputs, like a Noise CHOP, are called generators. See Filter.
Geometry COMP Geometry The 3D data held in SOPs and passed for rendering by the Geometry COMP.
Geometry Spreadsheet Geometry Spreadsheet Currently, use a SOP to DAT to look at SOP point/polygon XYZ and other attributes. Formerly a Pane type.

Global OP Shortcut Global OP Shortcut A name for a component that is accessible from any node in a project, which can be declared in a component's Global Operator Shortcut parameter.
GPU GPU The Graphics Processing Unit. This is the high-speed, many-core processor of the graphics card/chip that takes geometry, images and data from the CPU and creates images and processed data. 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 the Immune flag is 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 a clone.
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 within a component, from anywhere in that component.
Internal Parameters Internal Parameters Internal Parameters provide a simple shortcut to parameter collections within a component, from anywhere in that component. They act like "persistent local variables".
Interoperability Interoperability, Interops The devices, protocols and software tools that TouchDesigner interfaces to, via native Operators and Palette components. The devices, protocols and software tools that TouchDesigner interfaces to, via native Operators and Palette components.
Keyframe Keyframe A frame within the Animation component which holds a channel value, slope, acceleration and interpolation type, used to determine the values of the channel which are not keyframes.
Layout Layout (1) The TouchDesigner window is made of a menu bar at the top, a Timeline at the bottom, plus one of a choice of Layouts in the middle. A Layout is made on one or more Panes, each Pane can contain a Network Editor, Viewer, Panel, etc. See Pane and Bookmark. (2) Nodes in a network are arranged using Layout commands in the RMB menu.
Link Link Unlike a Wire that connects nodes in the same Operator Family, a Link is the dashed lines between nodes that represent other data flowing between nodes, like CHOP Exports, node paths in parameters, and expressions in parameters referencing CHOP channels, DAT tables and other nodes.
Link Reference A Link.
Lock Flag Lock Flag When an operator is locked, it does not cook and its output data remains frozen, even when the TouchDesigner session is saved to a .toe file and restarted.
Macro Macro A Tscript-only script that executes one or more scripting language commands. The F1 to F12 keys run macros. The F1 macro puts you in Perform Mode. See also Script, DAT and Python.
MAT MAT, Material An Operator Family that associates a shader with a SOP or Geometry Object for rendering textured and lit objects.
Menu Bar Menu Bar The bar at the top of the Designer Mode interface that contains menus, links, status messages and other controls.
MultiTouch MultiTouch, Multi-Touch Support in TouchDesigner for screens and input devices that support multiple-finger input.
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.
Network WYSIWID 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 Network Path Is the path to a Component or Operator. This path is displayed at the top of every Pane, showing which Component's network you are currently in.
Network Path 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.
Node Node 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.
Node Viewer Node Viewer The viewer found on each operator in a Network Editor pane. This viewer is turned on by clicking the Viewer Flag.
Node Viewer Viewer flag Each node has a viewer flag that turns on/off the node's viewer in the Node Viewer.
Object Object The component types that are used to render 3D scenes: Geometry Component contain the 3D shapes to render, plus Camera, Light, Ambient Light, Null, Bone, Handle and other component types.
OP Create Menu OP Create Menu The menu used to select and create a new operator or component. Can be opened by the + sign in the Pane Bar, by pressing the <Tab> key while in a Network Editor, or by clicking MMB or RMB on an operator's output connector.
OP Snippets Snippets OP Snippets is a set of numerous examples of TouchDesigner operators, which you access via the Help menu. These can be copied/pasted into your projects.
Operator OP, Operator 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.
Operator Operator Family The Operator Families are TOPs, CHOPs, SOPs, MATs (Materials), DATs (data operators) and Components (Panel Gadgets and Objects).

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 Expression Parameter Expression A parameter expression is a python expression that is in the expression field of a parameter.
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.
Parameters Dialog Parameters Dialog A floating dialog, pane type, or dialog in a Network Editor that displays one operator's parameters.
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.
Perform Mode Perform Mode Mode where the network editing window is not open, your performance interface window(s) is open and you are running your application as fast as possible. See Designer Mode.
Performance Monitor Performance Monitor The tool built-in to TouchDesigner that analyzes and displays what TouchDesigner is doing as it generates an image.
Pipe Pipe A way of moving data from one TouchDesigner process to another. Images are moved via Touch Out / In TOPs, channels are moved via Touch Out / In CHOPs and Pipe Out / In CHOPs. Data moves via TCP/IP or UDP.
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.
Popup Help Popup Help Help message that comes up when rolling the cursor over the interface, or clicking the ? help button on the corner of each operator's Parameters page.
Primitive Primitive A surface type in SOPs including polygon, curve (NURBS and Bezier), patch (NURBS and Bezier) and other shapes like sphere, tube, and metaball. Points and Primitives are part of the Geometry Detail, which is a part of a SOP.
Privacy Privacy Privacy of Components or .toe files is the protection of networks to enable using them but not accessing them internally.
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.
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 .pulse() 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 .pulse() function on a pulse-type parameter, for example op('speed1').par.resetpulse.pulse().

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.
