    • Use unicode almost anywhere you can type a string
    • File names and file paths can now contain unicode characters
    • DATs can now accept unicode characters directly
    • Text TOP and Text SOP accept unicode characters directly
    • Parameters can now contain unicode characters
    • Python can use unicode characters where supported
    • Some parts of TouchDesigner must still use standard alphanumberic characters, such as Operator names, Channel names, Custom Parameters, Custom Attributes.

Rigid-Body Dynamics

  • Physics - A new group of Dynamics Components now support hard-body physics simulations using Bullet Physics Library.
    • Bullet Solver COMP - Acts as the physics simulation solver.
    • Actor COMP - Holds geometry that is acted upon by the physics simulation.
    • Force COMP - Applies forces to Actor COMPs that specify them.
    • Impulse Force COMP - Applies impulse forces to Actor COMPs, which are forces that happen in an instant.
    • Constraint COMP - Constrains Actor COMPs together in 3 ways i) Point To Point ii) Hinge iii) Slider.
    • Bullet Solver CHOP - Extracts information from a Bullet Solver COMP or Actor COMP as channels that can be manipulated in CHOPs and then fed back into the simulation using the Bullet Solver COMP's 'Feedback CHOP' parameter.

FBX and USD Support

  • FBX COMP - New Component that loads FBX files as a network.
    • Allows for non-destructive updating of FBX assets while keeping network customizations.
    • No longer converts to intermediate .tog geometry format.
    • Support for lights, cameras, groups, merging geometry
    • Supports Direct to GPU
    • Separate parameter page for embedded animation control

Custom Operators and C++

  • Custom OPs - Now C++ OPs you create have a new API allowing them to act like regular built-in operators. This includes giving them their own custom names and having them available in the OP Create Dialog.
  • C++ DAT - The DAT family finally gets a C++ operator to create DAT Custom OPs as well.
  • CPlusPlus OPs and Custom OPs now work with Non-Commercial licenses, they no longer require a Commercial or Pro license.

User Interface Toolkit

  • Widgets - A new set of UI components for building control panels, performance interfaces, applications and systems. Designed to be modular and updatable, this new architecture is fully customizable and extendible and will be TouchDesigner's primary UI toolkit going forward. Widgets use python under the hood and the old tscript-based TUIK has been removed.
  • This first release of Basic Widgets can be found in the Palette under UI > Basic Widgets. In the future there will also be a more advanced widget set for system builders, but we are looking for feedback on Basic Widgets first.
  • Widget COMP - New Panel COMP that will be a base for the upcoming Widget UI system. Work in progress, stay tuned for updates.

COMPs[edit]

3D Objects[edit]
  • Camera COMP - Added Quad Reprojection support. This allows an arbitrary section of a render, as defined by 4 points from a SOP, to be treated as the projection plane. The contents of the quad are reprojected to fill the final output view as part of the render, resulting in a full resolution render for that sub-region of the original render.
  • Light COMP - Added 'Projection Map Type' parameter that allows selecting a new 'Point (Equirectangular)' projection type. This will project an equirectangular texture out in all directions from the light's position.

      • Created internal preset values DAT inspector.
      • Added functionality for updating all presets in all banks when a parameter is added, removed or renamed on the target component. A confirm update dialog is created when a change is recognized. Also a pulse button has been added to the Setup page to manually update all presets with new or changed parameters. This is useful if a default value (other than the TD default value for the parameter type) for the new parameter for all the updated presets is wanted to be set. The workflow is as follows:
      • Added new parameter(s)
      • When confirm dialog opens and asks to update all presets, press cancel
      • Set the value of the parameter
      • Press Update All Presets button on Setup page and confirm.
      • Now all previously stored presets will have the desired value(s) set in the new parameters.

disable both recall and blend of parameters with expressions by default on store of preset with expression in parameter filter target components "presets parameters" in settings list so they are not viewable or editable.

  • Palette:probe component enhancements.
    • Cook times of nodes that haven't cooked recently are better-reported.
    • Can use mouse wheel to zoom large networks (but not go between networks yet).
  • Palette:camSchnappr bug fixes and improvements.
    • Autoblend fixed.
    • Autoblend can now be shown in preview output whereas previously the mask was not applied to this output.
    • Added additional parameters for the Autoblend feature to control the blend curve via RGB gamma/luminance based on Paul Bourke's Edge Blending article from http://paulbourke.net/miscellaneous/edgeblend/

Backwards Compatibility[edit]

  • BACKWARDS COMPATIBILITY WARNING - 'Use Startup File' .toe file preferences need to be reset.
  • BACKWARDS COMPAITIBLITY WARNING - Evaluate DAT - The behavior of 'Convert Backslash Characters' has been streamlined, and only affects \\ \t \n and \r sequences. Furthermore, it will not strip quotes as it did previously.
  • BACKWARDS COMPATIBILITY ISSUE - Lag CHOP now uses the correct units for acceleration clamping.
  • BACKWARDS COMPATIBILITY ISSUE - GLSL TOP has replaced the binding/size parameters on the Atomic Counters page with a uniform name parameter.
  • BACKWARDS COMPATIBILITY WARNING - Par.cloneImmune renamed to Par.styleCloneImmune, update any scripts that may have relied on this.
  • BACKWARDS COMPATIBILITY WARNING - For CPlusPlus nodes, matrices are now returned in column major (vector on the right) convention to be more consistent with other code such as GLSL and tdu.Matrix classes.
  • BACKWARDS COMPATIBILITY WARNING * - Actor COMP moved Perform Contact Test toggle to Bullet Solver COMP.
  • BACKWARDS COMPATIBILITY WARNING * - Bullet Solver COMP / Actor COMP moved 'Callbacks DAT' parameter and docked DAT from Actor COMP to Bullet Solver COMP.
  • BACKWARDS COMPABITILITY WARNING - GLSL TOP, GLSL MAT - GLSL 1.20 has be deprecated on Windows (never been supported on macOS). Please upgrade GLSL shaders to 3.30 or later for compatibility with future release branches.
  • BACKWARDS COMPABITILITY WARNING - $TOUCH_START_COMMAND has been removed.
  • BACKWARDS COMPABITILITY WARNING - DATs named /start and /stream/start will not longer execute on file start. Use the Execute DAT instead.

An Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.

An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.

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.

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.

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.

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.

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 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.

Any floating window that is not a Pane or Viewer.

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.

TouchDesigner User Interface Kit - A collection of User Interface components.

Binding is a Parameter Mode that ties two or more parameters together, where changing the value of any one of the bound parameters changes value of all the bound parameters. The actual value is stored in one of bound parameters, called the bind master parameter.

An Operator Family that associates a shader with a SOP or Geometry Object for rendering textured and lit objects.

An Operator Family that associates a shader with a SOP or Geometry Object for rendering textured and lit objects.

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.

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

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.

A custom interactive control panel built within TouchDesigner. Panels are created using Panel Components whose look is created entirely with TOPs.

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.

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.

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.

The connection of an output of one node to the input of another node in a network. In contrast, see Link.

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

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.

A form of DATs (Data Operators) that is structured as rows and columns of text strings.

A built-in panel in TouchDesigner that contains a library of components and media that can be dragged-dropped into a TouchDesigner network.

TouchDesigner Component file, the file type used to save a Component from TouchDesigner.

Strictly refers to a window in Microsoft Windows. User-created windows are made with Panels inside Window Components, aside from the TouchDesigner editor window and its dialogs.

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.

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.

TOuch Environment file, the file type used by TouchDesigner to save your project.

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.

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

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.

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'.

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 custom interactive control panel built within TouchDesigner. Panels are created using Panel Components whose look is created entirely with TOPs.

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".
