Official Build - 2018.20000 Series[edit]

New Features[edit]

Major New Additions[edit]

  • This version has substantial speed optimizations. Many of the speedups focus on using python expressions in parameters, and significant improvements to startup and project launch time have been made.
    • new Optimized Python Expressions will speed up commonly-used python expressions in parameters.
    • Caching expression results so they don’t need to recalculate. If a node needs to cook, only the parameters that *may* have changed will be re-evaluated.
    • Optimized the startup and launch process.
    • across-the-board speed improvement of TouchDesigner by between 10% and 25%.
    • Perform CHOP has new parameters to monitor how many expressions are optimizes and cached.
  • Dongle-based Component Privacy - Support for CodeMeter dongles to add Privacy to components and license their use.
    • Developers can now create CodeMeter dongles that will license the component to run (cook). These dongles do not give access to the networks inside, they just allow them to run on any licensed TouchDesigner or TouchPlayer.
    • A 'Developer Dongle' is used to make a component private and continues to give developer access to the networks inside the component.
    • Managing privacy with a Developer Dongle can be accessed through python or the Privacy Dialog (right-click on component and select 'Privacy...').
    • Setting up Developer Dongles is a service provided by CodeMeter and handled between the Developer and CodeMeter.
    • A Developer Dongle requires a TouchDesigner Pro license but no additional fees charged by Derivative.
    • Contact us for further details about Developer Dongles.
  • Dongle Floating Licenses - Multiple licenses can be loaded onto a dongle and then distributed to other computers on the network when TouchDesigner is launched.

  • tdu.remap(inputVal, fromMin, fromMax, toMin, toMax) -> double - Returns the input value remapped from the first range (fromMin/Max) to the second range (toMin/Max).
  • tdu.printErrors() has been removed, and replaced with op.errors(recurse=True)
  • tdu.printStack() is replaced with new print(project.pythonStack())
  • ext.parentshortcut is deprecated: Do not use this form any more. Use parent.parentshortcut.
  • tdu.split() added - Returns a list from a space separated string, allowing quote delimiters.

string: any Python object... will be evaluated as str(string), so parameters will work. eval: if True, convert any valid Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.

Examples:

  split('1 2.3 None fred "one '2'" "[1,2]"')

yields ['1', '2.3', 'None', 'fred', "one '2'", '[1, 2]']

  split('1 2.3 None fred "one '2'" "[1,2]"', True)

yields [1, 2.3, None, 'fred', "one '2'", [1, 2]]


New Palette[edit]

A pulse button will spit out movieEngine, a UI-less version that runs faster and can be embedded in other tools. External control has been revamped to allow a specific CHOP and channel to drive its timer, and allow for the channel to be expressed in seconds, frame or fraction.
  • Updated Tools > multiMix - Fixed bug with shader compilation on macOS.
  • Updated Tools > webBrowser - Fix to allow selecting, copying, and pasting text.
  • cornerPinSOP added to the Tools folder.

Any floating window that is not a Pane or Viewer.

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.

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 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.

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.

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.

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.

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.

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.

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.

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

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.

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

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.

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.

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

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.

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

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

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.

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

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

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.

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

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.

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.

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".
