    Release Highlights

    OAK-D AI Sensors

    OAK-D cameras offer a range of high-resolution cameras with depth vision and on-chip machine learning. OAK-D can run computer vision tasks on-device and send the processed images or data to TouchDesigner on both Windows and macOS. For example, an OAK camera can compute human skeleton landmarks for a live RGB image and send both the landmarks and image to TouchDesigner. OAK is short for the OpenCV AI Kit, which originated through online crowd-funding. Luxonis has expanded the line of OAK hardware and also released several open-source libraries such as DepthAI that run on the OAK.

    The aim of integrating TouchDesigner with OAK cameras is to facilitate novel interactions with the rest of the TouchDesigner environment while providing low-latency, high throughput performance with the OAK hardware. If you think a pure Python example that doesn't involve TouchDesigner is running faster than one which does, please let us know. For example, we aim for the frames-per-second of an OAK's RGB camera received in TouchDesigner to be at least as fast as what you would receive in pure Python with DepthAI and OpenCV.

    Three new OAK-D operators work together to implement the OAK functionality: The OAK Device CHOP is the main interface to the camera devices. The OAK Select CHOP extracts channel and dictionary data from the camera results of a OAK Device CHOP. The OAK Select TOP extracts processed images from the camera. Each DepthAI model running on each camera will have one OAK Device CHOP plus one or more of the OAK Select OPs.

     

    Machine Learning

    The following features utilize machine learning models in their operation and are only supported on Windows OS. If you do not have the devices required to use them, you can save bandwidth and time by using the new Web Installer which does not include the models in the initial download, allowing you to select only the features you need.

    • Body Track CHOP - This new CHOP uses Nvidia Maxine AR SDK to perform body pose estimation on any video or camera input. It can track bounding boxes and 34 key points of one or more human bodies, with optional joint angles, in 2D or 3D.
    • ZED - Major overhaul including an SDK update and the addition of body tracking support in the ZED CHOP and a 'Neural' depth camera mode in the ZED TOP.
    • Orbbec - Body tracking in the Kinect Azure CHOP now also works with Orbbec Kinect-compatible-cameras (Femto Mega, Femto Bolt). Furthermore, general support for color/depth/pointcloud has been added for a wider range of Orbbec cameras via the Orbbec TOP.
    • Nvidia Upscaler TOP - This new TOP uses Nvidia Maxine Video Effects SDK to upscale the resolution of an input video. The Upscale mode is faster and offers a 'Strength' parameter. The Super Resolution mode is higher quality and doesn't offer a Strength parameter, but it does have an optional 'Artifact Reduction' toggle.

     

    Timecode Tools

    Numerous Timecode tools have been woven into TouchDesigner. A new Timecode CHOP can create and manage SMTPE timecode and a large selection of OPs in TouchDesigner that deal with time have been updated to be driven by timecode or include a timecode member so they can be managed effectively. For a full list of these operators, refer to the Timecode page.

    • Timecode CHOP - A new CHOP for managing Timecode
      • Added custom length parameters and extra countdown field to Info DAT.
      • Added countdown output channels.
      • Check out the new OP Snippets for this operator.
    • Timeline CHOP - Added a new parameter to drive timeline time with a timecode object.
    • LTC Out CHOP - Added a parameter to drive the LTC Out timecode with a Timecode Object/CHOP/DAT.
    • Timer CHOP - Added option in the 'Time Control' parameter to drive the Timer CHOP directly with timecode.
    • Timecode Class - A new class to access timecode features via python throughout TouchDesigner.
    • Many operators that can use timecode now have new timecode members to access their timecode directly via python.

     

    Apple ProRes

    Full support for Apple ProRes in TouchDesigner on both Windows and macOS.

    • Movie File In TOP - Support for ProRes decoding. Uses hardware decoding on macOS when available.
    • Movie File Out TOP - Support for ProRes encoding. Uses hardware encoding on macOS. TouchDesigner's ProRes encoding has been certified by Apple for correct implementation of the format.
    • ProRes is equally supported across TouchDesigner, TouchPlayer and TouchEngine.

     

    Laser Control

    • Laser Device CHOP - The Laser Device CHOP can send laser points to supported laser devices: EtherDream, Helios, and ShowNET. ShowNET support comes to TouchDesigner for the first time! The devices can be connected to a laser using an ILDA cable, except in the case of ShowNET when an onboard DAC is used. Applications of the Laser Device CHOP include displaying computer-generated shape animations or other special effects of a light show. The Laser Device CHOP replaces the deprecated EtherDream CHOP and Helios DAC CHOP.
    • Laser CHOP - Added look-up CHOP for vertex hold min/max angles and added 'Blank State Channel' for help with debugging.

     

    New Operators

    Hardware Device Operators

    • MoSys CHOP / MoSys TOP - The MoSys CHOP receives data from a MoSys camera tracking system. The channels can be used to control a virtual camera and to implement lens distortion via the MoSys TOP as part of a virtual production system.
    • Orbbec TOP - Support for color, depth, and pointcloud capture has been added for a wide range of Orbbec cameras. Furthermore Kinect-compatible Orbbec camera such as the Femto Mega and Femto Bolt models also support Kinect body tracking through the Kinect Azure CHOP.
    • SICK TOP - This new TOP can be used to retrieve point cloud data from a SICK LIDAR sensor. Sensor results are packed into a floating point texture where each pixel represents one point of data and each color channel stores one field such as x, y or z position. The TOP utilizes the 'sick_scan_xd' SDK and supported sensors are listed on the project's GitHub page.
    • Audio Devices DAT / Video Devices DAT - Two new DATs which list all input and output audio/video devices. Callbacks are included to create actions when devices are added or removed.

    Micellaneous Operators

    • Bloom TOP - The Bloom TOP creates an intensity gain and glow effect around brighter parts of the image.
    • GLSL COMP - The new GLSL COMP uses GLSL shaders to render an image in a panel directly to the screen. It is useful for rendering pixel accurate UIs as the resolution will automatically adapt to the DPI scaling of the screen it is displayed on.

     

    Engine COMP Overhaul

    • Engine COMP - New features and improvements.
      • Enabled OP Viewer parameter on Common parameter page to show a selected viewer.
      • Added 'Asset Paths' parameter to make relative paths based on the Project .toe file or the External .tox file.
      • Added TouchEngine process parameters on the Advanced parameter page. This allows you to quit or launch the process independently from loading your component.
      • Added 'On Engine COMP Create' parameter which determines what happens when a .tox is loaded (also affects when a new Engine COMP is created through copy & paste).
      • Errors on the loaded component are now reported in the pop-up info text via middle-mouse button .
      • Added a new onError() callback to the Callback DAT.
      • Allow use of user selected operator colors (use color palette to set).
    • New Init Start parameter page modelled after Init Start on the Timer CHOP including a similar set of core control parameters.
      • Added “Ready when” parameter to specify when the transition to Ready state happens.
      • Added onInitialize() callback.
      • Added 'Go To Done' parameter and 'On Done' parameter to determine behavior. This include extras like an onDone() callback, a "done" channel, and "goToDone()" Python command similar to a Timer CHOP.
      • Added a 'Pre-Roll' parameter that will run the component for the specified amount of time before setting it to Initialized state.
    • Added a docked Info CHOP
      • More channels added in 'General' Info Type.
      • Added “Initialize Start” Info Type group of channels reporting on the Status of the Init Start features mentioned above.
      • Added 'TouchEngine Status' Info Type group of channels for process and component state to better understand the TouchEngine process lifetime.
      • Renamed Engine Perform to 'TouchEngine Perform'.
      • Added Info CHOP channels output_cook_abs_frame, engine_absolute_frame, engine_absolute_seconds, and initialize_fail.
    • Added a docked Info DAT
      • Added “engine_pid” to Info DAT.

     

    Lightweight Web Installer for Windows

    The best option for installing TouchDesigner on Windows is our new lightweight web installer. This installer packages the core elements of TouchDesigner into a significantly smaller download. During installation you can select the features of TouchDesigner you require and it will download them on-the-fly. If you don't have hardware like a Kinect Azure camera, ZED camera, or Nvidia GPU on your system, save time and bandwidth by skipping these items. With the addition of more devices, SDKs, and features using machine learning models, the full installer is now over 2.4GB and will continue to grow. The web installer is a great option for anyone working with a reliable internet connection. The download size is smaller, the installation goes more quickly, and TouchDesigner uses less space on your system. Only install what you need!

    Add additional features after the initial installation by going to Settings > Add or Remove Programs and locating your TouchDesigner application. Then select Modify from the options menu and the Modify installation dialog will open allowing you to select the features you'd like to add.

    We will always continue to maintain a full installer for those who need everything or need to install TouchDesigner on machines where there is no internet connection.

    For info on how to use the web installer see Install_TouchDesigner#Dealing_with_Installer_Components_of_the_Web_Installer

     

    More New Features

    Python 3.11

     

    Custom Sequential Parameters

    Sequential Parameters are sets of parameters that can be dynamically repeated multiple times, grown and shrunk using the +/- buttons in the parameter dialog. We have revamped their naming and added support to custom parameters so users can now define their own sequential parameters. These can defined directly with python or through the Component Editor Dialog.

    All sequential parameter sequences (both built-in and custom) now start with a new sequence parameter. The name of this sequence parameter defines the prefix of all the following parameters in that sequence block.

    The new naming format is: <sequence name><block index><parName>.

    Every sequence now has a "sequence name" which is added as a prefix to every parameter that is part of the sequence. This is followed by a "block index", which is the index of the block (set of associated parameters) within the sequence.

    For example, the name/value pars in a Constant CHOP used to be called name0/value0, name1/value1, etc. The new names are: const0name/const0value, const1name/const1value etc. Other notable examples are extensions (sequence name "ext") and internal operators (sequence name "iop") TouchDesigner will attempt to understand the old names as aliases, but there may be backwards compatibility issues in some cases.

    • TouchEngine and Engine COMP also fully support sequential parameters now.
      • TouchEngine - Added a the new sequence parameter type, added a function to change sequence block count.
      • TouchEngine - For hosts using older library versions, expose sequences as a series of regular parameters.
      • Engine COMP - Correctly display, edit and update parameter sequences, including changes to block count.

     

    Working with External Files

    • New parameters on the Common page of all Components offer better control of managing external file locations and paths.
    • New parameter 'Relative File Path Behavior' allows you to use relative paths that are local to the Project (.toe file) or to the location of the External COMP (.tox file).
    • We invite you to read our article introducing some changes and new features.

     

    macOS Hardware Decoding

    • Movie File In TOP and Video Stream In TOP now supports hardware decoding when available (this is depends on the Mac's hardware). To enable on the Movie File In TOP, turn on the 'Hardware Decode' parameter toggle on the Tune page.
      • Supported codecs vary by hardware, potentially works for Apple ProRes, H.264, HEVC (H.265), P-JPEG, VP9, AV1.
      • When possible it does direct-to-texture decode - image memory is always on the GPU.

     

    Nvidia 40-series GPU Improved Support

    • The machine learning models for Nvidia operators using Maxine SDKs have been updated to include models for the 40-series Geforce and Professional A-series Ada generation GPUs.

    • Render TOP - The 'Image Output' feature has been reworked. Multiple can now be created, with custom names, array sizes and formats. This is found on the new 'Image' page.
    • Spectrum TOP - Revamped the Spectrum TOP to use Vulkan via the VkFFT library, deprecating the CUDA and OpenCV usage. It results in much faster performance and cross platform support for both Windows and macOS.
    • Text COMP / Text TOP - New options for selecting fonts via a new 'Typeface' parameter instead of the previous 'Bold' and 'Italics' parameters.

    CHOP Features

    • Audio Device In CHOP - Added 'Rate Mode' parameter for ASIO devices that can pull the sample rate from the device rather than manually override it.
    • Audio VST CHOP - Added support for custom bus layouts and new parameters for controlling the VST plugin's playhead.

      • Active toggle expanded to: Never / Always / While Running / While Playing. 'While Playing' only cooks if any timers are active and 'Play' is enabled.
      • New 'Defer Parm Changes' parameter controls whether or not parameter changes take affect immediately or after the next init/start cycle.
    • Transform CHOP - Added 'Xform Matrix/CHOP/DAT' parameter to apply a matrix transform directly.
    • Trigger CHOP - Added menu option 'Update once per Cycle' to update trigger shape parameters only once each cycle.

    DAT Features

    • Insert DAT - You can now add rows and cols via cell expressions and added a new 'Replace if Duplicate Name' toggle to replace existing column/row names if new ones have the same name.
    • Keyboard In DAT - Overhaul to how characters are handled with the goal to improve international language support and offer a more consistent interface with keyboard input.
      • BACKWARDS COMPATIBILITY ISSUE - The 'key' column will no longer return special characters such as !@#$%^&*(). These will now be 1234567890 for better consistency with other shortcut workflows.
      • New optional 'web_codes' column, which matches the key code names that Chromium expects.
      • Reworked callback to take a namedtuple, add 'webCode' as a new value.

     

    New Python

    Python Version 3.11

    opex() Method Instead of op()

    • OP Class / td Module - New opex() method that works identically to op(), except it will raise an exception if it fails to find the node instead of returning None as op() does. This is the new recommended way to get nodes in parameter expressions, as the error will be more useful than 'NoneType has no attribute 'par', that is often seen when using op(), for example.

    Reset Parameters via Python

    reset() -> bool - Resets the associated parameters to its default state, returns true if anything was changed.

    op('geo1').par.tx.reset() op('geo1').parGroup.t.reset() op('geo1').pages[0].resetPars() op('player').customPages['Setup'].resetPars() op('player').resetPars(includeBuiltin=False) # only reset custom

    Default Parameters via Python

    • Par Class / ParGroup Class.defaultBindExpr .defaultExpr - Get or set the default bind expression on custom parameters.

    n.par.Float1.defaultBindExpr = 'me.par.Float2' n.par.Float1.defaultExpr = 'me.time.frame'

    • Par Class / ParGroup Class.defaultMode - For custom parameters get or set the default evaluation mode. Resetting the parameter sets it to .defaultExpr expression, so using the previous example n.par.Float1.defaultExpr = 'me.time.frame', then the expression would be set to me.time.frame.

    n.par.Float1.defaultMode = ParMode.EXPRESSION

    • Project Class.quit() - Added exitCode keyword argument, to manually specify an exit code on quitting.

    BACKWARD COMPATIBILITY sequence[3] sequence.blocks[6] etc now returns a block, whose elements are now ParGroup objects, not Par objects.

    • Sequence Class - New par and parGroup members which return a list (one from each block) or None.

    For example:

    n.seq.Info.parGroup.T # entire list n.seq.Info.parGroup.T[3] # ParGroup from 4th block. n.seq.Info.parGroup['T'] # None if not found, else entire list

    Can be accessed via:

    • Sequence.blocks
    • Sequence[index]
    • Iterating through Sequence

    Block members include .index .owner .sequence .par .parGroup

    For example:

    for p in Block (iterating) len(Block) (number of pars) Block[index] (each par)

    • Timecode Class improvements
      • Timecode Class.cycle - A new member for getting/setting whether the timecode will cycle once it reaches its max (default value: True)

      • TOP Class.pixelFormat - New member that returns the pixel format as a string.
    • scriptTOP Class - copyCUDAMemory() now supports a 'stream' keyword argument. Use this to make use of a cudaStream_t/CUstream stream to do the work on.
    • run function. The first argument can now be an optional function instead of a string. This can be easier to work with rather than constructing an executable line of code with embedded quotes.

    run( lambda: print('A') ) run( lambda x: print(x), 'B' ) run( print, 'C', 'D', 'E')

      • run(func) now accepts keywords. ie. run( myfunc, 'C', a=1, stop=True)
    • tdu_Module.match - BACKWARDS COMPATIBILITY ISSUE - Now supports space separated patterns and single ^ terms properly. tdu.match interprets spaces in the pattern argument as separators.

    eg:

    tdu.match( "^foo", ["bar"] ) # ["bar"] tdu.match( "* foo", ["bar"] ) # ["bar"]

    • TDJSON - BACKWARD COMPATIBILITY ISSUE Including 'eval' in extraAttrs argument list will now create a new "eval" entry in the JSON instead of replacing the value in "val".
    • Parameter members .expr, .bindExpr, .defaultExpr, .defaultBindExpr assigned to None in scripts will now be empty string instead of the string 'None'. BACKWARDS COMPATIBILITY ISSUE

    • Palette:kinectPointcloud - v1.0.2 - Updated to use the latest pointRender and cameraViewport components.

     

    • Palette:logger - v2.2.5 - A new palette component wrapping around the Python Logging Library and interface to add additional Loggers easily in your TouchDesigner projects.
      • The logger COMP follows the propagation rules of the python library.
      • A Stream Handler was added to handle Textport log items. Therefore, when interacting with the logger COMP or the logger object directly, it will in most cases have an impact on both handlers (if used simultaneously). For example, when the setting changed is impacting the Logger object rather than an handler, such as the log level, or propagation. Status Bar is not using an handler.

     

    • Palette:particlesGpu

    Licensing

    • On Windows, TouchDesigner's License System Codes are now generated differently to reduce the chance of a system code change when applying Windows Updates. Old keys will work in this 2023.10k branch, however, new keys created in this 2023.10k branch will not work with older versions of TouchDesigner. We also have release an update to 2022.20k branch so any builds released after July 10 2023 will also work with the new keys created in this 2023 version. In summary - If you want to use 2022 and 2023 versions with the same key, either a) create your key using 2022 builds, or b) use a 2022 build released after July 10 2023.
    • Errors are now provided when Floating Cloud and Dongle licenses are expired for the current build.
    • Floating Cloud licenses won't be consumed anymore if a better Dongle license is present on the system. Furthermore, floating cloud or dongle licenses won't be used if a higher level local license is installed through the Key Manager Dialog.

     

    Panel Layout Optimization

    • Lots of work was done to speed up internal panel layout code resulting in many control panels performing significantly faster. If you discover regressions or control panels that are still extremely slow, please contact us via the bugs forum.

    Backward Compatibility

    Change for keys on Windows systems

    • TouchDesigner's License System Codes are now generated differently to reduce the chance of a system code change when applying Windows Updates. Old keys will work in this 2023.10k branch, however, new keys created in this 2023.10k branch will not work with older versions of TouchDesigner.
    • We have released an update to 2022.20k branch so any builds released after July 10 2023 will also work with the new keys created in this 2023 version. In summary - If you want to use 2022 and 2023 versions with the same key, either a) create your key using 2022 builds, or b) use a 2022 build released after July 10 2023 (yet to be released).

     

    File Compatibility

    ⚠️ Project .toe files saved in 2023 Official builds can not be loaded back into previous versions of TouchDesigner such as 2022 or 2021 builds.

     

    Backward Compatibility Changes

    We try to make upgrading to new TouchDesigner branches as painless as possible, but sometimes changes are made that are not compatible with the feature set in older builds. These are difficult decisions and we do not take them lightly, but we move forward with such changes when it is clear that they will benefit the TouchDesigner platform in the long term.

    • BACKWARD COMPATIBILITY ISSUE - tdu.match interprets spaces in the pattern argument as separators.
    • BACKWARD COMPATIBILITY ISSUE - The Keyboard In DAT's 'key' column will no longer return special characters such as !@#$%^&*(). These will now be 1234567890 for better consistency with other shortcut workflows.
    • BACKWARD COMPATIBILITY ISSUE - Parameter expressions assigned to None in scripts will now be empty string instead of the string 'None'.
    • BACKWARD COMPATIBILITY ISSUE - When Python parameter expression is blank, return None, not empty string.
    • BACKWARD COMPATIBILITY ISSUE - Panel.interactMouse/interactTouch will respect a panel's 'Enable' parameter toggle.
    • BACKWARD COMPATIBILITY ISSUE- Optical Flow TOP - 'Cost Output' values are now normalized to 0-1, instead of 0-255.
    • BACKWARD COMPATIBILITY ISSUE - TDJSON - Including 'eval' in extraAttrs argument list will now create a new "eval" entry in the JSON instead of replacing the value in "val".
    • BACKWARD COMPATIBILITY ISSUE - Point File In TOP / Point File Select TOP - Altered how the output texture size is determined based on the number of points. Might result in different texture sizes than previous versions.
    • BACKWARD COMPATIBILITY ISSUE - Sequence Class.blocks - This now returns a list of SequenceBlock Class not list of tuples of Pars. sequence[3] sequence.blocks[6] etc now returns a block, whose elements are now ParGroup objects, not Par objects.
    • BACKWARD COMPATIBILITY ISSUE - Several built-in parameters have been renamed for consistency, starting with index 0, etc. Older files will load correctly and get updated when saved, but note that files saved in 2023.10k builds will cause issues if loaded into any previous builds.
    • BACKWARD COMPATIBILITY ISSUE - Texture SOP - Fixed UV stretching and shearing of 'Face' type mapping. This changes the behaviour of 'Face' type option.
    • BACKWARD COMPATIBILITY ISSUE - Parameter order gets overridden when changing a Parameter's page member.

     

    Known Issues

    Please report all issues to the Bugs Forum, remember to include build number.

    • Bloom TOP - 'Bloom Alpha' toggle is not calculating alpha correctly, look for an update soon.
    • Body Track CHOP - Can sometimes crash if parameters are manipulated too quickly.
