    New Features - Release Highlights
    New Operators
    • FreeD CHOP - New CHOP that creates channels from a stream of FreeD camera tracking data.
    • Lens Distort TOP - New TOP that distorts the input image to match the lens intrinsics provided. Applying this to a Render in TouchDesigner allows renders to align properly with live feeds from cameras.
      • Implemented inverse lens distortion shader (uses an approximation formula that doesn't include k3). Includes a menu to choose whether camera matrix values are normalized or in pixels allowing for easier workflow with openCV.
      • Added parameters to scale and position the distorted image within the frame.
    • Phaser CHOP - New CHOP for phase-staggered animations. Watch David's 2019 Montreal TouchDesigner Summit talk presenting some techniques possible with the Phaser CHOP.
    • Point Transform TOP - New TOP that treats the RGB channels as XYZ positions or vectors and performs a 3D transformations on those positions. Analogous to the Transform XYZ CHOP.
    • Spectrum TOP - New TOP that performs OpenCV's Discrete Fourier Transform (DFT) operation via CUDA (Windows only, requires Nvidia GPU).
    • Sprinkle SOP - New SOP that sprinkles points on a SOP surface or inside its volume.
    • JSON DAT - New DAT for parsing JSON and filtering outputs, which eliminates having to code scripts to parse and manipulate JSON, and keeps the data flow procedural.
     
    Streaming & Video
     
    Skeleton Tracking
    • wrnchAI CHOP - New CHOP which supports wrnchAI skeleton tracking for any camera or video stream input. (Windows only and requires Nvidia GPU)
    • RealSense CHOP - The RealSense CHOP has been overhauled to use the Cubemos skeleton tracking SDK. This works with the current librealsense API for RealSense to offer skeleton tracking to all the latest RealSense cameras. A separate Cubemos license is required, you can get a free 30-day trial to try it out here.
     
    Device Support

      • Added loadByteArray() to load compressed data stored in bytearrays.
      • Allow source to be 3 channels for copyNumpyArray().
      • Added copyCUDAMemory, allowing data to be loaded from CUDA.
    • Script OPs custom parameters can now be edited using the same Component Editor Dialog as components by dragging the Script OP onto the dialog’s ‘Path’ or right-clicking on the OP and selecting ‘Customize Operator…’.
     
    Web Connectivity
    • Web Render TOP - Added options to 'Enable Media Stream' which enables the mic and camera to be used by web pages. Also included an option to specify a 'User Cache Directory'.
    • Web Server DAT - Added 'Certificate Password' parameter to fix usage of password-protected certificates in secure servers.
    • Web Server DAT - Added Info DAT reporting to fetch any start-up errors.

    3D Viewer Camera Controls
    • 3D Viewer Camera Controls overhauled for pane Geometry Viewers and Object COMP and SOP node viewers.
      • 4 Camera Navigation Modes selectable from the right-click menu in the viewer.
      • For the first 3 modes the camera dolly now moves towards the cursor position rather then the center of the screen. Each of these modes differ in the way they set a pivot to tumble around.
      • The last mode, Camera Mode, moves and pivots from the perspective of the camera and is more similar to the movement possible using a real-world camera (ie pan, tilt, dolly, track, crane).
      • Scroll wheel now also works for dolly in addition to the previous MMB-drag.
      • New outline shader for selected geometry, no longer colors the entire object solid green or yellow.
      • 3D Spacemouse supported in all 3D viewers https://www.3dconnexion.com/ (Windows only, macOS work in progress)
     
    Drag-and-Drop
    • Drag-and-Drop overhaul - To create custom drag/drop systems for your control panels and UIs.
      • Use Python Drag/Drop Callbacks with all Panel Components for 'When Dragging This' or 'On Dropping Into' events.
      • When Dragging This callbacks include onDragStartGetItems(comp, info) → list of items to drag and onDragEnd(comp, info)
      • On Dropping Into callbacks include onHoverStartGetAccept(comp, info) → True if drag items are acceptable, onHoverEnd(comp, info), and onDropGetResults(comp, info) → Dict of results
      • For usage details and examples see this new documentation Drag-and-Drop
      • BACKWARDS COMPATIBILITY WARNING. This system has backwards compatibility issues with versions of prior to 2020.46450. Migration Guide here.
     
    Floating Licenses
    • Floating Cloud Licenses are a new option for licensing. These floating licenses allows any internet connected computer to access a pool of floating licenses on a single account.
    • Available in store now in the shopping cart's 'Select Product' list.
    • These licenses are great for:
      • Distributed Teams and Remote Working - Local computers can be licensed from a global pool of licenses available to any of your team, world-wide. A pool of numerous licenses on one account can be shared between global locations such as offices, studios, or installations, delivering the license to the team member on demand.
      • Lab Computers at Schools and Universities - Sometimes lab computers are wiped and/or do not have admin privileges to install a key. Using floating cloud licenses allows the system administrator to install the credentials onto lab computers as part of their disk image. This setup will automatically use licenses when TouchDesigner is in use and return them when TouchDesigner closes.
      • Running TouchDesigner on Cloud Platforms - A great usage case for floating cloud licenses is for running TouchDesigner and TouchPlayer on servers in the cloud. Often these virtual cloud servers do not have consistent system codes, or you may be spinning up instances dynamically and need a method to auto-key them. Dongle-based solutions usually don't work since it's rare that access to the hardware is possible for cloud servers.

    • Added missing parameter types to C++ SDK: appendOP, appendCOMP, appendMAT, appendPanelCOMP, appendHeader, appendMomentary, appendWH.
    • Each textport now uses its own local variables, which are also separate from parameter expression space.
    • Added 'Node Language' column in List mode to more easily weed out Tscript nodes.
    • Privacy - Text TOP / Field COMPs now work when inside protected components.

    Other Bug Fixes
    • Palette - Fixed issue with dragging components from user folders with unicode characters.
    • Custom Operators - Fixed crash that can occur if getInfoDATEntries() doesn't fill in some entries.
    • Custom Operators - Calls to the plugins are now wrapped in try/catch clauses to avoid crashing if there are bugs in the plugin code. Will emit a node error instead.
    • Matrix Class - BACKWARD COMPATIBILITY WARNING When building a Matrix from a Table DAT, fix the matrix being incorrectly transposed.
    • Par.section used in expressions now refreshes properly.
    • Par.enableExpr now propagated correctly through clones.
    • TOP point viewer now properly retains its camera position when adaptive homing is disabled.
    • Geometry viewer improvements for restoring camera positions in some cases that use adaptive homing.
    • Adding/removing Tags using Parameter Dialog now undoable.
    • Optimized Expressions - Added support for n.par['tx'] (the [] part).
    • Fixed User Shortcuts override files that were not working.
    • Fixed enableExpr not refreshing on certain dependencies.

    • Fixed dragging and dropping of CHOP channels onto parameters that were already exported onto.
    • Basic widgets fixed problems with font enumeration and Border Color fix to 2D slider.
    • Auto scrollbars turning off now layout properly first time.
    • Fixed erratic layout dealing with uninitialized scrollbar areas.
    • Fixed ranges when automatic horizontal and vertical scrollbars used.
    • Fixed auto scrollbars in children.
    • Fixed some odd behavior with drag drop.
    • Fixed bug that prevented dragging geometry in orthographic views (top, right, front, etc)
    • Fixed problems using the 's' and 'SPACE' shortcuts to temporarily switch between view and transform modes in the geometry viewer pane.
    • Fixed the orientation of the Top and Right cameras in all 3D geometry viewers
    • Fixed a number of crashes.
      • Loading crash when Time Component inside clone.
      • Fixed crash when updating 'inside' panel value which trigger cooks that cause the current UI to be deleted.
      • Crash when attaching input to Sequencer CHOP.
      • MacOS Movie File In and Movie File Out crashes that could occur.
      • Fixed a crash when trying to render some unicode newline characters.
      • Fixed crash on self deleting 'Help DAT' in panel.
      • Fixed crash that could occur on loading an empty file into a Table DAT.
      • Fixed crash with odd copy case in COMP.copy() method.

    SDK and API Updates
     
    Backward Compatibility
    • BACKWARD COMPATIBILITY RealSense - Removed support for the old Windows SDK and its tracking features. RealSense CHOP/RealSense TOP will now only support the cross platform librealsense API.
    • BACKWARD COMPATIBILITY - RealSense CHOP - Changed 'Image Positions' to 'World Positions' and have it return x, y, z channels converted from image coordinates to world using the camera intrinsics.
    • BACKWARD COMPATIBILITY - Screen Grab TOP - Capture area is now scaled to fit the output resolution rather than cropped when using GPU to GPU capture. Allows capture of windows that are larger than 1280x1280 with a Non-Commercial license.
    • BACKWARD COMPATIBILITY CHOP to TOP - Reworked Fit to Square layout. Auto-calculated image dimensions may no longer be the same as in previous versions.
    • BACKWARD COMPATIBILITY OpenVR CHOP - Left and Right Controller toggles have been removed, both controllers will always be output in that mode now.
    • BACKWARD COMPATIBILITY Circle SOP - Normals for the ZX orientation now point along the positive Y axis for consistency with other orientations and SOPs.
    • BACKWARD COMPATIBILITY WebSocket DAT - Removed onConnectionReady callback.
    • BACKWARD COMPATIBILITY Matrix Class - When building a Matrix from a Table DAT, fix the matrix being incorrectly transposed.
    • BACKWARD COMPATIBILITY- Par_Class.style now returns 'Object' instead of 'OBJ' in such cases, though Page_Class.appendOBJ is still functional.
    • BACKWARD COMPATIBILITY - WebclientDAT_Class.request data keyword will no longer implicitly add to query parameter list for non-postfield HTTP operations (eg. GET). For adding query parameters instead use the new 'pars' keyword.
    • BACKWARD COMPATIBILITY - Empty menu parameters now eval as ' ' instead of '0' and return a menuIndex of None instead of 0.
    • BACKWARD COMPATIBILITY - opinfo(), opinfop() Tscript expresions and opinfo command are deprecated.
    • BACKWARD COMPATIBILITY. Drag-and-Drop system has backwards compatibility issues with versions of experimental prior to 2020.46450. Migration Guide here.
    • BACKWARD COMPATIBILITY- TDAbleton - Clip data channels now include the clip number in their names.
