2021 Initial Release
- 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.

- OpenCV - Updated to OpenCV 4.5.1
- Now TouchDesigner ships with the full OpenCV 4.5.1 toolkit
- Includes CUDA and the opencv_contrib modules (except for a few things that can't be included due to licensing). The extra modules give you access to functionality not packaged with the default OpenCV distribution. Examples of modules include: Aruco Marker Detection, 3D Object Recognition and Pose Estimation, Custom Calibration Patterns, Structured Light as well as various CUDA accelerated libraries. See full list OpenCV Modules.
- libs and headers used for OpenCV are now available in the
Samples/CPlusPlus/3rdPartyfolder for easy use of OpenCV with C++ and Custom Operators.
- Custom Operators - Parameter labels, page names, and string defaults should now properly support UTF-8.
- Script TOP - Additions for loading data.
- Added loadByteArray() to load compressed data stored in bytearrays.
- Allow source to be 3 channels for copyNumpyArray().
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 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.
- WebSocket DAT - Added callback function
onConnectionReady()called after onConnection, after connection has been upgraded.
- Text TOP - Added Slug support which is a high quality GPU-based scalable font rendering library. This is available by setting 'Display Method' = Scalable. This supports .ttf and .ttc font files or any installed font on the system.
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 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
list of items to dragand
- On Dropping Into callbacks include
True if drag items are acceptable,
onHoverEnd(comp, info), and
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 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.
Other Noteworthy New Additions
- Bullet Solver COMP - Added impact flag to collisions structure of onCollision() callback. The flag is True when the collision is at the point of impact.
