Build 2019.30550 - Aug 17, 2019
- Python 3.7.2 is now the built-in version of python. Backward Compatibility warning, see below.
- Engine COMP - This component will run a .tox file in a separate process using TouchEngine. *Work in progress*
- Instancing with TOPs - Keep data on the GPU.
- On the Geometry COMP you can provide it with a TOP and it will render an instance for every pixel in the TOP. For example, floating point red, green, blue channels can be assigned to the instances' X Y and Z positions.
- In addition, you are no longer limited to one OP for specifying instancing data. The Instancing pages have been expanded so you can specify TOPs, CHOPs, SOPs, or DATs for every instance attribute interchangably. For example, position from a TOP and color from a CHOP.
- Point Clouds and general data with TOPs - Working with more data types on the GPU.
- Point File In TOP - .
plyfiles (Windows only). It will create a square multi-RGBA buffer with pixel format 32-bit floats. Generally it can be set up as one pixel for each point, and the pixels that are unused contain NAN (a special value called Not-A-Number).
- The operator's pop-up info shows the number of points and channels.
- An Info DAT attached shows the channel names in the file. The first 4 channels are put into RGBA (buffer 1), the next 4 channels are in buffer 2, etc
- Buffer Select TOP - Formally known as the Render Select TOP, this TOP is now more general-purpose and can also select buffers from a Point File In TOP if multiple buffers exist.
- TOP Viewer modes have been extended.
- 'Normalized Split' displays each channel separately as a normalized grayscale image with min and max values overlaid.
- 'View as Points' will visualize the data in a 3D Viewer like in SOPs, assuming the RGB channels contain XYZ point data.
- Point File In TOP - .
- Math TOP - Ranges can now be changed on individual color channels.
- Bind CHOP - Use CHOP channels for binding with parameters.
- Allows for multiple inputs (like old Override CHOP) or the bound parameter to update a channel's value.
- Includes a 'Callbacks DAT' for querying where the change was initiated and then taking further actions via python script.
- 'Channel Pickup' parameter doesn't change the value of that parameter until the input value crosses the current value.
- Binding - Binding to DAT text or table cells is now supported.
- Function TOP - New TOP allowing mathematical functions to be done on pixels, similar to the Function CHOP.
- CHOP to TOP - A new option to wrap long channel data into multiple rows of pixels when the channel's length exceeds the GPU's maximum texture width.
- Video Device In TOP / Video Device Out TOP - Upgraded to Blackmagic SDK version 11.
- Video Device In TOP - Added support for bandwidth and camera bit depth controls for Ximea cameras.
- Video Device In TOP - Added support for using the HDMI input from AJA io4K devices.
- Video Device Out TOP - Added support for Fill + Key pairs for AJA devices.
- Audio Movie CHOP - Added an option for switching audio tracks when movie files contain multiple tracks.
- Keyboard In CHOP - Keys are now defined in a space or comma separated list rather than as neighbouring keys on the keyboard. Old files are automatically updated to the new system when they load (only works for constant parameters).
- Added shift key support to the 'Modifier Key' parameter menu.
- Added 'Panels' parameter so events are only triggered when the given panel has focus.
- Mouse In CHOP - Added 'Panels' parameter so events are only triggered when the given panel has focus.

- LTC In CHOP / LTC Out CHOP - Improved to support higher frame rates and more.
- LTC CHOPs now work for higher frame rates.
- LTC In will now adjust the frame value based on the value in the User 1 channel.
field1is now automatically used for frame rates over 30.
- Added an option for LTC In to display the number of 'Total Frames'.
- Timeline CHOP - Added options for 'Second', 'Absolute Frame', and 'Absolute Second'.
- Hold CHOP - Added 'Hold per Sample' parameter.
- Pattern CHOP - Added 'Random Non-Repeating Integers' to the 'Type' menu which will randomly change values whenever the 'Randomize' pulse parameter is pressed.
- Web Server DAT - New DAT which runs a web server in TouchDesigner, currently supports handling of HTTP requests and webSocket connections. How client requests are handled is left up to the user via a 'Callbacks DAT'.
- Web Client DAT - New DAT that acts as a web client. This replaces the deprecated Web DAT. Includes
- SocketIO DAT - New DAT for extended socket.io functionality, separate from the older functionality of the WebSocket DAT.
- Raster SOP - New SOP that takes a TOP and converts it into a single-line SOP that can be used with the Laser CHOP.
- Aligning SOPs to their X, Y, and Z axes: Rectangle SOP / Box SOP / Circle SOP / Grid SOP / Sphere SOP / Superquad SOP / Torus SOP / Tube SOP - Added 'Anchor' parameters to main SOP generators. The position stays stationary regardless of rotate and scale settings.
- Text SOP - Added 'Vertical Align' parameter with options: First Line, Top, Center, Bottom. The chosen field will be aligned to the x-axis.
- Text SOP - Added 'Scale Font to BBox Height' parameter to scale the font's vertical size so it's based on the vertical bounding box of the font, rather than the typical way a font is sized.
- Select SOP - Now allows multiple input ops to be specified in the 'SOP' parameter, acting like a Merge SOP.
- Merge SOP - Added 'SOPs' parameter to accept multiple SOPs by reference.

BACKWARD COMPATIBILITY - Transform CHOP was previously using rotate order as the output order even if the 'Custom Output Orders' was On.
BACKWARD COMPATIBILITY - Transform CHOP had Output Channels parameter removed, replaced by output toggles to customize the output channels.
BACKWARD COMPATIBILITY - Function CHOP fixed an issue where tanh(x) was being calculated as tan(x).
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 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.
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.
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.
An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.
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".
A Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that only contain the CHOP channels' samples between the last and the current cook frame.
