Major New Additions
Point Cloud Support Point Clouds and general data with TOPs - Doing more work with the GPU.
- Point File In TOP - .
plyfiles supported. 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).
- Supports converting shapes into point clouds when loading .obj files.
- The operator's viewer defaults to opening in 'normalized split' mode.
- 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
- The number of points in the original source file is now displayed in the Info CHOP.
- Can store and display header data in an attached Info DAT (currently supported in .FITS and .PLY files).
- Point clouds that exceed the maximum size supported by the graphics card are now clamped with the output points sampled evenly from the total available points.
- If the output resolution is smaller than the source texture, points are now evenly sampled from the source rather than cropping.
- Point File Select TOP - This new TOP can select channels from a Point File In TOP, useful when multiple buffers exist.
- TOP Viewer modes have been extended.
- Added total number of pixels to TOP popup info dialog.
- '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 Cloud Workflow
Better Support for .exr Files - See also OpenEXR.
- Point File In TOP - .exr files are now loaded in RGBA order so that they match files loaded with the Movie File In TOP.
- Movie File In TOP

- Added parameters to give custom names to the RGBA channels in an .exr files.
- Custom header data can now be written to files by attaching a Table DAT (currently only supports EXR sequences).
- Added toggle to flag .exr files as containing point cloud data when saved so that they can be loaded directly into the Point File In TOP.

Geometry Instancing with TOPs
- Keep data on the GPU by going directly from TOPs to GPU instancing.
- 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.
- New 'Active' parameter available for instancing to control on a per instance basis if each instance should be shown in the render.

- Geometry viewer now saves the last home bounds to preserve the view when saving.
- Parameter UI Improvements - Previously some parameters were a list of duplicates when multiple copies of that parameter might be used. Examples of this are the GLSL MAT's 'Uniform' parameters (8 copies), a Component's 'Extension' parameters (4 copies), a Constant CHOP's channel creation parameters (40 copies), etc. Now these parameters start out with just 1 copy of the parameter and you can Add or Remove parameters when needed. This has the following advantages:
- Cleans up long lists of the same parameter that might not be used. For example, the GLSL MAT's Sampler pages would always have 8 Uniform parameters, even when not used. Now it starts with 1 and you can add the number you need.
- Cleans up duplicate parameter pages on some OPs. For example, the GLSL MAT previous had 'Samplers 1' and 'Samplers 2' pages just to get 16 Uniform parameters. Duplicate pages are no longer needed so now there is only one 'Samplers' page where you can add the exact number of Uniform parameters required.
- Removes the limit on the number of parameters available. For example, the Constant CHOP used to be limited to 40 channel parameters, the Point SOP used to be limited to 4 'Custom Attrib' parameters, these are no longer limited as you can create any number of parameters required (NOTE: some are limited by other factors such as limited GPU resources).

- MoviefileinTOP Class.sourceChannels - lists the available channels in the file e.g. R, G, B, A for typical color images, but could be more for some formats like .exr files. Extra available channels can be accessed using the Point File In TOP and Point File Select TOP.
- MoviefileinTOP Class - Added python function that returns a tuple with the available channel names in the file.
- textTOP_Class / textSOP_Class - Improvements
lines()method to inspect the text after it has been formatted by things such as word wrap.
- Python objects returned from
lines()method now have
- Added members to access more font metrics such as ascender, descender, capHeight, lineGap and xHeight.
- SOP Class maximized
.min .max .sizemembers
- Point Class.normP returns the normalized point within SOP bounding box. (This is equivalent to $BBX $BBY $BBZ in Tscript). Previously this was limited to a few specific SOP parameters.

Major Feature Addition
- Nvidia Flex - Added support for Nvidia Flex which is a particle-based physics simulator that uses a unified particle representation for all object types. All bodies in a simulation (with the exception of static shapes/surfaces) are composed of particles. Their behavior in the simulation will be defined by the type of substance: rigid, soft, fluid, rope, cloth. Because all bodies in a Flex simulation are represented by particles, all substances can be simulated together seamlessly without the need for multiple solvers. Requires Nvidia GPU on Windows.
- TouchDesigner's support for Nvidia Flex includes:
- Nvidia Flex Solver COMP - A new solver component that runs the Nvidia Flex simluation.
- Nvidia Flex TOP - A new TOP that can grab the simulation data from an Actor COMP and make it available in TOPs.

- TDAbleton - Major update to version 1.23
- Auto-Installer - On the Utilities page, you will find settings for automatically installing TDAbleton. This copies all files and sets up the user folder in Ableton. Notes: You must run this install with Ableton Live closed. You still have to select the TouchDesigner Remote Script in Ableton Preferences the first time you run TDAbleton. If you just installed Live, you must run it once and close it before installing TDAbleton so that default preferences are set up.
- Bindable Ableton Parameters - All the parameters for navigating the Live Object Model are now bindable. Bind them to or from any menu parameter and the proper navigation parameters will be set up in the bound menus. Example: /project1/Demo/parameterBinding in demo
- Level Devices in Master and Send Tracks - Fixed bug where abletonLevel devices didn’t send properly from Master and Send tracks.
- TDAbleton Master Max Device - Ableton now displays its IP address here for easier setup. There is now an on/off switch on the device to control master time transmission.

- Bindable Ableton Macros - Similar to Bindable Ableton Parameters above, binding to Rack and Level macros will keep the parameter labels in sync. If you change a label of a par bound to a Rack or Level macro manually, your label will not be kept in sync.
- Master Parameters Bound to Package - All TDAbleton master parameters are now available at the top level of the package via binding.
- Connection Notification - Added popup to indicate when not connected. No longer starts with error marker if no Ableton Live is found.
- Cook optimizations - Reduced number of nodes that are constantly cooking.
- Bug Fixes - The autofix code for fixing duplicate names in Live are working in many cases where they preciously did not. Eliminated textport spam when TDAbleton is deleted and when Jump to Cue is invoked. abletonMIDI now shows device on/off state correctly.
- Palette:firmata - Overhauled
- Bottom-up rebuild of firmata component.
- Saves configuration and uploads it to firmata.
- Proper servo configuration.
- Added sampling interval setting.
- Palette:pointMerge - New component added to the PointClouds folder which packs the pixels of two input images into a single output image.
- Palette:pointRepack - New component added to the PointClouds folder which can be used rearranges the pixels of the input image to fit into an output image of a given size.
- Palette:pointTransform - Now has 'Post' page mimicking the Transform SOP's Post page.
- Widgets - This version fixes some issues with widget caching for knobs and sliders, and fixes the parameter order for String Field sub-widget which was reversed.
- COMP.save(password=None) / COMP.loadTox(password=None) methods now have optional password to encrypt/decrypt tox files to disk. Unlike Component privacy, this only applies to the disk file itself, not its operation once inside the network.
- COMP Class.saveExternalTox(recurse=False, pasword=None) -> count - Saves out the contents of any COMP referencing an external .tox and returns the number of components saved. If password is supplied it is used to encrypt the resulting disk files.

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 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.
(1) A Geometry Component can render its SOP geometry many times using CHOP samples, DAT rows, TOP pixels or SOP points, (2) An instance is an OP that doesn't actually have its own data, but rather just refers to an OP (or has an input) whose data it uses. This includes Null OPs, Select OPs and Switch OPs.
(1) The TouchDesigner window is made of a menu bar at the top, a Timeline at the bottom, plus one of a choice of Layouts in the middle. A Layout is made on one or more Panes, each Pane can contain a Network Editor, Viewer, Panel, etc. See Pane and Bookmark. (2) Nodes in a network are arranged using Layout commands in the RMB menu.
To pulse a parameter is to send it a signal from a CHOP or python or a mouse click that causes a new action to occur immediately. A pulse via python is via the
.pulse() function on a pulse-type parameter, such as Reset in a Speed CHOP. A pulse from a CHOP is typically a 0 to 1 to 0 signal in a channel.
An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.
Binding is a Parameter Mode that ties two or more values together, where changing the value of any one of the bound values changes all of them. The actual value is stored in one place, whichever value is at the top of the bind chain, called the bind master. Parameters can be bind references, bind masters, or both. Table cells and bindCHOP channels can be bind masters only.
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.
The frame rate that TouchDesigner's Timeline uses. Equal to the Frames per Second value
A built-in panel in TouchDesigner that contains a library of components and media that can be dragged-dropped into a TouchDesigner network.
Unicode is fully supported in TouchDesigner. Unicode can be typed into parameters, DATs, Python scripts etc. Unicode encoded text files can be loaded into DATs. File paths can include any unicode character that is legal for a file path.
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.
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.
TouchDesigner is a hierarchy of components. "root" is the top-most network in the hierarchy. The Path is simply
/. A typical path is
The operating system's holder of files and other folders (directories). It does not refer to operators within TouchDesigner. See Network Path.
Parameters in TouchDesigner are an operator's settings (numbers, menus, flags, strings, paths) which the user can alter. Parameters for any operator can be opened by right-clicking on the operator and selecting "Parameters..." A currently selected operator's parameters can be viewed in a Network Editor by pressing the keyboard shortcut 'p'.
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.
Each operator can have a set of text strings that are its "tags". You can set them and search for them within TouchDesigner.
A frame within the Animation component which holds a channel value, slope, acceleration and interpolation type, used to determine the values of the channel which are not keyframes.
Creates a new component for every line in a table. Unlike Clone, it automatically creates copies of a master component.
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.
