Summary
[edit]

The Import Select CHOP is used to specify CHOP channels from an importing file such as FBX COMP or USD COMP. One of the main purpose of these channels is to represent the changes of transformation of different primitives or the state of some dynamic features of importing file. The Import Select CHOP can have its own animation controls within the Play page or use the settings from its parent COMP.

Parameters - Playback Page

Use Parent Animation useparentanim - A toggle to specify whether to use the parent COMP animation controls or have a custom setting for this SOP.   Animation animation - Specifices the animation name (if any is specified) from the importing file that this CHOP represents.   Shift Animation Start shiftanimationstart - A toggle to specify whether to shift the animation to the start of animation indicated in the importing file.   Sample Rate Mode sampleratemode - - A menu to choose between the FPS or use a custom sample rate.

  • File FPS filefps - uses the FPS from what is defined in the importing file.
  • Custom custom - a desired value specified by Sample Rate parameter.

Sample Rate samplerate - It is used to specify the sample rate (FPS) for the animation. This parameter is disabled by default and can be enabled once the Custom option is selected from the Sample Rate Menu.   Play Mode playmode - - A menu to specify the method used to play the animation.

  • Locked to Timeline lockedtotimeline - This mode locks the animation position to the timeline. The parameters Play, Speed, Index, Cue and Cue Point, are disabled in this mode since the timeline is directly tied to animation position.
  • Specify Index specifyindex - This mode allows the user to specify a particular index (position) in the animation using the Index parameter below. Use this mode for random access to any location in the animation.
  • Sequential sequential - This mode continually plays regardless of the timeline position (the Index parameter is disabled). Play, Speed, Cue, and Cue Point parameters below are enabled to allow some control. The default is set to this value.
  • Output Full Range outputfullrange -

Index index - This parameter explicitly sets the animation position when Play Mode is set to Specify Index. The units’ menu on the right lets you specify the index in the following units: Index, Frames, Seconds, and Fraction (percentage).   Index Unit indexunit - - Specifies a unit type for Index. Changing this will convert the previous unit to the selected unit.

  • Frames frames -
  • Seconds seconds -
  • Fraction fraction -
  • Index indices -

Play play - A toggle that makes the animation to play when it sets to ON. This Parameter is only available/enabled if the Sequential mode is selected from the Play Mode.   Speed speed - This is a speed multiplier which only works when Play Mode is Sequential. A value of 1 is the default playback speed. A value of 2 is double speed, 0.5 is half speed and so on.   Trim trim - A toggle to enable the Trim Start and Trim End parameters.   Trim Start tstart - Sets an in point from the beginning of the animation, allowing you to trim the starting index of the animation. The units’ menu on the right let you specify this position by index, frames, seconds, or fraction (percentage).   Trim Start Unit tstartunit - - Specifies a unit type for Trim Start. Changing this will convert the previous unit to the selected unit.

  • Frames frames -
  • Seconds seconds -
  • Fraction fraction -
  • Index indices -

Trim End tend - Sets an end point from the end of the movie, allowing you to trim the ending index of the animation. The units’ menu on the right let you specify this position by index, frames, seconds, or fraction (percentage).   Trim End Unit tendunit - - Specifies a unit type for Trim End. Changing this will convert the previous unit to the selected unit.

  • Frames frames -
  • Seconds seconds -
  • Fraction fraction -
  • Index indices -

Cue cue - A toggle to jump to Cue Point when it is set to ON and it stays at that position. Only available when Play Mode is Sequential.   Cue Pulse cuepulse - When pressed the animation jumps to the Cue Point and continues from that point.   Cue Point cuepoint - Set any index in the animation as a point to jump to.   Cue Point Unit cuepointunit - - Specifies a unit type for Cue Point. Changing this will convert the previous unit to the selected unit.

  • Frames frames -
  • Seconds seconds -
  • Fraction fraction -
  • Index indices -

Extend Left textendleft - - Determines how the parent COMP handles animation positions that lie before the Trim Start position. For example, if Trim Start is set to 1, and the animation current index is -10, the Extend Left menu determines how the animation position is calculated.

  • Hold hold -
  • Cycle cycle -
  • Mirror mirror -

Extend Right textendright - - Determines how the parent COMP handles animation positions that lie after the Trim End position. For example, if Trim End is set to 20, and the animation current index is 25, the Extend Right menu determines how the animation position is calculated.

  • Hold hold -
  • Cycle cycle -
  • Mirror mirror -

Parameters - Common Page

Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.  

Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.  

Sample Rate Match srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.

  • Resample At First Input's Rate first - Use rate of first input to resample others.
  • Resample At Maximum Rate max - Resample to the highest sample rate.
  • Resample At Minimum Rate min - Resample to the lowest sample rate.
  • Error If Rates Differ err - Doesn't accept conflicting sample rates.

Export Method exportmethod - - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.

  • DAT Table by Index datindex - Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
  • DAT Table by Name datname - Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
  • Channel Name is Path:Parameter autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.

Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.  

Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).

An Operator Family which operate on Channels (a series of numbers) which are used for animation, audio, mathematics, simulation, logic, UI construction, and many other applications.

An Operator Family that contains its own Network inside. There are twelve 3D Object Component and eight 2D Panel Component types. See also Network Path.

An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.

samples-per-second of a CHOP. Each CHOP in your network has a sample rate, whether it is used or not. The overall timeline has a "frame rate", which is the number of animation frames per second, generally your monitor display frequency.

The panel at the bottom of TouchDesigner, it controls the current Time of the full system or just one component.

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.

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 from a CHOP is typically a 0 to 1 to 0 signal in a channel, and a pulse via python is via a .pulse() call on a pulse-type parameter, such as Reset in a Speed CHOP.

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.

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.

Exporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.

An Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a command Script, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.

The location of an operator within the TouchDesigner environment, for example, /geo1/torus1, a node called torus1 in a component called geo1. The path / is called Root. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.

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'.

TouchDesigner is a hierarchy of components. "root" is the top-most network in the hierarchy. The Path is simply /. A typical path is /project1/moviein1.
