Summary

This CHOP generates S curves.

PythonIcon.pngscurveCHOP_Class



Parameters - S Curve Page

Curve Type type - -

  • Half Cosine halfcosine -
  • Logistic log -
  • Arctangent atan -

Length length - Set the number of samples for this CHOP.

Prepend prepend - Add this number of samples to the beginning of the curve.

Append append - Add this number of samples to the end of the curve.

Steepness steepness - Controls the steepness of the S Curve.  

Linearize linearize - Control the amount of cruvature in the curve.  

Bias bias - Move the curve's bias backward or forward.  

From Range fromrange- - Specify the low and high range of the input index.

"" fromrange1 -


"" fromrange2 -

To Range torange- - Specify the low and high range of the curve.

"" torange1 -


"" torange2 -



Parameters - Channel Page

Channel Names channelname - You can creates many channels with simple patterns like chan[1-20], which generates 20 channels from chan1 to chan20, or t[xyz] which generates tx, ty and tz. See the section, Common CHOP Parameters for a description of this and all Options. See Scope and Channel Name Matching Options.

Sample Rate rate - The sample rate of the channels, in samples per second.  

Extend Left left - - The left extend condition (before range).

  • Hold hold -
  • Slope slope -
  • Cycle cycle -
  • Mirror mirror -
  • Default Value default -

Extend Right right - - The right extend conditions (after range).

  • Hold hold -
  • Slope slope -
  • Cycle cycle -
  • Mirror mirror -
  • Default Value default -

Default Value defval - The default value for extend conditions.  



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.

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.

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.

A Time Slice is the time between the last cook frame and the current cook frame. In CHOPs it is a set of short channels that only contain the CHOP channels' samples between the last and the current cook frame.

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.
