Time Slice - 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 - To determine which channels get affected, some CHOPs use a Scope string on the Common page.
Patterns can be used in the Scope:
* (match all channels and therefore affect all channels),
? (match single character. See Pattern Matching.
Sample Rate Match - Handle cases where multiple input CHOPs' sample rates are different. When the CHOP needs to combine inputs with different sample rates, the Sample Rate Match Options offers these choices:
- Resample At First Input's Rate - Use rate of first input to resample others.
- Resample At Maximum Rate - Resample to the highest sample rate.
- Resample At Minimum Rate - Resample to the lowest sample rate.
- Error if Rates Differ - Doesn't accept conflicting sample rates.
When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.
Export Method - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.
- DAT Table by Index - Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
- DAT Table by Name - Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
- Channel Name is Path:Parameter - The channel is the full destination of where to export to, such has
Export Root - 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 - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
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.
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.
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.
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'.
