Extend CHOP
Summary[edit]
The Extend CHOP only sets the "extend conditions" of a CHOP, which determines what values you get when sampling the CHOP before or after its interval.
The Extend CHOP has separate menus to control both the pre-interval and the post-interval. For example, before the interval, you may want to hold a constant value, and after the interval you may want to cycle or repeat the curves in the interval.
To shorten or lengthen the interval (the start or end of the CHOP), use the Trim CHOP.
You can see the state of Extend Conditions in the pop-up info of any CHOP (use middle-mouse click on the CHOP).
Parameters - Extend Page
Left Behavior left
- ⊞ - The extend condition before the CHOP interval. They are:
Template:Menuitem Template:Menuitem Template:Menuitem Template:Menuitem Template:Menuitem Template:Menuitem
Right Behavior right
- ⊞ - Extend condition after the interval. Same options as Extend Left.
Template:Menuitem Template:Menuitem Template:Menuitem Template:Menuitem Template:Menuitem Template:Menuitem
Default Value defval
- The value used for the Default Value extend condition.
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. See Pattern Matching.
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 hasgeo1/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).
Operator Inputs
- Input 0: -
