The Interpolate CHOP treats its multiple-inputs as keyframes and interpolates between them. The inputs are usually single-frame CHOP channels like those produced by a Constant CHOP. The Interpolate CHOP first sorts the input CHOPs in time (without shifting them) and interpolates between them to fill the gaps.
The number of channels in the output is the same as the number of channels in the first input.
If a channel is missing in an input, and Match By is set to Channel Name, it is treated as if there is no keyframe at that frame for that channel, and the interpolation occurs between CHOPs before and after that frame.
Parameters - Interpolate Page
blendfunc - ⊞ - The shape of the interpolation curve:
lin- A straight line.
- Ease in
ei- Exponential rise.
- Ease out
eo- Exponential fall.
- Ease in Ease out
cos- Half cosine blend.
cub- A cubic spline.
add- Overlapping parts, if any, are added.
- Hold Previous
overlap - ⊞ - If an input is not a single frame, and if there are overlaps in the input CHOPs, an option is used to resolve the conflict.
- Average Overlaps
avg- Combine the conflicting channels by averaging them.
- First Segment has Priority
first- Use the segment with the earliest start time.
- Last Segment has Priority
last- Use the segment with the latest start time.
match - ⊞ -
- Channel Number
- Channel Name
Parameters - Common Page
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 - 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.
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
autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
- Input 0 -
