Summary
[edit]

The Logic CHOP first converts channels of all its input CHOPs into binary (0 = off, 1 = on) channels and then combines the channels using a variety of logic operations.

NOTE: The Logic CHOP is superceded by more convenient operators like the CHOP Execute DAT or the Text DAT which will run their scripts when CHOP channels change.

The Logic CHOP performs logic operations on the samples in CHOP channels. The channels of a CHOP can be combined into one channel, and several CHOPs can be combined into one CHOP.

With one input CHOP, you can invert the values of each sample. You can also do logic operations on the samples of one channel by the samples in the other channels, reducing N channels down to one. You can combine by applying an "or", "and", etc..

With two or more CHOP inputs, you can combine the channels in one CHOP with the channels in all the other CHOPs, reducing N CHOPs to 1.

To do math operations (add, multiply, ...) between channels or CHOPs, use the Math CHOP.

Parameters - Page

Template:ParMenu Template:ParMenu Template:ParMenu Template:ParMenu Template:ParMenu Template:ParMenu Template:ParFloat


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).
