Summary
[edit]

The Angle CHOP is a general purpose converter between degrees, radians, quaternions and vectors. Different formats assume a specific ordering of input channels.

Parameters - Angle Page

Input Units inunit - - Units of incoming channels:

  • Degrees degrees -
  • Radians radians - (a radian is 57.29 degrees, with 3.14 (Pi) radians in a half-circle).
  • Quaternions quaternions - Input is 4 channels consisting of x, y, z, and w values.
  • Two Vectors twovectors - Input is 6 channels comprising of x, y, z of one vector, followed by x, y, z of 2nd orthogonal vector.

Input Order inorder - - The order that rotation angles are assumed to be applied in (Euler angles as they are called). Applicable when converting to and from Quaternions or Vectors.

  • Rx Ry Rz xyz -
  • Rx Rz Ry xzy -
  • Ry Rx Rz yxz -
  • Ry Rz Rx yzx -
  • Rz Rx Ry zxy -
  • Rz Ry Rx zyx -

Output Units outunit - - Units of outgoing channels:

  • Degrees degrees -
  • Radians radians -
  • Quaternions quaternions -
  • Two Vectors twovectors -

Output Order outorder - - The order that rotation angles are assumed to be applied in (Euler angles as they are called). Applicable when converting to and from Quaternions or Vectors.

  • Rx Ry Rz xyz -
  • Rx Rz Ry xzy -
  • Ry Rx Rz yxz -
  • Ry Rz Rx yzx -
  • Rz Rx Ry zxy -
  • Rz Ry Rx zyx -


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).
