rotationInterpolation is undoable, queryable, and NOT editable.

The rotationInterpolation command converts the rotation curves to the desired rotation interpolation representation. For example, an Euler-angled representation can be converted to Quaternion.

Return value


In query mode, return type is based on queried flag.


curve, rotation, interpolation, quaternion, euler


Long name (short name) Argument types Properties
convert(c) string createquery
Specifies the rotation interpolation mode for the curves after converting. Possible choices are "none" (unsynchronized Euler-angled curves which are compatible with pre-4.0 Maya curves), "euler" (Euler-angled curves with keyframes kept synchronized), "quaternion" (quaternion curves with keyframes kept synchronized, but the exact interpolation depends on individual tangents), "quaternionSlerp" (applies quaternion slerp interpolation to the curve, ignoring tangent settings), "quaternionSquad" (applied cubic interpolation to the curve in quaternion space, ignoring tangent settings)

Flag can appear in Query mode of command Flag can have multiple arguments, passed either as a tuple or a list.

Python examples

import maya.cmds as cmds

# Converts "nurbsCone1_rotateX" and its sibling curves to quaternion tangent dependent format.
cmds.rotationInterpolation( 'nurbsCone1_rotateX', convert='quaternion' )
