Return a temporal value translated by given offsets

translate({tpose,tposechain},deltax float,deltay float,deltaz float=0)
  → {tpose,tposechain}

A vertical offset takes a two-dimensional value out of its plane, so the result is three-dimensional.

The chain of every instant moves its first link, which is expressed in the outer frame of the chain, and keeps the others.

The motion is a planar map, so a geodetic value raises an error.

rotate({tpose,tposechain},angle float) → {tpose,tposechain}

Return a temporal value rotated counter-clockwise about the x axis

rotateX({tpose,tposechain},angle float) → {tpose,tposechain}

The rotation takes a two-dimensional value out of its plane, so the result is three-dimensional: each position gains the height the rotation gives it, and each orientation is the rotation composed with the angle about the vertical that the value states.

The chain of every instant moves its first link, which is expressed in the outer frame of the chain, and keeps the others.
