T
Builds the motor translating by (dx, dy).
The translator 𝟙 + (dx/2)·e42 − (dy/2)·e41 — R's at-infinity limit (see Motor). The versor representation's half coefficients stay inside the factory: p * T(dx, dy) moves p by exactly (dx, dy).
Return
The translator Motor.
Parameters
dx
The Euclidean x-displacement.
dy
The Euclidean y-displacement.
Builds the motor translating by direction — a free vector's magnitude and orientation taken as a displacement.
The translator whose generator is the Direction itself: its px/py blades are exactly the translator's, so the direction's length is the displacement length.
Return
The translator Motor.
Parameters
direction
The displacement.
