SignalArrow
Visualizing an arrow with dynamically varying size in frame_a based on input signal
Library
Modelica/Mechanics/MultiBody/Visualizers
Description
Model SignalArrow defines an arrow that is dynamically visualizedat the location where its frame_a is attached. Thevector from the tail to the head of the arrow,resolved in frame_a, is defined via the signal vector ofthe connector r_head (Real r_head[3]):
The quantity parameter defines what the vector represents, allowingtools to scale e.g. forces and torques differently in a consistent way.For the default value RelativePosition the obvious scaling is1 and the relative position is shown as is.
The tail of the arrow is defined with input r_tailwith respect to frame_a (vector from the origin of frame_a to the arrow tail).
