Information

A function to calculate the initial position and orientation angle of a free-floating beam. The beam is assumed to hang at the bottom intersection between two cloths. The function takes in the four points that would be used to define a "bent cloth" of the same configuration and uses the algorithm developed to calculate the positions of the outside bottom points of a hanging cloth (see cloth_bend documentation). These points are taken to be the end points of the beam. The orientation angles are calculated from these end points.
