miofPLA0B0

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Kinematics and Frames

returns the index of the minimal relative angle to the axis between A0 and B0

Description

This function is used to find the circshift index for the point list of a fourbar-linkage. The original PL describes a circle around P0 starting at 0 degrees to 360 degrees. However, it makes more sense to rotate the PL relative to the axis A0B0. Therefore all results of invkinplan2 have to be circshifted.
This auxiliary function is used in fourBarLinkageplotanim.

Syntax

mi=miofPLA0B0(PL,A0,B0)

Input Parameter

PL: Point List (A1) of a fourbar linkage
A0: Base Point A0
B0: Base Point B0

Output Parameter

mi: shift index for PL=circshift(PL,-mi)

Examples


miofPLA0B0(PLcircle(10),[0 0],[10 10])
miofPLA0B0(PLcircle(10)+[5 4],[5 4],[10 10])
% mi=miofPLA0B0(PL,A0,B0); PL=circshift(PL,-mi); B1=circshift(B1,-mi);
