9.1.7.2 SMC_TeachCoordinateSystem
This POU of SM_Trafo.lib helps the user to calculate the vectors of a new coordinate system
which he wants to "teach". As inputs the source of the new coordinate system and a
random point are transferred to the x and y xis, respectively. As outputs the POU provides
the translation vector and the unit vectors of the new coordinate system. Furthermore it
calculates the quality of the input parameters (angle between x and y axis should be 90°).
Inputs (VAR_IN)
vOrigin: SMC_Vector3D
Source position of the new coordinate system.
vPointOnX, vPointOnY: SMC_Vector3D
Position of a point on the x or y axis.
Outputs (VAR_OUT)
vX, vY, vZ: SMC_Vector3D
Unit vectors of the new coordinate system.
vTranslation: SMC_Vector3D
Translation vector. Vector from the old coordinate origin to the new one with reference to
the old coordinate system
fQuality: LREAL
Quality of the input parameters; value from 0 to 1, where 1 = optimum (vX, vY are
orthogonal), and 0 = vX and vY are invalid.
