SMC_CoordinateTransformation3D (FB)

FUNCTION_BLOCK SMC_CoordinateTransformation3D

This function block will calculate the coordinates of a point given in respect of the new coordinate system and transformed to the old coordinate system. For this purpose, the coordinate transformation is defined by the translation of the origin and the new unit vectors (given in respect of the old coordinate system).

For detailed information of transformation modules see the survey on Coordinate Transformations.
