We study an ordered pair of functions which determines a regular space curve up to a direct similarity. The first function is called a shape curvature and the second one a shape torsion. We prove an extension of the fundamental theorem of space curves relating to the group of direct similarities. We also propose a direct way for recovering a space curve from its shape curvature and shape torsion.
