Left: the self-intersection free linear interpolation between the smooth backbones of the un- and phosphorylated forms of Odhl (NMR structures 2KB3 and 2KB4). Center: the interpolation between two configurations of the SH3 domain given by the A chains of 1AOJ and 1I0\(\hbox {C}^*\) has a self-intersection between line segments approximately 10 and 25 residues from the C-terminal. Right: the interpolation between the 52 residue long helix 1IK7 A \(\hbox {chain}^*\) and its aligned part of the 102 residue folded 1D2Z C chain is self-intersection free
