Optimized stereographic projection at the example of a sphere

New protosoma Q0, minimizing the helical parameter φi
Grahic Jump Location
Definition of the metric with a stereographic projection, and the Euclidean norm, at the example of a sphere
Grahic Jump Location
The metric is not right-invariant
Grahic Jump Location
Without optimization (Qi,i=1,[[ellipsis]]4 are given somen, Q̄0 is the protosoma)
Grahic Jump Location
With optimization (Q0 is the new protosoma after optimization)
Grahic Jump Location
Not optimized and optimized somen motion using the Chaikin algorithm (The darkblue lines represent the motion with optimized projection)
