Shape variation exploration by libcmaes?

I have seen the libcmaes, which is a good contribution. I am wondering if this library can be applied for real application.
For example the task of modeling a 3D model, based on genetic algorithm to find the best "fit" one with repect to a certain requirement.

I am not I am in the right direction, because I am lack of knowledge of GA and cma-es. So could you kindly give me some advise on this topic.
