This technique is inspired from genetic coding. The idea is quite simple, from a unique low poly base mesh and some vector maps, we store a genotype-like description to create a new model.The global topology has to be the same in order to match targets such as ears for example. But as we depend on the vector map, the different goal models can contain any amount of polygon.
This picture illustrates this technique with two goal meshes. It looks like a common morphing but, with masks and multiple targets, the intermediate models would be very different from each sources.
