The modelling in OpenInventor, 3DS, etc. can not do.
Fractals are limited.
Parametric objects with tons of parameters are complex to implement. The result would be a modeller in which user specifies the DNA, then watches the real-time growth and can export the end result. For the final demonstration we plan grass, flowers, trees and a face. I believe the project is fairly simple and fairly revolutionary. I also argue that any 3D object can be modelled this way.
