Morphogenetic Surface Structures is a research program to generatively model surfaces that actualize Lindenmeyer systems in an interactive environment. This environment adds controlled flexibility to the system which can emulate real world constraints. MoSS allows the designer to set a base grammar and guide growth through the application of boundary and field conditions. The modeling of multiple surfaces with variable grammars is implemented. MoSS outputs files to CAD/CAM applications allowing for three-dimensional testing in physical models. The investigative software is integrated with Alias|Wavefront Studio via the Applications Programming Interface of Studio which supports development in C++.
