====== The Growth Gallery of Human Embryo Digestive System  ======
Modeling the human embryo digestive system with HyperFun modeling language. Models are generated from a 2D line segments skeletons. The HyperFun file format and the final images are generated with POVray raytracing program.

| Artistic drawing of 3 months old human embryo. | | 2D skeleton contains 6 parts and 177 line segments. ||

Skeleton is a set of 3D points connected by lines. To better model the features of organ growth and different thickness of whole digestive system, skeleton is divided to 6 parts. It is modeled in 3D Studio Max v.4 and converted to HF format. In HF format skeleton is recognized as a set of line segments (skeleton primitives), where each of the line segments has his own HF parameter S and T. S and T parameters define the Line segments are connected by operations union or blending union. There are 177 line segments in our model. The parameters for the each parts of the model are as follow:
