Visual modeling of stomach growth on the basis of L-systems

A parametric L-system (Lindenmayer system) is developed to model the growth and structure changes of human stomach over the time starting in the third week and going on into week four of human embryo development. The model takes into account what is known about embryo movement during growth. The framework uses the formalism of L-systems with constructs that are dependent on time and smooth growth functions. The method captures the development of human embryo stomach consistently with static observations of the real embryo. Computer animation and visual interpretation make it possible to understand the modeled processes accurately and lead to realistic exploration of the human stomach at various stages of development.
