Interactive flower modeling with 3Gmap L-systems
Résumé
Flowers have quite an intricate structure consisting of numerous components which, in turn, have an enormous variety of shapes.Therefore, it is not an easy task for computer graphics to simulate such kind of natural phenomena. We propose in this paper an appli- cation of the 3Gmap L-systems to flower modeling by growth simulation. Our approach combines L-systems grammar writing with interactive control of parameter settings. The L-systems are used for creating the entire model, with stems,stamens, petals, leaves,etc., by simply operating with 3Gmap volumes. The presented contributions will make the task of a user more obvious and intuitive enabling her/him to create more accurate models. Moreover the way the model is built allows us to take into account its internalstructure. As the flower tissue is non-homogeneous, the possibility of obtaining its internal composition could be quite useful for rendering, allowing for instance to render more accurate subsurface scattering.
