Résumé
During growth, a plant makes use of an architecture whose characteristics are continually modified with time. The orientation of the axes, the leaves, and the flowers must be dynamically controlled in the creation of realistic 3-D computer graphic animations of the plant development. Practical solutions adapted to botanical principles are proposed in this document. The solutions allow for modification in relation to time, scale, position and orientation of the organs, all of which are calculated from the plant’s architectural fundamentals (the branching, the phyllotaxy, the length of the internodes, etc.)
