The Environmentally sensitive L-system expresses the shapes of topiary by "Query module". This L-system is hard to model the tree that have multilevel growth domain, because this system confine limited the growth using a unit volume. We extended environmentally sensitive L-system for multilevel and multimodal topiary and added the rule of main-branch and growth-area-variable in this paper. If the main-branch moves into another domain in the growing process, it is branched with the new domain as its growth-limitation area. Growth-area variable is used for checking area. We also designed new L-system for leaves. This designed L-system generated various shaped leaves from same rule by changing parameter value. The proposed tree modelling technique is possible to model various sort of garden tree. The proposed tree modelling technique is possible to model multilevel and multimodal tree.
