Tree modelling in virtual reality environment

Abstract

In this chapter, various approaches for individual tree modelling are considered, among which the L-systems are prevailed. The fundamentals of the L-systems are situated in one of sub-sections. Usually a modelling, using the L-systems, means a viewpoint of a scene from the Earth’s surface. The modelling results based only on the L-systems cannot provide good realistic virtual interpretation. However, a compact storage of individual tree in mathematical form has also a great meaning, especially during a modelling of the forest virtual scene. Some methods of realistic modelling are discussed in this chapter. Two principally different types of trees, the broad-leaved and the coniferous, have the own specialties of modelling. Notice that a conifer branching with leaves has more complex structure in comparison to a broad-leaved branching. At the ending of this chapter, some results received by use of the designed experimental software tool TreesEditor, v. 1.04 are presented.
