This thesis consists of two parts. The first part is an art project in which we collaborated with a student from the Academy of Fine Arts and Design. In the project we simulate the life cycle of abstract plants using L-Systems. L-Systems is a formal grammar structure which employs parallel transcription of grammar rules to transcribe one text string into another. The geometric interpretation of text strings is the drawing of straight lines. With the appropriate sequence of implemented grammar rules, we obtain a result that draws plant-like forms.
In the second part of the thesis we simulate growth of the actual tree species. The simulation is drawn using an algorithm that we obtain through analysis of the architecture and growth of tree species. Our goal is that an expert would be able to recognize the tree species whose growth we are simulating. In the thesis we define the rules for the simulation of fir tree growth. Such a simulation shows a more realistic development of the tree species over a long period of time, and is therefore useful for landscape architecture design and planning, and similar applications in which the accurate projected growth of trees is relevant.
