| Abstract: | In this paper, we introduce an extended L system (ELSYS) and its 3D graphics system. Moreover, the design and display of 3D natural plant landscape based on this system has been presented. Firstly, the definition of L system, the relation of L system and generation of plant and fractal graphics, and the structure of the L system compiler have been given. Then, ELSYS language and programming have been introduced. Lastly, the procedure of designing 3D landscape, such as wheat and tree, with the ELSYS has been presented. |
