Non-Photorealistic Rendering of Plants and Trees

The rendering technique described in this work allows non-photorealistic rendering of plants and trees. Our method is based on the general method proposed by Barbara Meier in 1996. RL-Systems are used to model a tree, allowing the generation in a single step of both the tree geometry and the set of brush strokes needed for later rendering. It can be applied to traditional animation, and to project presentation in architecture and interior design. The main advantage of our method is the integration of the processes of particle generation and geometry generation, facilitating the random perturbation of the model parameters, and the combination of elements to produce several levels of detail.
