Modelling tree structures using a single polygonal mesh

This paper presents a method to obtain a polygonal mesh representing the ramified structure of a tree. We use a method based on L-systems to model the tree. A refining process is applied once the model of the tree is obtained. Soft transitions are achieved in the areas of the tree where there are divisions. In this way, we avoid the possible superimposition and discontinuity problems in geometry. As a result of this process, a continuous polygonal mesh is obtained. This mesh represents all the branches of the tree, allowing the homogeneous application of textures and algorithms to simplify meshes. 2004 Elsevier Inc. All rights reserved.
