3D Tree Modeling Based on Abstract Parametric L-System
Chen Chen, Di Wang · 2023
Tree modelling is a necessary topic for discussion in virtual world construction. This paper presents a new approach that uses point cloud reconstructions of the resulting tree skeleton to form a compact parametric L-system expression after branching parameter abstraction. The proposed strategy can generate diverse new parametric L-system expressions under the control of several iterations, allowing the construction of a set of tree models with diverse growth patterns but more similar to real trees. This technique makes it possible to create large-scale tree models in virtual environments.
