Tree and Plant Volume Imaging —An Introductive Study towards Voxelized Functional Landscapes

摘要

Virtual vegetation, and more precisely its geometrical representation and visualization ask both high memory space and high computing time costs. The main contribution of this paper is to propose an open, fast, efficient 3D plant exhaustive spatial representation from tree/plant skeleton discretization. This voxel based representation can carry topological, geometrical and functional information. Two single application examples are presented: biomass volume estimation and visualization. Diameter retrieval is exposed leading to a classical exhaustive voxel plant description in a constant time process. Including discrete terrain voxel representation, volume rendering shows the interest of the method on small landscapes for fast visualizations purposes. Perspectives point out that this approach could be a key feature for functional landscape simulations.
