Light interception capability is a critical factor affecting the growth, development, fruit yield and quality of fruit trees; thus, it is beneficial to cultivate optimal canopy types with high light interception efficiency. In this study, we present a quantitative method of analyzing light interception by tree canopies based on a virtual plant model. A detailed three-dimensional (3D) peach model with...
Terrestrial Laser Scanner (TLS) has been used to record three-dimensional (3D) point cloud data of trees, and this data is being further processed to extract morphological parameters of standing trees and reconstruct 3D geometric model. We present an efficient, high-accuracy and photorealistic 3D single tree reconstruction technique based on the point cloud of individual standing tree acquired mainly...
Virtual Geographic Environments (VGEs) represent a new analytical tool for understanding geographic processes. Among the fundamental solutions to advancing and deepening the development of VGEs are geographic modeling, geographic simulation, and geographic knowledge sharing. Forest is a major component of the geographic environment. This article proposes an integrated approach for analyzing and exploring...
A longan (Dimocarpus longan Lour.) growth and development simulation model was created by integrating existing knowledge of different aspect of the Longan architecture and physiology. Field investigation and measurements were conducted in longan orchard in order to acquire architectural characteristics of longan tree. The three-dimensional canopy model of longan is consisted of trunk, branches and...
