论文摘要
在本文中，我们提出了一种模拟树木的新方法，包括它们的树枝，子分支和树叶。这种方法结合了生物学发展，数学模型和计算机图形的理论，并通过完整的几何形状生产模拟的树木和森林。具体而言，我们采用Lindenmayer过程来模拟树木的分支模式，并修改3D CAD开发的对象文件的可用测量和尺寸，以创建自然外观的子分支和叶子。随机化已添加到所有分支，子分支和叶子的位置中。为了模拟森林，我们采用不均匀的泊松过程来产生树木的随机位置。我们的方法可用于创建复杂的结构化3D虚拟环境，以测试新的传感器和训练机器人算法。我们期待将这种方法应用于测试模拟环境中模仿蝙蝠飞行的生物纳尔传感器。
In this article, we propose a new approach for simulating trees, including their branches, sub-branches, and leaves. This approach combines the theory of biological development, mathematical models, and computer graphics, producing simulated trees and forest with full geometry. Specifically, we adopt the Lindenmayer process to simulate the branching pattern of trees and modify the available measurements and dimensions of 3D CAD developed object files to create natural looking sub-branches and leaves. Randomization has been added to the placement of all branches, sub branches and leaves. To simulate a forest, we adopt Inhomogeneous Poisson process to generate random locations of trees. Our approach can be used to create complex structured 3D virtual environment for the purpose of testing new sensors and training robotic algorithms. We look forward to applying this approach to test biosonar sensors that mimick bats' fly in the simulated environment.
