🌳 Procedural Tree Generation using MATLAB

📚 Overview

This MATLAB script implements a procedural tree generation algorithm that creates a forest of trees with varying structural properties. It employs a stochastic approach to generate tree parameters, simulate branching structures, and visualize the results in 3D. The model is designed for use in radiorealistic vegetation modeling and LiDAR-based simulations.

🛠 Key Features

• Tree Population Control: Adjust the number of trees, height range, and bud distribution.
• Branching System: Categorizes branches into trunk, primary, secondary, tertiary, and non-use branches based on their radius.
• Randomized Positioning: Uses a structured grid with offsets to distribute trees in a defined area.
• 3D Visualization: Plots tree structures in a 3D environment with labeled receivers.
• Receiver Perspective Analysis: Simulates a receiver’s view of the forest and identifies visible branches.

🎯 Research Application

This script can be utilized in remote sensing, forest ecology, and radiative transfer modeling to analyze the impact of tree structures on wave propagation and environmental factors.

🔄 Workflow

1. Initialize Parameters: Define tree count, branch magnitude, height limits, and spatial distribution.
2. Generate Trees: Use randomized methods to define branching structures based on biological models.
3. Classify Branches: Segregate tree components based on diameter thresholds.
4. Visualize Forest: Plot trees in 3D with color-coded branches and receiver positions.
5. Receiver Perspective Simulation: Identify which tree components fall within the receiver’s cylindrical viewing range.
