Procedural Tree Generation using LSystem and Space Colonization Algorithms

A 3D procedural tree generation project.

Overview

This project demonstrates:

• 3D graphics rendering using OpenGL
• Procedural tree generation using recursive algorithms (in tree.cpp)
• Interactive camera system with multiple control modes
• Basic lighting and shading

Important Notes for Contributors

CMake Integration

• If Visual Studio prompts you with "CMake Integration" dialog asking to "enable Visual Studio's CMake support with this workspace", choose "Do not enable"
• This project uses standard Visual Studio C++ project structure, not CMake
• Enabling CMake support may cause build configuration issues

Dependencies

The project uses the following libraries:

• GLFW 3.3: Window management and OpenGL context
• GLAD: OpenGL loader
• GLM: Mathematics library
• ImGui: Immediate mode GUI library for parameter controls and interface
• OpenMP: Used for parallel processing in tree growth calculations

Building and Running

1. Set the Solution Configuration to "Debug" or "Release"
2. Build Solution (F7 or ctrl+B)
3. Run (F5)

Camera Controls

The visualization features an interactive camera system with the following controls:

Orbital Controls

• W/S: Rotate camera down/up around focus
• A/D: Rotate camera left/right around focus

Direct Movement

• Page Up/Down: Move camera up/down vertically
• Left/Right: Move camera left/right horizontally

Additional Controls

• Space: Reset camera to default position and enable auto-rotation
• Mouse Scroll: Zoom in/out during auto rotation
• Any movement key automatically disables auto-rotation
