Computational Design: Algorithmic Plane Prototype

This repository contains the experimental C# code used to generate the algorithmic aircraft geometry featured in my YouTube video. This project is shared as a technical reference for those interested in computational engineering and voxel-based design.

📺 Project Context

This code is a demonstration of moving away from manual CAD toward algorithmic geometry generation.

🛠 Required Frameworks & Dependencies

This project is built on the open-source stack developed by Leap71. To run or understand this code, you should familiarize yourself with:

• PicoGK: The compact Voxel-based Geometry Kernel. GitHub Repo
• LEAP71_ShapeKernel: A high-level library for generating complex engineering shapes. GitHub Repo
• Leap71 Documentation: More information on the paradigm of Computational Engineering can be found at leap71.com/picogk.

🚀 Getting Started

1. Clone this repository.
2. Ensure you have the .NET 9.0 SDK installed.
3. Dependency Setup: This project references the PicoGK NuGet package and includes specific implementations from the LEAP71 ShapeKernel. Ensure you have access to the Leap71 repositories listed above for full context.
4. Run the application:

   dotnet run

⚙️ Technical Notes

Voxel Resolution

Geometry detail is managed via AppConfig.VoxelSize.

• Lower values increase resolution and detail but require more system memory (RAM) and processing power.
• Higher values allow for faster generation and lower resource usage during testing.

Automated Log Management

To prevent "File in Use" errors during frequent restarts, the application creates a unique timestamped folder for each session:

string timestamp = DateTime.Now.ToString("yyyy-MM-dd_HH-mm-ss");
string strLogFolder = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Log", timestamp);

PicoGK requires a log directory to initialize. These folders are stored locally in the build directory and can be cleared manually to save disk space.

Namespace Management

The .csproj file is configured to remove default System.Drawing and System.Windows.Forms global usings. This is necessary to avoid naming conflicts with the PicoGK geometry kernel while still allowing for a Windows-based UI.
