## What it is
PicoGK is a compact, open-source computational geometry kernel written in C++ with a C# layer, built by LEAP 71 as the foundation for Computational Engineering. It provides a deliberately reduced but robust instruction set for generating engineering geometry, incorporating OpenVDB, and is used to design physical parts like heat exchangers, electric motors, and 3D-printed rocket engines.

## Use cases
- generate geometry for 3D-printed parts programmatically
- build generative design models for engineering components
- design heat exchangers and electric motors via code
- create voxel-based computational geometry with OpenVDB
- automate additive manufacturing part design
- write computational engineering models in C#

## When to choose
- you want to generate engineering geometry algorithmically rather than with CAD software
- you need a lightweight, open-source geometry kernel for additive manufacturing workflows
- you prefer a small, reduced instruction set over heavyweight CAD kernels
- you work in C# or C++ and want to build computational design models

## When to avoid
- you need full-featured CAD modeling with drawings, assemblies, and parametric constraints
- you need a GUI-based design tool rather than a code-driven kernel
- your project is unrelated to physical engineering geometry or manufacturing

## Facets
- artifact type: library
- maturity: active
- function: graphics, simulation, sdk, developer-tools
- domain: simulation, graphics, developer-tools, hardware
- platform: cross-platform, cpp, dotnet
