3D Bin Packing

This is a GUI 3D bin packing problem solver written in go and typescript using:

1. wails - a gui framework that makes it possible to write desktop applications using Go and web technologies
2. vite - next generation frontend tooling
3. react - a declarative js library for building gui
4. mui (material-ui) - a react components library
5. zustand - a minimalistic state management library
6. three.js - a general purpose 3D library
7. react-three/fiber - a react renderer for three.js

The following algorithms are available to use:

1. A custom implementation of B-Cell Algorithm
2. Genetic algorithms based on different evolution models: Darwin and de Vries

How to build

Prerequisites

• go 1.18
• node 15+
• wails v2 beta36+: go install github.com/wailsapp/wails/v2/cmd/wails@latest
• you might need to install some additional packages/dependencies:
  • Fedora 36 requires webkit2gtk3-devel package to successfully build the application:
    sudo dnf install -y webkit2gtk3-devel
  • Check official wails v2 installation guide if you use other Linux distro | MacOS | Windows

Build command

wails generate module && wails build

Development

wails generate to generate wailsjs runtime and go/ts bindings
wails dev to run the app in development mode (with hot reload)
wails dev -browser to run the app in development mode in a browser

Research

Optimal parameters

The research of both algorithms was done on a randomly generated task of size 47 (1 container and 47 blocks)

For this task the best solution is 0.773552 (there is no solution where the container is fully filled)

BCA	GA

Comparison

Comparison of speed and efficiency was also done out using randomly generated tasks of different sizes
(except for the first task of size 10, which has 1.0 solution)

Speed	Efficiency
