Installation

TypeScript (JavaScript) only

If you want the TypeScript (JavaScript) only mode, any installation procedure is not required.

Build Cloud Server

However, if you want to install the C++ mode, you've to install Visual C++ Redistributable for Visual Studio 2015. After the installation, execute release/cpp/Packer.exe. Then a cloud server deducting packer solution will be opened. After running the cloud server, open release/ts/index.html.

You also can separate cloud server(C++) and clients(Web), let users to connect remote Packer server, by editing ip address in release/ts/server.xml

Implementation

Design

alt text

Languages
  • C++
    • Server solving packing problem.
    • Deduct the best optimization result with genetic algorithm
  • TypeScript
    1. Act a role of client connecting to C++ server.
    2. Do packing itself without C++ server and do not use genetic algorithm.
      • The optimization result can be inferior than C++
  • Flex
    • I'm not familiar with HTML5
    • To realize item editor faster, I've adopted the Flex.
    • However, it will be replaced to the HTML5 soon.
