The world of logistics is a puzzling one, with every box needing to find its perfect place in the shipping container. Enter the 3D Bin Container Packing library, a brilliant tool designed to solve this very challenge. With its capabilities in 3D rectangular bin packing, this library efficiently matches sets of 3D items to various containers, making your packing process a breeze!

Understanding 3D Bin Packing with an Analogy

Imagine you are tasked with packing various items into a series of toy boxes. Each toy represents a stackable item, which can be freely rotated to fit into different orientations. Your goal is to maximize space within the boxes, while ensuring that no toys fall out or exceed weight limits. The 3D Bin Container Packing acts as your master organizer, employing smart algorithms to determine the best arrangement of toys to optimize space in the boxes.

Getting Started

To use the 3D Bin Container Packing library, you’ll first need to set it up in your project. Below are the necessary steps for Maven and Gradle users:

Obtain the Library

• Maven: Add the following dependency to your pom.xml:

    <dependency>
        <groupId>com.github.skjolber.3d-bin-container-packing</groupId>
        <artifactId>core</artifactId>
        <version>$3d-bin-container-packing.version</version>
    </dependency>
    

• Gradle: Add this to your build.gradle file:

    ext {
        containerBinPackingVersion = '3.0.9'
    }
    dependencies {
        implementation "com.github.skjolber.3d-bin-container-packing:core:$containerBinPackingVersion"
    }
    

Using the Library

Once you’ve correctly installed the library, you can start using it to pack items into containers. Here’s how to do it including creating stackable items:

List<StackableItem> products = new ArrayList<>();
products.add(new StackableItem(Box.newBuilder().withId("Foot").withSize(6, 10, 2).withRotate3D().withWeight(25).build(), 1));
products.add(new StackableItem(Box.newBuilder().withId("Leg").withSize(4, 10, 1).withRotate3D().withWeight(25).build(), 1));
products.add(new StackableItem(Box.newBuilder().withId("Arm").withSize(4, 10, 2).withRotate3D().withWeight(50).build(), 1));

// Define a container
Container container = Container.newBuilder()
        .withDescription(1)
        .withSize(10, 10, 3)
        .withEmptyWeight(1)
        .withMaxLoadWeight(100)
        .build();

The code snippet above defines a list of stackable items and a container. Once you have these prepared, you can pack them:

PackagerResult result = packager.newResultBuilder()
        .withContainers(containerItems)
        .withStackables(products)
        .build();

if(result.isSuccess()) {
    Container match = result.get(0);
    // Handle success
}

Algorithms at Play

The 3D Bin Container Packing library supports different packing algorithms:

• Plain Packager: A basic, yet effective packing algorithm.
• Largest Area Fit First (LAFF): This method prioritizes larger boxes, ensuring better stability in the packing process.
• Brute-force Packager: Useful for smaller sets of items, this approach checks every possible arrangement of boxes.

Troubleshooting

If you encounter any challenges during implementation, consider the following troubleshooting tips:

• Ensure all dependencies are correctly specified in your project file (Maven/Gradle).
• Verify that the dimensions and weights of your stackable items and containers do not exceed the defined limits.
• Debug any issues in your packing logic to understand why certain items aren’t fitting as expected.
