Creating a usdz cube of any size

create-usds.js

let fs = require('fs');

function createUSDZ(length, width, height) {
    // Offset where the x, y, z scale properties are set
    const byteOffset = 1344;

    fs.readFile('cube.usdz', null, function (err, data) {

        let view = new DataView(data.buffer);

        // Set the scale for the x, y, z axis
        view.setFloat32(byteOffset, length, true);
        view.setFloat32(byteOffset + 4, width, true);
        view.setFloat32(byteOffset + 8, height, true);

        fs.writeFile('new_cube.usdz', view, function (err, data) {
          if (err) {
            return console.log(err);
          }
        });
    });
}

// Example usage
createUSDZ(1, 1, 2);
