ObjectLoader.parseGeometries()

The ObjectLoader.parseGeometries() method is part of the ObjectLoader class in Three.js. It is used to parse geometries JSON data and create Geometry instances.

Syntax

ObjectLoader.parseGeometries(geometries, onLoad);

Parameters

• geometries - A JSON object containing geometry data.
• onLoad - An optional function to execute once the geometries are loaded.

Usage

To use the ObjectLoader.parseGeometries() method, you first need to create an instance of the ObjectLoader class:

const loader = new THREE.ObjectLoader();

Then, you can call the parseGeometries() method:

loader.parseGeometries(geometries, onLoad);

In this example, geometries is a JSON object containing the geometry data that you want to parse. onLoad is an optional function that will be executed once the geometries are loaded.

Example

const loader = new THREE.ObjectLoader();

const geometries = {
  "BoxGeometry": {
    "metadata": {
      ...
    },
    "type": "BoxGeometry",
    "width": 1,
    "height": 1,
    "depth": 1,
    "widthSegments": 1,
    "heightSegments": 1,
    "depthSegments": 1
  }
};

loader.parseGeometries(geometries, function () {
  console.log("Geometries loaded!");
});

In this example, geometries is a JSON object that contains a single BoxGeometry. The parseGeometries() method is called with the geometries JSON object and a callback function that logs a message when the geometries are loaded.

Conclusion

The ObjectLoader.parseGeometries() method is a useful tool for loading geometries from JSON data in Three.js. It simplifies the process of creating Geometry instances from JSON data, allowing you to focus on creating your 3D scenes.
