# How to create a globe visualization with ThreeJS

* [ ] Checkout the github repo: <https://github.com/Yonet/WebXRWorkshop>
* [ ] npm install dependencies
* [ ] Add a sphere geometry
* [ ] Add light

```typescript
    //light
    const light = new HemisphereLight(0xffffff, 0xbbbbff, 1);
    light.position.set(0.5, 1, 0.25);
    scene.add(light);
```

### Texture and Bump map

Checkout the example below to see how bump map creates more realistic results.

{% embed url="<https://threejs.org/examples/?q=material#webgl_materials_bumpmap>" %}

* [ ] Add Texture Loader and bump and texture maps

```typescript
// Material
const texture = new TextureLoader().load("assets/images/globe/earthmap4k.jpg");
const bumpMap = new TextureLoader().load("assets/images/globe/earthbump4k.jpg");
const material = new MeshPhongMaterial({
    // color: 0xffff00 * Math.random(),
    specular: 0x222222,
    shininess: 25,
    bumpMap: bumpMap,
    bumpScale: 10,
    map: texture,
});
```

### Exercise:

* [ ] Create another sphere slightly bigger than the earth mesh and call it clouds.
* [ ] Assign MeshPhongMaterial and add the properties: {opacity:0.8, transparent: true}
* [ ] Load and assign earhclouds4k.png from the assets folder. Assign the texture as map of clouds material.
* [ ] Set the position of the clouds same as the earth mesh.
* [ ] Add animation slightly faster than earth.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.xrdev.app/mixed-reality-docs/webxr-lessons/3d-on-the-web/project/how-to-create-a-globe-visualization-with-threejs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
