"Game Development with Three.js.pdf 是一本关于使用Three.js进行游戏开发的英文原版书籍，由Isaac Sukin编写。Three.js是一个流行的JavaScript库，用于在Web上创建3D图形，使得开发者能够触及到数百万在线游戏玩家。本书旨在帮助读者掌握下一代游戏开发技术。" 在本书中，读者将学习如何利用Three.js这个强大的工具来开发引人入胜的3D游戏。Three.js库简化了WebGL的复杂性，让开发者无需深入理解底层图形编程，就能创建出交互式的3D场景。以下是通过本书可以学习到的一些关键知识点： 1. **Three.js基础**：了解Three.js的基本结构，包括场景（Scene）、相机（Camera）、光源（Light）和几何体（Geometry）。理解如何设置相机视角、创建各种类型的几何形状，并应用材质（Material）。 2. **渲染与动画**：学习如何使用渲染器（Renderer）将3D场景呈现在网页上，以及如何实现帧动画和用户交互，如鼠标或触摸事件的处理。 3. **3D模型加载**：理解如何导入和使用外部3D模型文件，如OBJ、FBX等格式，以丰富游戏内容。 4. **纹理与贴图**：掌握如何应用纹理（Texture）到3D对象上，包括颜色贴图、法线贴图、环境贴图等，以增强视觉效果。 5. **光照与阴影**：学习不同类型的光照模型，如点光源、方向光和聚光灯，以及如何设置阴影来增加场景的真实感。 6. **物理引擎集成**：了解如何结合物理引擎，如Cannon.js或ammo.js，为游戏物体添加真实世界的行为，如重力、碰撞检测等。 7. **粒子系统**：探索Three.js中的粒子系统，用于创建火焰、烟雾、爆炸等特效。 8. **动画序列与骨骼动画**：学习如何使用Three.js处理复杂的骨骼动画，适用于角色和其他生物的动态表现。 9. **性能优化**：掌握减少渲染开销的技巧，如对象合并、批处理渲染和LOD（Level of Detail）层次细节管理。 10. **WebGL和Three.js进阶**：了解WebGL的基本概念，以及Three.js库中的一些高级特性，如视口控制、深度测试、混合模式等。此外，本书还可能涵盖了游戏设计原则、用户体验、项目架构以及如何发布和分发Web游戏等方面的知识。尽管出版方已尽力确保书中信息的准确性，但读者在实际开发中仍需根据最新的技术文档和社区资源进行更新和调整。

This is the Hello, World program of Three.js—the minimum code required to get

a spinning shape rendering in the browser. The preview will automatically update

when you change any code, so go ahead and play with it and see what happens. For

example, try changing THREE.MeshBasicMaterial to THREE.MeshNormalMaterial.

What happens if you change IcosahedronGeometry to TorusKnotGeometry? Try

ddling with some numbers. Can you make the shape rotate faster or slower?

Been there, scene that

Let's dig deeper into our spinning-shape world and explain how it all works. You

can follow along with this section in the online editor or type the code into a new

HTML le.

First, there's the HTML template:

<!DOCTYPE html>

<html>

<head>

<style>

body {

background-color: #ffffff;

margin: 0;

overflow: hidden;

}

</style>

</head>

<body>

js"></script>

</body>

</html>

Nothing surprising here. We're basically just including Three.js and removing the

browser's default page margins. The <canvas> element, onto which we'll render our

scene, will be added into the DOM by our JavaScript.

Instead of using the Three.js le from the GitHub CDN, you should

download the latest Three.js build and include the local copy in your

projects. The full Three.js script can be found in the build folder of

the project or can be downloaded from https://raw.github.com/

mrdoob/three.js/master/build/three.js. In production, you

will want to use the minied version (three.min.js).

Also notice that we change the camera's location by assigning to camera.position.z.

Three.js uses a spatial coordinate system in which, by default, the x-axis increases

from left to right, the z-axis increases from back to front, and the y-axis increases

upward. Most objects have a position and scale, both of which are represented by a

three-dimensional vector (specically THREE.Vector3). They also have a rotation

represented by a THREE.Euler instance, which is an abstraction that allows treating

rotation much like a vector. All objects are initialized at the position (0, 0, 0), also

called the origin. Rotation also starts at (0, 0, 0), and scale starts at (1, 1, 1). Vectors are

very versatile, but usually all you'll need to do with them is assign to the x, y, and z

properties. For example, if we wanted to move the camera upward, we could increase

camera.position.y.

Finally, we can display the scene by asking the renderer to display it from the

camera's perspective:

renderer.render(scene, camera);

Hooray, a static 3D display! If you have been following along by rebuilding our

scene from scratch, now is the point at which you can actually see the results of your

work. Just open the HTML le in a browser. (If you're loading the three.js le from

GitHub instead of locally, you'll need to be connected to the Internet.)

A static scene isn't very fun though, so let's add animation by constructing a

render loop:

animate();

function animate() {

requestAnimationFrame(animate);

mesh.rotation.x = Date.now() * 0.00005;

mesh.rotation.y = Date.now() * 0.0001;

renderer.render(scene, camera);

}

The key here is requestAnimationFrame(), which executes the function passed to

it when the browser is ready to paint a new frame. In that function, we perform any

necessary updates to the scene (in this case, changing the mesh's rotation vector

just like we changed the camera's position vector earlier) and then ask the renderer

to repaint the canvas as before.
