Three.js 材质

快速开始

import * as THREE from "three";

// PBR material (recommended for realistic rendering)
const material = new THREE.MeshStandardMaterial({
  color: 0x00ff00,
  roughness: 0.5,
  metalness: 0.5,
});

const mesh = new THREE.Mesh(geometry, material);

材质类型概览

| 材质 | 用途 | 光照 | |------|------|------| | MeshBasicMaterial | 无光照、纯色、线框 | 否 | | MeshLambertMaterial | 哑光表面、高性能 | 是（仅漫反射） | | MeshPhongMaterial | 光亮表面、镜面高光 | 是 | | MeshStandardMaterial | PBR、真实感材质 | 是（PBR） | | MeshPhysicalMaterial | 高级PBR、清漆、透射 | 是（PBR+） | | MeshToonMaterial | 卡通着色、动画风格 | 是（卡通） | | MeshNormalMaterial | 调试法线 | 否 | | MeshDepthMaterial | 深度可视化 | 否 | | ShaderMaterial | 自定义GLSL着色器 | 自定义 | | RawShaderMaterial | 完全着色器控制 | 自定义 |

MeshBasicMaterial

无光照计算。快速，始终可见。

const material = new THREE.MeshBasicMaterial({
  color: 0xff0000,
  transparent: true,
  opacity: 0.5,
  side: THREE.DoubleSide, // FrontSide, BackSide, DoubleSide
  wireframe: false,
  map: texture, // Color/diffuse texture
  alphaMap: alphaTexture, // Transparency texture
  envMap: envTexture, // Reflection texture
  reflectivity: 1, // Env map intensity
  fog: true, // Affected by scene fog
});

MeshLambertMaterial

仅漫反射光照。快速，无镜面高光。

const material = new THREE.MeshLambertMaterial({
  color: 0x00ff00,
  emissive: 0x111111, // Self-illumination color
  emissiveIntensity: 1,
  map: texture,
  emissiveMap: emissiveTexture,
  envMap: envTexture,
  reflectivity: 0.5,
});

MeshPhongMaterial

镜面高光。适合光亮的塑料质感表面。

const material = new THREE.MeshPhongMaterial({
  color: 0x0000ff,
  specular: 0xffffff, // Highlight color
  shininess: 100, // Highlight sharpness (0-1000)
  emissive: 0x000000,
  flatShading: false, // Flat vs smooth shading
  map: texture,
  specularMap: specTexture, // Per-pixel shininess
  normalMap: normalTexture,
  normalScale: new THREE.Vector2(1, 1),
  bumpMap: bumpTexture,
  bumpScale: 1,
  displacementMap: dispTexture,
  displacementScale: 1,
});

MeshStandardMaterial（PBR）

基于物理的渲染。推荐用于真实感效果。

const material = new THREE.MeshStandardMaterial({
  color: 0xffffff,
  roughness: 0.5, // 0 = mirror, 1 = diffuse
  metalness: 0.0, // 0 = dielectric, 1 = metal

  // Textures
  map: colorTexture, // Albedo/base color
  roughnessMap: roughTexture, // Per-pixel roughness
  metalnessMap: metalTexture, // Per-pixel metalness
  normalMap: normalTexture, // Surface detail
  normalScale: new THREE.Vector2(1, 1),
  aoMap: aoTexture, // Ambient occlusion (uses uv2!)
  aoMapIntensity: 1,
  displacementMap: dispTexture, // Vertex displacement
  displacementScale: 0.1,
  displacementBias: 0,

  // Emissive
  emissive: 0x000000,
  emissiveIntensity: 1,
  emissiveMap: emissiveTexture,

  // Environment
  envMap: envTexture,
  envMapIntensity: 1,

  // Other
  flatShading: false,
  wireframe: false,
  fog: true,
});

// Note: aoMap requires second UV channel
geometry.setAttribute("uv2", geometry.attributes.uv);

MeshPhysicalMaterial（高级PBR）

扩展MeshStandardMaterial，提供高级特性。

const material = new THREE.MeshPhysicalMaterial({
  // All MeshStandardMaterial properties plus:

  // Clearcoat (car paint, lacquer)
  clearcoat: 1.0, // 0-1 clearcoat layer strength
  clearcoatRoughness: 0.1,
  clearcoatMap: ccTexture,
  clearcoatRoughnessMap: ccrTexture,
  clearcoatNormalMap: ccnTexture,
  clearcoatNormalScale: new THREE.Vector2(1, 1),

  // Transmission (glass, water)
  transmission: 1.0, // 0 = opaque, 1 = fully transparent
  transmissionMap: transTexture,
  thickness: 0.5, // Volume thickness for refraction
  thicknessMap: thickTexture,
  attenuationDistance: 1, // Absorption distance
  attenuationColor: new THREE.Color(0xffffff),

  // Refraction
  ior: 1.5, // Index of refraction (1-2.333)

  // Sheen (fabric, velvet)
  sheen: 1.0,
  sheenRoughness: 0.5,
  sheenColor: new THREE.Color(0xffffff),
  sheenColorMap: sheenTexture,
});
