1. 设置entity材质

• 添加棋盘纹理材质

  // 棋盘纹理
  let material = new Cesium.CheckerboardMaterialProperty({
  evenColor: Cesium.Color.RED,
  oddColor: Cesium.Color.YELLOW,
  repeat: new Cesium.Cartesian2(2, 2),
  });
  

• 添加条纹纹理材质

  // 条纹纹理
  let material = new Cesium.StripeMaterialProperty({
  evenColor: Cesium.Color.WHITE,
  oddColor: Cesium.Color.YELLOW,repeat: 8,
  });
  

• 添加网格纹理材质

  // 网格纹理
  let material = new Cesium.GridMaterialProperty({
  color: Cesium.Color.YELLOW,
  cellAlpha: 0.2,
  lineCount: new Cesium.Cartesian2(4, 4),
  lineThickness: new Cesium.Cartesian2(4.0, 4.0),
  });
  

  

• 添加虚线材质

  // 设置虚线材质
  let material = new Cesium.PolylineDashMaterialProperty({dashLength: 30,color: Cesium.Color.RED,
  });
  

• 设置箭头材质

  let material = new Cesium.PolylineArrowMaterialProperty(Cesium.Color.RED);
  

• 设置发光飞线效果

  let material = new Cesium.PolylineGlowMaterialProperty({// 设置发光程度glowPower: 0.8,// 尾椎缩小程度taperPower: 0.7,color: Cesium.Color.RED,
  });
  

2. 编写着色器自定义材质

// 编写着色器修改材质// https://cesium.com/downloads/cesiumjs/releases/b28/Documentation/let material1 = new Cesium.Material({fabric: {uniforms: {uTime: 0,},source: `czm_material czm_getMaterial(czm_materialInput materialInput){// 生成默认的基础材质czm_material material = czm_getDefaultMaterial(materialInput);// material.diffuse = vec3(materialInput.st+uTime, 0.0);float strength = mod((materialInput.s-uTime) * 10.0, 1.0);material.diffuse = vec3(strength, 0.0, 0.0);return material;}`,},});//添加补间动画gsap.to(material1.uniforms, {uTime: 1,duration: 2,repeat: -1,ease: "linear",});// 图元let primitive = new Cesium.Primitive({geometryInstances: [instance, instance2],appearance: appearance,show: true,});// 添加到viewerviewer.scene.primitives.add(primitive);

3. Appearance编写着色器修改外观

 let appearance = new Cesium.EllipsoidSurfaceAppearance({fragmentShaderSource: `in vec3 v_positionMC;in vec3 v_positionEC;in vec2 v_st;uniform float uTime;void main(void){czm_materialInput materialInput;out_FragColor = vec4(v_st,uTime, 1.0);}`,});console.log(appearance);appearance.uniforms = {uTime: 0,};gsap.to(appearance.uniforms, {uTime: 1,duration: 2,repeat: -1,yoyo: true,ease: "linear",});// 04-图元let primitive = new Cesium.Primitive({geometryInstances: [instance, instance2],appearance: appearance,});

4. 自定义materialProperty材质

//创建自定义材质class CustomMaterialPropery {constructor() {this.definitionChanged = new Cesium.Event();Cesium.Material._materialCache.addMaterial("CustomMaterial", {fabric: {type: "CustomMaterial",uniforms: {uTime: 0,},source: `czm_material czm_getMaterial(czm_materialInput materialInput){// 生成默认的基础材质czm_material material = czm_getDefaultMaterial(materialInput);material.diffuse = vec3(materialInput.st, uTime);return material;}`,},});this.params = {uTime: 0,};gsap.to(this.params, {uTime: 1,duration: 2,repeat: -1,yoyo: true,});}getType() {// 返回材质类型return "CustomMaterial";}getValue(time, result) {result.uTime = this.params.uTime;// 返回材质值return result;}}let material = new CustomMaterialPropery();
