边框线是在模型上添加一个边框，而不是发光呼吸灯，如果需要模型发光效果
可以看一下我的另一篇文章 模型发光

效果图：

var material = new THREE.MeshPhongMaterial({
        color: 0xccebff,
        specular: 0x00ff00,
        transparent: true,
        opacity: 0.5
      })
      var geometry = new THREE.BoxGeometry(10, 10, 10)
      for (var i = 0; i < 50; i++) {
        var mesh = new THREE.Mesh(geometry, material)
        var posX = Math.random() * 2500 - 1000
        var posZ = Math.random() * 2000 - 1000
        var scaleY = Math.random() * 30 + 10
        mesh.scale.set(10, scaleY, 10)
        mesh.position.set(posX, scaleY * 5, posZ)
        mesh.updateMatrix()
        mesh.materixAutoUpdate = false
        this.selectedObjects.push(mesh)
        this.scene.add(mesh)
        //绘制边框线
        const lineGeom = new THREE.EdgesGeometry(geometry)
        const lineMaterial = new THREE.LineBasicMaterial({
          color: 0x018bf5,
          linewidth: 10,
          linecap: 'round',
          linejoin: 'round'
        })
        const line = new THREE.LineSegments(lineGeom, lineMaterial)
        line.scale.copy(mesh.scale)
        line.rotation.copy(mesh.rotation)
        line.position.copy(mesh.position)
        this.scene.add(line)
      }
