Forge 查看器：如何在材质中禁用透明度

Question

为了在 Forge 查看器中为许多对象设置颜色，我做了一个扩展，它在材质上设置颜色并将对象连接到它。这样我只更新查看器一次而不是多次。但是我想没有透明度，但我一直得到它，即使我已经将材料透明度设置为假。我该如何解决这个问题？

void setColorMaterial(material, viewer) 
{
    var mesh_material = this.addMaterial(material, viewer)

    for (var i=0; i< material.dbIds.length; i++) {
        var dbid = material.dbIds[i]

        var it = viewer.model.getData().instanceTree
        it.enumNodeFragments(dbid, function (fragId) {
            var renderProxy = viewer.impl.getRenderProxy(viewer.model, fragId)
        renderProxy.meshProxy = new THREE.Mesh(renderProxy.geometry, renderProxy.material)
        renderProxy.meshProxy.matrix.copy(renderProxy.matrixWorld)
        renderProxy.meshProxy.matrixWorldNeedsUpdate = true
        renderProxy.meshProxy.matrixAutoUpdate = false
        renderProxy.meshProxy.frustumCulled = false
        viewer.impl.addOverlay(material.name, renderProxy.meshProxy)
      }, false)
    }
    this.materialHolder.push(material)
    viewer.impl.invalidate(true)
}

void addMaterial(material, viewer) 
{
    var mesh_material = new THREE.MeshPhongMaterial({
        color: #007dfa,
        opacity: 1,
        transparent: false,
        name: 'materialName'
})
    viewer.impl.matman().addMaterial(this.newGuid(), mesh_material)
    viewer.impl.createOverlayScene(material.name, mesh_material, mesh_material)
}

首先，感谢您的回复，不幸的是，透明度仍然存在。

Alex：我移除了不透明度。

Bryan：我根据您的建议修复了代码（据我了解）。下面是更新的代码。

从链接中的图片可以看出，透明度仍然存在。任何其他建议将不胜感激。

setColorMaterial(material, viewer) {
    var mesh_material = this.addMaterial(material, viewer)

    for (var i=0; i< material.dbIds.length; i++) {
        var dbid = material.dbIds[i]

        //from dbid to node, to fragid
        var it = viewer.model.getData().instanceTree
        it.enumNodeFragments(dbid, function (fragId) {
            var renderProxy = viewer.impl.getRenderProxy(viewer.model, fragId)
            renderProxy.meshProxy = new THREE.Mesh(renderProxy.geometry, mesh_material)
            renderProxy.meshProxy.matrix.copy(renderProxy.matrixWorld)
            renderProxy.meshProxy.matrixWorldNeedsUpdate = true
            renderProxy.meshProxy.matrixAutoUpdate = false
            renderProxy.meshProxy.frustumCulled = false
            viewer.impl.addOverlay(material.name, renderProxy.meshProxy)
        }, false)
    }
    viewer.impl.invalidate(true)
}

addMaterial(material, viewer) {
  var mesh_material = new THREE.MeshPhongMaterial({
      color: material.color,
      transparent: false,
      blendEquationAlpha: false,
      name: material.name
  })
  viewer.impl.matman().addMaterial(this.newGuid(), mesh_material)
  viewer.impl.createOverlayScene(material.name, mesh_material)
  return mesh_material
}

Transparency still there image
