在Forge Viewer中加载多个模型时出现内存不足错误 [英] Out of memory error in loading multiple models in Forge Viewer

问题描述

我正在开发一个具有14个Navisworks(NWC)模型的项目.我能够将复合模型加载到查看器中(这需要一些时间，但是可以工作).

I am working on a project that has 14 Navisworks (NWC) models. I am able to load the composite model into the viewer (which takes some time but works).

但是，当我将模型一个一个地加载到Viewer中时，在全部14个模型都加载之前，我出现了内存不足的错误.文件总大小约为500MB.

However, when I am loading models one by one into Viewer, I get out of memory error before all 14 are loaded. Total file size is about 500MB.

我观察到浏览器崩溃之前(查看器在后台进行加载)，查看器的响应速度非常快.

I observed that viewer is very responsive right until browser crashes (while model loading was taking place in the background).

我怀疑这是多边形总数&的问题.几何学.我捆绑使用NOP_VIEWER.initDebugTools()扩展名，但它似乎并未显示所有模型的总数.似乎只显示第一个模型的细节.

I suspect this to be an issue of total number of polygons & geometry. I tied to use NOP_VIEWER.initDebugTools() extension but it doesn't seem to show total count from all models. It seems to show the details of only first model.

1. 有没有一种方法可以阻止Viewer在内存耗尽之前创建更多几何图形?
2. 是否可以通过DebugTools扩展找到所有模型的统计信息?
3. 还有另一种方法来计算已加载模型的多边形吗?

谢谢班杜

推荐答案

有没有一种方法可以阻止Viewer在内存耗尽之前创建更多几何图形?

Is there a way to stop Viewer creating more geometry before it runs out of memory?

尝试在加载选项中限制内存消耗:

Try and limit the memory consumption in your load options:

var config3d = {
    memory: {
        limit: 1024 // in MB
    }
};
var viewer = new Autodesk.Viewing.Viewer3D(container, config3d);

顺便说一句，默认限制为:

BTW the default limits are:

Desktop 600 MB
Mobile  195 MB

是否可以通过DebugTools扩展找到所有模型的统计信息?

Is there a way to find statistics of all models with DebugTools extension?

不幸的是，内置的 DebugTools 不适用于多个模型.

Unfortunately the built-in DebugTools does not work with multiple models.

但这不会阻止您按模型查询统计信息:

But that shouldn't stop you from querying stats on a per model basis:

let modelArray = viewer.impl.modelQueue().getModels();
let targetModel = modelArray[index];
targetModel.getGeometryList() // retrieves geometry info about a specific model

您甚至可以烘烤自己的扩展以适合多种型号.

You can even bake an extension of your own to suit multiple models.

还有另一种方法来计算已加载模型的多边形吗?

Is there another way to count polygons of loaded models?

model.getGeometryList().geomPolyCount
