如何在 ARKit 应用程序中在运行时加载 SCN 或 glTF 模型? [英] How to load SCN or glTF model at runtime in ARKit app?

问题描述

在运行时从 iOS 内部的 URL 加载 3d 模型的最佳方法是什么.我试过这个 .scn 和 .gtlf 模型导入器.

我正在使用这个框架 https://github.com/prolificinteractive/SamMitiAR-iOS 我像这样加载模型:

让 virtualObjectGLTFNode = SamMitiVirtualObject(gltfUrl: URL(string:https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/Duck/glTF-Embedded/Duck.gltf")!, allowedAlignments:[.水平的])virtualObjectGLTFNode.name = "鸭子"virtualObjectGLTFNode.setAnimationForVirtualObjectRemoving {(节点，已完成)在SceneKitAnimator.animateWithDuration(持续时间:0.35/2，计时功能:.easeIn，动画:{让变换 = SCNMatrix4MakeScale(0.01, 0.01, 0.01)node.contentNode?.transform = 变换}，完成:完成)}返回 virtualObjectGLTFNode

像上面一样，我正在从远程服务器加载不同的 url，请指导我如何从远程服务器加载 3d 模型.我想要哪种格式的 url.请发送任何链接，其中包含来自远程服务器的 scn 文件先谢谢了.

解决方案

似乎是一个 url 加载器 功能在 SamMitiAR 框架中不起作用.它在 Placing and Removing Virtual Objects 部分下显示 Work in Progress.

要了解如何将模型动态加载到 ARKit 应用程序中(当模型在编译时无法访问时)，请阅读这篇文章(抱歉，有一个 Objective-C 代码):>

What is the best way to load a 3d model from a URL inside of iOS at runtime. I have tried this .scn and .gtlf models importer.

I am using this framework https://github.com/prolificinteractive/SamMitiAR-iOS I load the model like this:

let virtualObjectGLTFNode = SamMitiVirtualObject(gltfUrl: URL(string: 
   "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample- 
    Models/master/2.0/Duck/glTF-Embedded/Duck.gltf")!, allowedAlignments: 
   [.horizontal])
virtualObjectGLTFNode.name = "Duck"

virtualObjectGLTFNode.setAnimationForVirtualObjectRemoving { (node, completed) in
    SceneKitAnimator.animateWithDuration(duration: 0.35 / 2, 
                                   timingFunction: .easeIn, 
                                       animations: {
        let transform = SCNMatrix4MakeScale(0.01, 0.01, 0.01)
        node.contentNode?.transform = transform
        }, completion: completed)
    }
return virtualObjectGLTFNode

like above i am loading different url from remote server please guide me How can i load 3d models from remote server.In which format i want take url.Please send any link have that scn files from remote server Thanks adavance.

解决方案

Seems that a url loader feature doesn't work in SamMitiAR framework. It says Work in Progress under Placing and Removing Virtual Objects section.

To know how dynamically load a model into ARKit app (when a model isn't accessible at compile-time), read this article (sorry, there's an Objective-C code):

• Dynamically load Collada files in SceneKit at runtime

If you want to find out how to use different approaches when working with url, please read the following SO posts:

• ARKit - How to load .scn and texture file from server URL

• How to load a model and textures from a remote server using ARKit?

• Swift Load A 3d Asset from URL Xcode
