如何将DAE导入到SceneKit for ARKit [英] How to import a dae to SceneKit for ARKit

问题描述

如果我运行Xcode的ARKit项目模板，则可以按预期在默认装运范围内移动.

If I run Xcode's ARKit project template, I can move around the default ship as expected.

我尝试导入一些我从Blender导出的dae模型，将飞船切换到新项目，但保持代码不变.它们始终显示在视野中，但位于相机的前面.如果我尝试在模型上四处移动，它会粘在相机的前面，不会停留在相同的虚拟空间中.

I have tried importing some dae models that I have exported from Blender, switching the ship to the new item but keeping the code the same. They always show in view but position in front the camera. If I try to move around the model it sticks infront of the camera and doesn't stay in the same virtual space.

我还尝试了从另一个教程中导入dae，并且可以按预期工作.

I have also tried importing a dae from another tutorial and that works as expected.

将3d模型导出为Collada dae文件时，是否需要进行任何设置以确保其锚定到ARKit中的某个位置?

Does anything need setting when exporting a 3d model as a Collada dae file to make sure it will anchor to a position in ARKit?

推荐答案

为ARKit导入3D模型时，请确保进行以下检查:

When importing 3D-models for ARKit make sure to check:

• 文件的大小.一个单位等于1米
• 模型应以坐标原点为中心，以便于放置模型

尝试在Xcode的SceneKit编辑器中导入文件，并检查文件是否正确导入.

Try to import the file in the SceneKit editor in Xcode and check if it gets imported correctly.
