Forge ARKit - Navisworks 到 Unity
Posted
技术标签:
【中文标题】Forge ARKit - Navisworks 到 Unity【英文标题】：Forge ARKit - Navisworks to Unity 【发布时间】：2021-07-08 07:39:10 【问题描述】：我正在测试 Model Derivative API 以将我的 Navisworks 文件之一转换为 SVF，然后使用 Forge AR|VR Toolkit 在 Unity 中加载模型。我之前尝试过在 Navisworks 中使用一些 sample models，它们正确加载到 Unity。
当我尝试加载我自己的 Navisworks 文件时，它只加载一些组件而不会在统一控制台中抛出任何消息，只是“加载：115.9605317”之一：
在 Forge Viewer 中，我将模型转换为 SVF 后，它看起来像这样：
我的清单出现以下错误：

这可能是什么原因造成的？也许缺少纹理？清单的“3d 视图”节点中的“0% 完成”？
操作编辑： 刚刚发现了一些有趣的东西。大多数网格加载在随机坐标中。只有最后 2 个项目在 0,0,0 坐标中（第一张图片）。此外，这 2 个项目的比例也不正确。
在 Navisworks 文件中将模型移近原点后：
【问题讨论】：
【参考方案1】：我相信我过去曾看到过类似的问题，即 Unity 中的几何图形与原点相距甚远，以至于根本没有出现。你可以试试：
更新原始 Navisworks 文件以将模型移近原点，或 修改加载到 Unity 的所有几何图形的位置，使其更靠近原点【讨论】：
更新原始 navisworks 文件改进了一些模型。我在 op 中添加了一个新的屏幕截图。但有些部分只是在 0,0,0 处实例化，例如屏幕截图中的地板。我检查了 navisworks 文件中的这些部分，它们位于正确的位置。以上是关于Forge ARKit - Navisworks 到 Unity的主要内容，如果未能解决你的问题，请参考以下文章
