这很难理解，我正在使用当前的xml3D.js版本5.2。
我正在使用* BoundingBox（）功能来简化资产的定位。相机。内容已正确加载，错误显示 xml3D资源文件。它有什么特定的xml3D资产？。

因此，当我单击模型时，它会运行指定的getLocalBoundingBox（）调用并抛出错误：
getLocalBoundingBox - xml3d.js：15685TypeError： this.renderNode.getObjectSpaceBoundingBox不是函数。 （在 ＆＃39; this.renderNode.getObjectSpaceBoundingBox（BBOX）＆＃39 ;, ＆＃39; this.renderNode.getObjectSpaceBoundingBox＆＃39;未定义）
答案 0 :(得分：2)
很抱歉，您遇到了这个问题，在最近的更新中，似乎有一个错误。我已经修复了即将发布的5.2.2补丁并上传了预览版本供您试用：xml3d-5.2.2-min.js
如果你打算使用它来定位相机，你可能想要使用getWorldBoundingBox，因为本地边界框并没有考虑来自更高层的任何转换层次结构（例如您的<group transform="#m_transform">。因此，您可以获得模型本身的边界框，但它可能不在场景中的同一位置。
