3D Model of a hand specimen of the Rasthof Formation bearing lonestones and granule clusters

As supplementary material, we present a 3 D model of a hand specimen of the Rasthof Formation in .fbx format. It can be viewed in the free Windows 3D Viewer app, and imported to various other software platforms e.g. Agisoft Metashape. The model was constructed from 119 photos taken by Christoph Kettler in May 2020. The photographs were aligned, a dense point cloud generated, textured, and a 3 D model created following the standard photogrammetry workflow in Agisoft Metashape. The model was then exported to .fbx format for viewing on multiple different platforms.

作为补充材料，我们提供了一份拉斯托夫组（Rasthof Formation）手标本的三维模型，格式为.fbx。该模型可通过免费的Windows 3D Viewer应用程序查看，也可导入至Agisoft Metashape等多款其他软件平台。该模型由Christoph Kettler于2020年5月拍摄的119张照片构建而成。我们通过Agisoft Metashape遵循标准摄影测量流程，对照片进行配准、生成密集点云、添加纹理，最终创建出该三维模型。随后该模型被导出为.fbx格式，以支持在多个不同平台上查看。
