Gothic pictorial stones: 3D files Gothic pictorial stones: 3D files

The 3D models were generated by structure-from-motion photogrammetry using the software “PhotoScan” (Agisoft). Each 3D model includes three files, next to the Wavefront OBJ file (.obj) a JPEG image (.jpg) with the texture and an MTL (Material Template Library File) (.mtl). The models can be opened with the open source software “MeshLab”. In order to load a model in “MeshLab”, all three files must be stored in the same location. The OBJ file is opened using the “Import Mesh” command. http://meshlab.sourceforge.net/本数据集的三维模型均通过Agisoft公司的PhotoScan软件，采用运动恢复结构（structure-from-motion）摄影测量技术生成。每个三维模型配套包含三类文件：除Wavefront OBJ格式模型文件（.obj）外，还附带承载纹理信息的JPEG图像文件（.jpg）以及材质模板库文件（MTL，Material Template Library File，.mtl）。上述三维模型可通过开源软件MeshLab打开，若需在MeshLab中加载模型，需将全部三类文件存储于同一目录下，并通过「导入网格」（Import Mesh）命令打开OBJ格式模型文件。相关链接：http://meshlab.sourceforge.net/
