2021年8月30日 · 简介：由于PLY1.12版本IO模块提供了PCD和PLY两种格式的读取接口，因此需要用VTK进行格式转换，完成STL到PLY格式的转换，或掩码图像到PLY格式的转换，然后用PCL进行读取并进行处理。 1、VTK 将STL转换为 PLY格式. std::string filename = "P:\\CBCT\\tooth\\upper.stl"; . vtkSmartPointer <vtkSTLReader> reader = vtkSmartPointer <vtkSTLReader>:: New(); reader-> SetFileName(filename.c_str()); reader-> Update();

2022年5月14日 · 在 VTK 中，OBJ 格式属于 VTKPoIyData 类型的文件格式。 不同 STL 的读 写类，在 VTK 类库中，8.0 版本之前是通过 vtkOBJExporter 类来完成文件的写， 在 8.0 版本之后加入了 vtkOBJWriter 类，本系统开发则是基于 vtkOBJExporter 类实现。 在 vtkOBJExporter 类中的文件写出不同 vtkOBJWriter 类对于单模型文 件数据的写，而是对场景的导出和写。

vtkPLYWriter writes polygonal data in Stanford University PLY format (see http://graphics.stanford.edu/data/3Dscanrep/). The data can be written in either binary (little or big endian) or ASCII representation. As for PointData and CellData, vtkPLYWriter cannot handle normals or vectors. It only handles RGB PointData and CellData.

Unlike vtkPolyDataXMLWriter and most other VTK writers, to write colors to the .ply file you must specify to the vtkPLYWriter: plyWriter->SetArrayName("Colors"); where your color array was created/named like this:

2020年5月3日 · VTK读取.ply根式并三维显示代码如下： std::string filename = "Greedy_Delaunay_knee_piece.ply"; //Greedy_Delaunay_knee_piece bunny-5000. vtkSmartPointer<vtkPLYReader> reader = vtkSmartPointer<vtkPLYReader>:: New (); reader-> SetFileName (filename. c_str ()); reader-> Update (); …

vtkPLYReader is a source object that reads polygonal data in Stanford University PLY file format (see http://graphics.stanford.edu/data/3Dscanrep). It requires that the elements "vertex" and "face" are defined. The "vertex" element must have the properties "x", "y", and "z". The "face" element must have the property "vertex_indices" defined.
