Points to Mesh Example

Example of generating a triangulation from a pointcloud.

• C++

  #include <MRMesh/MRPointsLoad.h>
  #include <MRMesh/MRPointCloud.h>
  #include <MRMesh/MRPointCloudTriangulation.h>
  #include <MRMesh/MRMeshSave.h>
  #include <iostream>
   
  int main()
  {
      // load points
      auto loadRes = MR::PointsLoad::fromAnySupportedFormat( "Points.ply" );
      if ( !loadRes.has_value() )
      {
          std::cerr << loadRes.error() << "\n";
          return 1; // error while loading file
      }
      auto triangulationRes = MR::triangulatePointCloud( *loadRes );
      assert( triangulationRes ); // can be nullopt only if canceled by progress callback
   
      auto saveRes = MR::MeshSave::toAnySupportedFormat( *triangulationRes, "Mesh.ctm" );
      if ( !saveRes.has_value() )
      {
          std::cerr << saveRes.error() << "\n";
          return 1; // error while saving file
      }
      return 0;
  }

• Python

  from meshlib import mrmeshpy as mm
  from pathlib import Path
   
  pc = mm.loadPoints("Points.ply")
  nefertiti_mesh = mm.triangulatePointCloud(pc)
  mm.saveMesh(nefertiti_mesh, "Mesh.ctm")
