Can we have makeShared() for pcl::PolygonMesh?

Your Environment

• Operating System and version: Ubuntu 18.04
• Compiler: GCC 7
• PCL Version: Latest

Context

I was experimenting with pcl::MeshSmoothingLaplacianVTK and then I realize there isn't a makeShared() function of pcl::PolygonMesh. For example, for the usual pcl::PointCloud<pcl::PointXYZ> we can do something like below

pcl::PointCloud<pcl::PointXYZ> cld;

pcl::VoxelGrid<pcl::PointXYZ> vox;
vox.setInputCloud(cld.makeShared());
vox.filter(cld);

but I can't do the below

pcl::PolygonMesh mesh;

pcl::MeshSmoothingLaplacianVTK vtk;

vtk.setInputMesh(mesh.makeShared());
vtk.process(mesh);

eventually I figured out if I want to keep my variables as object based and avoid mixing and matching with pointers, the below seems to work

pcl::PolygonMesh mesh;

pcl::MeshSmoothingLaplacianVTK vtk;

vtk.setInputMesh(boost::make_shared<pcl::PolygonMesh>(mesh));
vtk.process(mesh);

I am wondering is there a reason there isn't a makeShared() function for pcl::PolygonMesh? Or is it simply someone need to submit a PR to add that functionality?

Start by comparing pcl::PolygonMesh with pcl::PointCloud, especially how PointCloud provides makeShared(), and inspect the MeshSmoothingLaplacianVTK setInputMesh usage. Done means PolygonMesh supports the requested shared-pointer workflow and the example can use mesh.makeShared() instead of boost::make_shared.
