I created a tube from two points, and I need show it in PLC as a pointCloud. Can I resample it as a pointcloud file(Just many points vtx coordinate). I exported cube as a ply but the file is still be a mesh model.

A surface mesh is a point cloud (with some additional information), so you don’t need to do any conversion create point cloud from a mesh.

What is PLC?

What is your overall goal?

The cube.ply(export from slicer) just contains top and button circle points, but no body points.  
I donnot know vtk/slicer could fill the tube body with points.  
What am I doing is following the picture:

It is not clear why this is a problem.

To get help with this, you need to be more specific about what point cloud do you need and why. The “why” (high-level goal) is important because it helps in understanding the task even if requirements are incomplete; and it ensures we solve the right problem.
