title: Adding color to vertex points in ply format
body: <p>I have a 3D point cloud each with different color/values attribute attached to each vertex of XYZ points. </p>
  
  <p>The Raw data is in simple .txt / csv form in columns i.e x, y, z, V1, V2, V3 and a new line for next point I am trying to use .ply to make images. I want to create a 3D image such as:</p>
  
  <p><img src="https://i.stack.imgur.com/ARPtZ.png" alt="this">. </p>
  
  <p>What is the appropriate code in ply format to color each surface or vertex based on each of these values? I want to create multiple maps with the same shape but mapping different colors to the surface.</p>
