title: What's the 3D structurally simplest file format?
body: <p>From my computations, I've got a lot of raw bytes of data. I would like to view them not as an image, but as a 3D relatively-standard file. (c.f. previous question about PPM :<a href="https://stackoverflow.com/questions/16636311/what-is-the-simplest-rgb-image-format">What is the simplest RGB image format?</a> )</p>
  
  <p>I would like to put in a file some header and a bunch of <code>struct point</code>, and open this file with a standard 3d file viewer such as g3dviewer.</p>
  
  <pre><code>struct point {
      unsigned int x; // coordinates
      unsigned int y;
      unsigned int z;
      unsigned char r; // color
      unsigned char g;
      unsigned char b;
  }
  </code></pre>
  
  <p>I've already looked at the .OBJ file format, but it forces me to translate each point in a text line describing a cubic vertex.</p>
  
  <p>Does this simple 3D file format exist ?</p>
