title: Vertices not merged (output from Kinect Fusion)
body: <p>I have a major problem right now. I was using the kinect fusion to capture a 3D scene and output it as an .OBJ file.</p>
  
  <p>The output of the file looks something like this:</p>
  
  <p>v 123 123 123
  <br>v 123 123 123
  <br>v 123 123 123
  <br>vn 321 321 321
  <br>vn 321 321 321
  <br>vn 321 321 321
  <br>f 1//1 2//2 3//3</p>
  
  <p>Where v is the vertice, vn is normal, and f is the face. 3 vertices makes up a face, so the number of face is exacely 1/3 the number of vertices. But the problem is the output from kinect doesnt merge the vertices together. So after i import it into maya and merge them together, the number of vertice and vertice normals somehow become different!</p>
  
  <p>Number of vertice after merge: 52837
  <br>Number of vertice normal after merge: 299997
  <br>Number of face after merge: 99999</p>
  
  <p>How is that possible!? Shouldn't each vertice only have 1 vertice normal? Why is there more normal than vertices? The code that i wrote can only work if it follows that structure. Another way is to not merge the vertices together, but it may cause problems for me in the future. </p>
  
  <p>Hope someone can help me T_T</p>
