title: Loading 'indices' from Wavefront OBJ format
body: <p>I'm developing an Android application with OpenGL ES 2.0.</p>
  
  <p>I want to load an export made with Blender 2.49b in Wavefront OBJ format. I have identified verxtex position, normal and texture.</p>
  
  <p>I want to use glDrawElements(GLenum mode, GLsizei count, GLenum type, const GLvoid *indices) to draw my mesh but I don't know how I can obtain the last parameter, indices, from a Wavefront OBJ file.</p>
  
  <p>Are faces the 'indices' that I'm looking for?</p>
  
  <p>I've found this on a forum:
  faces = indices starting with 1!</p>
  
  <p>What is the meaning of 'starting with 1!'?</p>
  
  <p>Thanks.</p>
