title: Moving meshes to given positions with OpenGL
body: <p>If you've experienced with Actionscript before you probably know how movie clips work, they have width,height,x,y values you can set on them and it's really simple to change them.</p>
  
  <p>But now, I tried using libgdx (Java) &amp; LibCinder (C++) and there's a lot into it, rendering is now done via OpenGL, and requires shaders etc', 
  I managed to import a 3d mesh that I created with it's texture, but now things are a bit strange when it comes to changing the location / size of the mesh..</p>
  
  <p>In both of the libraries I tried to use, there's no real way to change the size or position of the mesh as I thought..
  (At first, I was expecting something like mesh.width/height, mesh.scale, mesh.x/y/z)</p>
  
  <p>So my question is, what is the actual approach of setting those values?</p>
