  I have a three-dimensional space Khth years I've how used opengl among'm moving my file format is obj   
  Get better translation software [smile].But if I understand right you're asking how to move an object in a 3-dimensional world.  You should check out the nehe tutorials, they have examples of moving 3D objects: http://nehe.gamedev.netAnother short answer would be "Linear Algebra".  Basically you want to modify the modelview matrix of the object being rendered such that it's rendered in the correct place.  There are many mechanisms by which to do that which include adding in a 3rd party physics library.  But... baby steps, start with the nehe tutorials.-me
