title: Which parts of Graphics Pipelines are done using CPU & GPU?
body: <p>Which parts of pipelines are done using CPU and which are done using GPU?</p>
  
  <p>Reading <a href="http://en.wikipedia.org/wiki/Graphics_pipeline" rel="nofollow noreferrer">Wikipedia on Graphics Pipeline</a>, maybe my question does not precisely represent what I am asking.</p>
  
  <p>Referring to <a href="https://stackoverflow.com/questions/2856448/how-to-prevent-overdrawing">this question</a>, which "steps" are done in CPU and which are done in GPU?</p>
  
  <p><em>Edit:</em><br>
  My question is more into which parts of logical high level steps needed to display terrain+3D models [from files] are using CPU/GPU instead of which functions.</p>
