Creating a Depth-of-Field Effect Tutorial - OpenGL Tutorials in Delphi

 To create a Depth-of-Field effect we render the scene 8 times accumilating each time.

For every time we render the scene, we "pivot" the viewangle around the gold Sphere.

This way it seems that we focus on the gold Sphere.

The further away any Sphere is from this one, the more blurred it will be.
