Perspective fun

Man! This is so cool!!
The first look at those picture, you may feel there are some lines or circle superimposed on the photograph, but it turns out that those lines are actually in the scene. Looking at a different angle, it won't be the beautiful shapes anymore. I wonder how he calculate out all the precise position of the paints, does he has a 3D model of the whole scene and raytrace it back from the optical center?

Check out his website:
Felice Varini

One of the coolest, with mirror:
mirror lines
Click on "Hor point de vue" and select "Ouvrir" to see the scene from other angles.

Oh, there's actually a page in English explaining about his passion about architectural space.

Thanks shih ching for showing the picture to us, and Danno for getting the original website.
