Outcome

Alberti introduced the one point perspective(vanishing point) drawing method, which helps to construct a 3 dimensional space in the painting, and make the drawing more realistic.

The following picture helps to explain Alberti's one point perspective pavement construction.

In our project, we are required to do a perspective drawing in the first floor of CFA

For my works, I first found the vanishing point(point C in the above picture) and distance point(point O') in the space, and then extended lines from the vanishing point to pinpoint the position of everything.  For example, the following sketch the vanishing point is close to the center of the drawing. The position of the wall and ceiling are determined by the extended lines from the  vanishing point.(This is a perspective from the second floor)

For this one, the perspective is from the first floor, and it is a left side view. I add details and shadows in this sketching to make it look more realistic.

To sketch the first floor of CFA is pretty challenging since there are too many things in the space, the structures are very complicated. I cannot just use the extended line from the vanishing point to draw the ceiling since the ceiling is not flat. The complicated structure and lighting also make drawing the shadow more challenging.
