Abstract
This thesis proposes a method that resembles a natural pen and paper interface
to create curve based 3D sketches. The system is particularly useful for representing
initial 3D design ideas without much effort. Users interact with the
system by the help of a pressure sensitive pen tablet, and a camera. The input
strokes of the users are projected onto a drawing plane, which serves as a paper
that they can place anywhere in the 3D scene. The resulting 3D sketch is visualized
emphasizing depth perception by implementing several monocular depth
cues, including motion parallax performed by tracking user’s head position. Our
evaluation involving several naive users suggest that the system is suitable for a
broad range of users to easily express their ideas in 3D. We further analyze the
system with the help of an architect to demonstrate the expressive capabilities of
the system that a professional can benefit.
