Abstract
Using sketches for 3D modelling is a popular research area, which is expected since
using 2D sketches feels natural to most of the artists. Many techniques have been
proposed to enable an intuitive and competent tool for 3D object creation. In
the light of the previous research in this area, we designed a system that enables
creation of 3D free-form objects with details. Our system aims to enable users
to easily create simple free-form objects using strokes and perturb their surfaces
using sketches that provide contours of details and shading information. We
provide the user with the ability to create a 3D simple object just by drawing
its silhouette. We take this stroke input and create a simple 3D object. Then
we allow the user to shade the parts of the 2D silhouette drawn before. We
take the shading information and use shape from shading techniques to create a
height map and apply the height map on the surface of the object to construct a
perturbed surface for the previously created mesh. With our system, it is possible
to create and modify 3D meshes easily and intuitively.
