2 boyutlu eskizlerden 3 boyutlu düzensiz yüzeyli nesneler modelleme

Using sketches for 3D modelling is a popular research area, which is expected sinceusing 2D sketches feels natural to most of the artists. Many techniques have beenproposed to enable an intuitive and competent tool for 3D object creation. Inthe light of the previous research in this area, we designed a system that enablescreation of 3D free-form objects with details. Our system aims to enable usersto easily create simple free-form objects using strokes and perturb their surfacesusing sketches that provide contours of details and shading information. Weprovide the user with the ability to create a 3D simple object just by drawingits silhouette. We take this stroke input and create a simple 3D object. Thenwe allow the user to shade the parts of the 2D silhouette drawn before. Wetake the shading information and use shape from shading techniques to create aheight map and apply the height map on the surface of the object to construct aperturbed surface for the previously created mesh. With our system, it is possibleto create and modify 3D meshes easily and intuitively.
