In this paper, we address the problem of creating 3D modeling from sketches. We present a fully automatic Sketch-Based Modeling methodology capable of creating textured 3D models from three 2D drawings. Creating 3D models from real-life objects is a laborious task, usually produced manually demanding specific, highly specialized human resources such as 2D and 3D artists. Although this process is consolidated in the industry and it has been used successfully in practice to create high-quality models, it is slow and expensive. Our proposed method uses a set of sketches of an object in different views produced by a 2D artist to automatically generate a 3D model and a diffuse color map for that object. We propose a novel constraint to improve the silhouette carving methods, which were originally not capable of modeling concave surface. We assess the quality of the 3D models generated by our method comparing it with other techniques of similar approach and of other photo-consistency based methods. Our experiments show that our approach creates more accurate surfaces compared to the similar approach and photo-consistency based methods.
