Sketch-based modeling: A survey
نویسندگان
چکیده
User interfaces in modeling have traditionally followed the WIMP (Window, Icon, Menu, Pointer) paradigm. Though functional and very powerful, they can also be cumbersome and daunting to a novice user, and creating a complex model requires considerable expertise and effort. A recent trend is toward more accessible and natural interfaces, which has lead to sketch-based interfaces for modeling (SBIM). The goal is to allow sketches—hasty freehand drawings—to be used in the modeling process, from rough model creation through to fine detail construction. Mapping a 2D sketch to a 3D modeling operation is a difficult task, rife with ambiguity. To wit, we present a categorization based on how a SBIM application chooses to interpret a sketch, of which there are three primary methods: to create a 3D model, to add details to an existing model, or to deform and manipulate a model. Additionally, in this paper we introduce a survey of sketch-based interfaces focused on 3D geometric modeling applications. The canonical and recent works are presented and classified, including techniques for sketch acquisition, filtering, and interpretation. The survey also provides an overview of some specific applications of SBIM and a discussion of important challenges and open problems for researchers to tackle in the coming years. & 2008 Elsevier Ltd.

A survey of sketch-based 3-D modeling techniques
As 3-D modeling applications transition from engineering environments into the hands of artists, designers, and the consumer market, there is an increasing demand for more intuitive interfaces. In response, 3D modeling and interface design communities have begun to develop systems based on traditional artistic techniques, particularly sketching. Collectively this growing field of research has c...
متن کاملInteractive Geometric Modeling Using Freehand Sketches
CAD software and similar modeling systems can show 3D object models created by designers, but these advanced 3D systems demand precise data about the 3D object, especially in the steps of inputting data and making freeform surfaces. Although it has become common to use CAD/CAM systems to increase the efficiency of the industrial design process, traditional sketching is often more efficient in t...
متن کاملA 3-Dimensional Modeling System Inspired by the Cognitive Process of Sketching
Three-dimensional computer modeling software is becoming an increasingly important application to modern artists, designers, engineers, architects, and even laypersons. Where modeling applications were once extremely expensive and complex—available only to large businesses and institutions—recent advances in commodity computer hardware and the spread of consumer demand now places these applicat...
متن کاملSketch-Based Modeling with the BlobTree (sketches 0292)
Sketch-based modeling provides an intuitive and expressive interface for 3D model creation. With the Teddy [Igarashi et al. 1999] system, complex free-form 3D models could be quickly produced using a gesture interface. However, the topological modeling operations implemented in Teddy were limited by the underlying shape representation (triangle meshes). Related systems based on variational impl...
متن کاملSketch2Jewelry: Semantic feature modeling for sketch-based jewelry design
Sketch-based modeling has attracted considerable attention in recent years. In this paper, we propose a semantic feature modeling system for sketch-based jewelry design, called Sketch2Jewelry. The newly devised semantic feature class encodes specific domain knowledge (jewelry design knowledge in this paper) and supplies prolific semantic information. The advantage of using semantic features is ...
